The report concludesThe report mainly collected from the power transmission and power system requirements related to the content of these twoareas, and analyze, to understand some of the relevant knowledge.Page2 Electrical Energy Transmission(电能输送)1 English textFrom reference 1Growing populations and industrializing countries create huge needs for electrical energy. Unfortunately, electricity is not alwaysused in the same place that it is produced, meaning long-distance transmission lines and distribution systems are necessary. Buttransmitting electricity over distance and via networks involves energy loss.So, with growing demand comes the need to minimize this loss to achieve two main goals: reduce resource consumption whiledelivering more power to users. Reducing consumption can be done in at least two ways: deliver electrical energy more efficientlyand change consumer habits.Transmission and distribution of electrical energy require cables and power transformers, which create three types of energy loss:the Joule effect, where energy is lost as heat in the conductor (a copper wire, for example); magnetic losses, where energy dissipates into a magnetic field;the dielectric effect, where energy is absorbed in the insulating material.The Joule effect in transmission cables accounts for losses of about 2.5 % while the losses in transformers range between 1 % and2 % (depending on the type and ratings of the transformer). So, saving just 1 % on the electrical energy produced by a powerplant of 1 000 megawatts means transmitting 10 MW more to consumers, which is far from negligible: with the same energy we cansupply 1 000 - 2 000 more homes.Changing consumer habits involves awareness-raising programmers, often undertaken by governments or activist groups. Simplethings, such as turning off lights in unoccupied rooms, or switching off the television at night (not just putting it into standbymode), or setting tasks such as laundry for non-peak hours are but a few examples among the myriad of possibilities.On the energy production side, building more efficient transmission and distribution systems is another way to go about it. Highefficiency transformers, superconducting transformers and high temperature superconductors are new technologies which promisemuch in terms of electrical energy efficiency and at the same time, new techniques are being studied. These include direct currentand ultra high voltage transmission in both alternating current and direct current modes. Keywords: electrical energy transmissionFrom reference 2Disturbing loads like arc furnaces and thyristor rectifiers draw fluctuating and harmonic currents from the utility grid. These nonsinusoidal currents cause a voltage drop across the finite internal grid impedance, and the voltage waveform in the vicinity becomesdistorted. Hence, the normal operation of sensitive consumers is jeopardized.Active filters are a means to improve the power quality in distribution networks. In order to reduce the injection of non sinusoidalload currents shunt active filters are connnected in parallel to disturbing loads (Fig. 1). The active filter investigated in this projectconsists of a PWM controlled three-level VSI with a DC link capacitor.The VSI is connected to the point of common coupling via atransformer. The configuration is identical with an advanced static var compensator.The purpose of the active filter is to compensate transient and harmonic components of the load current so that only fundamentalfrequency components remain in the grid current. Additionally, the active filter may provide the reactive power consumed by theload. The control principle for the active filter is rather straightforward: The load current ismeasured, the fundamental activecomponent is removed from the measurement, and the result is used as the reference for the VSI output current.In the low voltage grid, active filters may use inverters based on IGBTs with switching frequencies of 10 kHz or more. The harmonicsproduced by those inverters are easily suppressed with small passive filters. The VSI can be regarded nearly as an ideally controllablevoltage source. Inmedium voltage applications with power ratings of several MV A, however, the switching frequen cy of today’s VSIsis limited to some hundred Hertz. Modern high power IGCTs can operate at around 1 kHz. Therefore, large passive filters are neededin order to remove the current ripple generated by the VSI. Furthermore, in fast control schemes the VSI no longer represents anideal voltage source because the PWM modulator produces a considerable dead-time. In this project a fast dead-beat algorithm forPWM operated VSIs is developed [1].This algorithm improves the load current tracking performance and the stability of the activefilter. Normally, for a harmonics free current measurement the VSI currentwould be sampled synchronously with the tips of the triangular carriers. Here, the current acquisition is shifted in order to minimizethe delays in the control loop. The harmonics now included in themeasurement can be calculated and subtracted from the VSIcurrent. Thus, an instantaneous current estimation free of harmonics is obtained.Keywords: active filtersFrom reference 3This report provides background information on electric power transmission and related policy issues. Proposals for changing federaltransmission policy before the 111th Congress include S. 539, the Clean Renewable Energy and Economic Development Act,introduced on March 5, 2009; and the March 9, 2009, majority staff transmission siting draft of the Senate Energy and NaturalResources Committee. The policy issues identified and discussed in this report include:Federal Transmission Planning: several current proposals call for the federal government to sponsor and supervise large scale, on-going transmission planning programs. Issues for Congress to consider are the objectives of the planning process (e.g., a focus onsupporting the development of renewable power or on a broader set of transmission goals), determining how much authority newinterconnection-wide planning entities should be granted, the degree to which transmission planning needs to consider non-transmission solutions to power market needs, what resources theexecutive agencies will need to oversee the planning process, and whether the benefits for projects included in the transmissionplans (e.g., a federal permitting option) will motivate developers to add unnecessary features and costs to qualify proposals for theplan.Permitting of Transmission Lines: a contentious issue is whether the federal government should assume from the states the primaryrole in permitting new transmission lines. Related issues include whether Congress should view management and expansion of thegrid as primarily a state or national issue, whether national authority over grid reliability (which Congress established in the EnergyPolicy Act of 2005) can be effectively exercised without federal authority over permitting, if it is important to accelerate theconstruction of new transmission lines (which is one of the assumed benefits of federal permitting), and whether the executiveagencies are equipped to take on the task of permitting transmission lines.Transmission Line Funding and Cost Allocation: the primary issues are whether the the federal government should help pay for newtransmission lines, and if Congress should establish a national standard for allocating the costs of interstate transmission lines toratepayers.Transmission Modernization and the Smart Grid: issues include the need for Congressional oversight of existing federal smart gridresearch, development, demonstration, and grant programs; and oversight over whether the smart grid is actually proving to be agood investment for taxpayers and ratepayers.Transmission System Reliability: it is not clear whether Congress and the executive branch have the information needed to evaluatethe reliability of the transmission system. Congress may also want to review whether the power industry is striking the right balancebetween modernization and new construction as a means of enhancing transmission reliability, and whether the reliability standardsbeing developed for the transmission system are appropriate for a rapidly changing power system. Keywords: electric power transmissionPage3 Requirements of an Electric Supply System(供电系统需求)1 English textFrom reference1Connections to external 330 kV power grids are provided using an open 330 kV switchyard. The plant is connected to theLithuanian power grid using two transmission lines L-454 and L-453, 330 kV each, to the Belorussian power grid using threetransmission lines L-450, L-452 and L-705, and to the Latvian power grid using one transmission line L-451.Connections to external power grids at 110 kV are provided using the first section of the open 110 kV switchyard. The plant isconnected to the Lithuanian power grid using one transmission line “Zarasai” 110 kV, and to the Latvian power grid using onetransmission line L-632.Connections between the open switchyards at 330 kV and 110 kV are established using two coupling autotransformers AT-1 andAT-2, types ATDCTN- 200000/330. Power of each autotransformer is equal to 200 MV×A. The autotransformers have a device forvoltage regulation under load. The device type is RNOA-110/1000. 15 positions are provided to regulate voltage in a range (115 ±6) kV.The open 330 kV switchyard is designed using "4/3" principle (four circuit breakers per three connections) and consists of twosections. Circuit breakers are placed in two rows. The first section of the open switchyard 110 kV is designed using “Double systemof buses with bypass” structure. The second section of open switchyard 110 kV is connected to the first section through twocircuit breakers C101 and C102. The second section has the same design as the first one. The following transmission lines areconnected to the second section: L-Vidzy, L-Opsa, L-Statyba, LDuk Ötas. These transmission lines are intended for district powersupplies, so they are not essential for electric power supply for the plant in-house operation.Air circuit breakers of VNV-330/3150A type are used in the open 330 kV switchyard. Air circuit breakers of VVBK-110B-50/3150U1type are used in open switchyard 110 kV. To supply power loads on voltage level 330 kV and 110 kV, aerial transmission lines areused. Electrical connections of external grids 110 and 330 kV are presented in Fig. 8.1. Keywords: transmission linesFrom reference 2AbstractThis paper addresses sustainability criteria and the associated indicators allowing operationalization of the sustainability concept in the context of electricity supply. The criteria and indicators cover economic,environmental and social aspects. Some selected results from environmental analysis, risk assessment and economic studies areshown. These studies are supported by the extensive databases developed in this work. The applications of multi-criteria analysisdemonstrate the use of a framework that allows decision-makers to simultaneously address the often conflicting socio-economic andecological criteria. “EnergyGame”, the communication-oriented software recently developed by the Paul Scherrer Institute (PSI),provides the opportunity to integrate the central knowledge-based results with subjective value judgments. In this way a sensitivitymap of technology choices can be constructed in an interactive manner. Accommodation of a range of perspectives expressed inthe energy debate, including the concept of sustainable development, may lead to different internal rankings of the options butsome patterns appear to be relatively robust.IntroductionThe public, opinion leaders and decision-makers ask for clear answers on issues concerning the energy sector and electricitygeneration in particular. Is it feasible to phase out nuclear power in countries extensively relying on nuclear electricity supply andsimultaneously reduce greenhouse gas emissions? What are the environmental and economic implications of enhanced uses ofcogeneration systems, renewable sources and heat pumps? How do the various energy carriers compare with respect to accidentrisks? How would internalization of external costs affect the relative competitiveness of the various means of electricity production?What can we expect from the prospective technological advancements during the next two or three decades? Which systems orenergy mixes come closest to the ideal of being cheap, environmentally clean, reliable and at the same time exhibit low accidentrisks?How can we evaluate and rank the current and future energy supply options with respect to their performance on specificsustainability criteria?The Swiss GaBE Project on “Comprehensive Assessment of Energy Systems” provides answers to many issues in the Swiss andinternational energy arena. A systematic, multidisciplinary, bottom-up methodology for the assessment of energy systems, has beenestablished and implemented. It covers environmental analysis, risk assessment and economic studies, which are supported by theextensive databases developed in this work. One of the analysis products are aggregated indicators associated with the varioussustainability criteria, thus allowing a practical operationalization of the sustainability concept. Apart from technical and economicaspects an integrated approach needs to consider also social preferences, which may be done in the framework of multi-criteriaanalysis.Keywords: criteria indicatorsFrom reference 3Mobility of persons and goods is an essential component of the competitiveness of European industry and services as well as anessential citizen right. The goal of the EU's sustainable transport policy is to ensure that our transport systems meet society'seconomic, social and environmental needs.The transport sector is responsible for about 30% of the total final energy consumption and for about 25% of the total CO2emissions. In particular the contribution of road transport is very high (around 80% and 70% respectively). These simple data shedlight on the necessity to move towards a more sustainable transportation system, but also suggest that a technological/systemicrevolution in the field will positively impact the overall world’s sustainable development.From a technological point of view, a lower dependency from not renewable energy sources (i.e. fuel oil) of the road transport isthe main anticipated change. In particular electric engines possibly represent the natural vehicle evolution in this direction. Indeedthey have much higher energy efficiency (around three times that of internal combustion engines, ICE) and do not produce anykind of tailpipe emissions. How the electricity will be supplied to the vehicles is still unpredictable due to the too many existinguncertainties on the future development, but the electrification of the drive train will contribute to having alternative energy pathsto reduce the nearly total dependency on crude oil. In particular, vehicle range and performances allowed by the differentpossibilities will play a key role on the debate.At the moment a great attention is attracted by electric vehicles, both hybrid and not, that will allow users to recharge theirvehicles directly at home. This kind of vehicle can represent a real future alternative to the ICE vehicles in particular for whatconcerns the daily commuting trips (whose range is quite low). It is therefore important to understand what might be the impacton the electric supply system capabilities of this recharging activity.In this light the present study carries out an analysis of this impact for the Province of Milan (of particular relevant due the very highdaily commuting trips) at a 2030 time horizon. Key issue of the analysis is the estimation of a potential market share evolution for theelectric vehicles. The results obtained show that even with a very high future market penetration the impact of the vehicles on theannual energy consumption will be quite negligible. On the contrary they also show that without an appropriate regulation (e.g. theintelligent integration of electric vehicles into the existing power grid as decentralised and flexible energy storage), they couldheavily impact on the daily electric power requirements.Keywords: electric vehicles报告总结本次报告主要从网上收集了电能输送和供电系统的需求这两个方面的相关内容,并对其进行了分析,了解了一些相关知识。

优秀论文审核通过未经允许切勿外传Chapter 3 Digital Electronics3.1 IntroductionA circuit that employs a numerical signal in its operation is classified as a digital circuitputers,pocket calculators, digital instruments, and numerical control (NC) equipment are common applications of digital circuits. Practically unlimited quantities of digital information can be processed in short periods of time electronically. With operational speed of prime importance in electronics today,digital circuits are used more frequently.In this chapter, digital circuit applications are discussed.There are many types of digital circuits that electronics, including logic circuits, flip-flop circuits, counting circuits, and many others. The first sections of this unit discuss the number systems that are basic to digital circuit understanding. The remainder of the chapter introduces some of the types of digital circuits and explains Boolean algebra as it is applied to logic circuits.3.2 Digital Number SystemsThe most common number system used today is the decimal system,in which 10 digits are used for counting. The number of digits in the systemis called its base (or radix).The decimal system,therefore,the counting process. The largest digit that can be used in a specific place or location is determined by the base of the system. In the decimal system the first position to the left of the decimal point is called the units place. Any digit from 0 to 9 can be used in this place.When number values greater than 9 are used,they must be expressed with two or more places.The next position to the left of the units place in a decimal system is the tens place.The number 99 is the largest digital value that can be expressed by two places in the decimal system.Each place added to the left extends the number system by a power of 10.Any number can be expressed as a sum of weighted place values.The decimal number 2583,for example, is expressed as (2×1000)+(5×100)+(8×10)+(3×1).The decimal number system is commonly used in our daily lives. Electronically, the binary system.Electronically,the value of 0 can be associated with a low-voltage value or no voltage. The number 1 can then be associated with a voltage value larger than 0. Binary systems that use these voltage values are said to , this chapter.The two operational states of a binary system,1 and 0,are natural circuit conditions. When a circuit is turned off or the off, or 0,state. An electrical circuit that the on,or 1,state. By using transistor or ICs,it is electronically possible to change states in less than a microsecond. Electronic devices make it possible to manipulate millions of 0s and is in a second and thus to process information quickly.The basic principles of numbering used in decimal numbers apply ingeneral to binary numbers.The base of the binary system is 2,meaning that only the digits 0 and 1 are used to express place value. The first place to the left of the binary point,or starting point,represents the units,or is,location. Places to the left of the binary point are the powers of 2.Some of the place values in base 2 are 2º=1,2¹=2,2²=4,2³=8,2⁴=16,25=32,and 26=64.When bases other than 10 are used,the numbers should example.The number 100₂(read“one,zero,zero, base 2”)is equivalent to 4 in base 10,or 410.Starting with the first digit to the left of the binary point,this number this method of conversion a binary number to an equivalent decimal number,write down the binary number first. Starting at the binary point,indicate the decimal equivalent for each binary place location where a 1 is indicated. For each 0 in the binary number leave a blank space or indicate a 0 ' Add the place values and then record the decimal equivalent.The conversion of a decimal number to a binary equivalent is achieved by repetitive steps of division by the number 2.When the quotient is even with no remainder,a 0 is recorded.When the quotient process continues until the quotient is 0.The binary equivalent consists of the remainder values in the order last to first.3.2.2 Binary-coded Decimal (BCD) Number SystemWhen large numbers are indicated by binary numbers,they are difficult to use. For this reason,the Binary-Coded Decimal(BCD) method of counting was devised. In this system four binary digits are used to represent each decimal digit.To illustrate this procedure,the number 105,is converted to a BCD number.In binary numbers,To apply the BCD conversion process,the base 10 number is first divided into digits according to place values.The number 10510 gives the digits 1-0-5.Converting each displayed by this process with only 12 binary numbers. The between each group of digits is important when displaying BCD numbers.The largest digit to be displayed by any group of BCD numbers is 9.Six digits of a number-coding group are not used at all in this system.Because of this, the octal (base 8) and the binary form but usually display them in BCD,octal,or a base 8 system is 7. The place values starting at the left of the octal point are the powers of eight: 80=1,81=8,82=64,83=512,84=4096,and so on.The process of converting an octal number to a decimal number is the same as that used in the binary-to-decimal conversion process. In this method, equivalent decimal is 25810.Converting an octal number to an equivalent binary number is similar to the BCD conversion process. The octal number is first divided into digits according to place value. Each octal digit is then converted into an equivalent binary number using only three digits.Converting a decimal number to an octal number is a process of repetitive division by the number 8.After the quotient determined,the remainder is brought down as the place value.When the quotient is even with no remainder,a 0 is transferred to the place position.The number for converting 409810 to base 8 is 100028.Converting a binary number to an octal number is an importantconversion process of digital circuits. Binary numbers are first processed at a very output circuit then accepts this signal and converts it to an octal signal displayed on a readout device.must first be divided into groups of three,starting at the octal point.Each binary group is then converted into an equivalent octal number.These numbers are then combined,while remaining in their same respective places,to represent the equivalent octal number.3.2.4 Hexadecimal Number SystemThe digital systems to process large number values.The base of this system is 16,which means that the largest number used in a place is 15.Digits used by this system are the numbers 0-9 and the letters A-F. The letters A-P are used to denote the digits 10-15,respectively. The place values to the left of the .The process of changing a proper digital order.The place values,or powers of the base,are then positioned under the respective digits in step 2.In step 3,the value of each digit is recorded. The values in steps 2 and 3 are then multiplied together and added. The sum gives the decimal equivalent value of a . Initially,the converted to a binary number using four digits per group. The binary group is combined to form the equivalent binary number.The conversion of a decimal number to a ,as with other number systems. In this procedure the division is by 16 and remainders can be as large as 15.Converting a binary number to a groups of four digits,starting at the converted to a digital circuit-design applications binary signals arefar superior to those of the octal,decimal,or be processed very easily through electronic circuitry,since they can be represented by two stable states of operation. These states can be easily defined as on or off, 1 or 0,up or down,voltage or no voltage,right or left,or any other two-condition states. There must be no in-between state.The symbols used to define the operational state of a binary system are very important.In positive binary logic,the state of voltage,on,true,or a letter designation (such as A ) is used to denote the operational state 1 .No voltage,off,false,and the letter A are commonly used to denote the 0 condition. A circuit can be set to either state and will remain in that state until it is caused to change conditions.Any electronic device that can be set in one of two operational states or conditions by an outside signal is said to be bistable. Relays,lamps,switches,transistors, diodes and ICs may be used for this purpose. A bistable device .By using many of these devices,it is possible to build an electronic circuit that will make decisions based upon the applied input signals. The output of this circuit is a decision based upon the operational conditions of the input. Since the application of bistable devices in digital circuits makes logical decisions,they are commonly called binary logic circuits.If we were to draw a circuit diagram for such a system,including all the resistors,diodes,transistors and interconnections,we would face an overwhelming task, and an unnecessary one.Anyone who read the circuit diagram would in their mind group the components into standard circuits and think in terms of the" system" functions of the individual gates. Forthis reason,we design and draw digital circuit with standard logic symbols. Three basic circuits of this type are used to make simple logic decisions.These are the AND circuit, OR circuit, and the NOT circuit.Electronic circuits designed to perform logic functions are called gates.This term refers to the capability of a circuit to pass or block specific digital signals.The logic-gate symbols are shown in Fig.3-1.The small circle at the output of NOT gate indicates the inversion of the signal. Mathematically,this action is described as A=.Thus without the small circle,the rectangle would represent an amplifier (or buffer) with a gain of unity.An AND gate the 1 state simultaneously,then there will be a 1 at the output.The AND gate in Fig. 3-1 produces only a 1 out-put when A and B are both 1. Mathematically,this action is described as A·B=C. This expression shows the multiplication operation. An OR gate Fig.3-1 produces a when either or both inputs are l.Mathematically,this action is described as A+B=C. This expression shows OR addition. This gate is used to make logic decisions of whether or not a 1 appears at either input.An IF-THEN type of sentence is often used to describe the basic operation of a logic state.For example,if the inputs applied to an AND gate are all 1,then the output will be 1 .If a 1 is applied to any input of an OR gate,then the output will be 1 .If an input is applied to a NOT gate,then the output will be the opposite or inverse.The logic gate symbols in Fig. 3-1 show only the input and output connections. The actual gates,when wired into a digital circuit, would pin 14 and 7.3.4 Combination Logic GatesWhen a NOT gate is combined with an AND gate or an OR gate,it iscalled a combination logic gate. A NOT-AND gate is called a NAND gate,which is an inverted AND gate. Mathematically the operation of a NAND gate is A·B=. A combination NOT-OR ,or NOR,gate produces a negation of the OR function.Mathematically the operation of a NOR gate is A+B=.A 1 appears at the output only when A is 0 and B is 0.The logic symbols are shown in Fig. 3-3.The bar over C denotes the inversion,or negative function,of the gate.The logic gates discussed .In actual digital electronic applications,solid-state components are ordinarily used to accomplish gate functions.Boolean algebra is a special form of algebra that was designed to show the relationships of logic operations.Thin form of algebra is ideally suited for analysis and design of binary logic systems.Through the use of Boolean algebra,it is possible to write mathematical expressions that describe specific logic functions.Boolean expressions are more meaningful than complex word statements or or elaborate truth tables.The laws that apply to Boolean algebra are used to simplify complex expressions. Through this type of operation it may be possible to reduce the number of logic gates needed to achieve a specific function before the circuits are designed.In Boolean algebra the variables of an equation are assigned by letters of the alphabet.Each variable then exists in states of 1 or 0 according to its condition.The 1,or true state,is normally represented by a single letter such as A,B or C.The opposite state or condition is then described as 0,or false,and is represented by or A’.This is described as NOT A,A negated,or A complemented.Boolean algebra is somewhat different from conventional algebra withrespect to mathematical operations.The Boolean operations are expressed as follows:Multiplication:A AND B,AB,,A·BOR addition:A OR B .A+BNegation,or complementing:NOT A,,A’Assume that a digital logic circuit only C is on by itself or when A,B and C are all on expression describes the desired output. Eight (23) different combinations of A,B,and C exist in this expression because there are three,inputs. Only two of those combinations should cause a signal that will actuate the output. When a variable is not on (0),it is expressed as a negated letter. The original statement is expressed as follows: With A,B,and C on or with A off, B off, and C on ,an output (X)will occur:ABC+C=XA truth table illustrates if this expression is achieved or not.Table 3-1 shows a truth table for this equation. First,ABC is determined by multiplying the three inputs together.A 1 appears only when the A,B,and C inputs are all 1.Next the negated inputs A andB are determined.Then the products of inputs C,A,and B are listed.The next column shows the addition of ABC and C.The output of this equation shows that output 1 is produced only when C is 1 or when ABC is 1.A logic circuit to accomplish this Boolean expression is shown in Fig. 3-4.Initially the equation is analyzed to determine its primary operational function.Step1 shows the original equation.The primary function is addition,since it influences all parts of the equation in some way.Step 2 shows the primary function changed to a logic gate diagram.Step 3 showsthe branch parts of the equation expressed by logic diagram,with AND gates used to combine terms.Step 4 completes the process by connecting all inputs together.The circles at inputs,of the lower AND gate are used to achieve the negative function of these branch parts.The general rules for changing a Boolean equation into a logic circuit diagram are very similar to those outlined.Initially the original equation must be analyzed for its primary mathematical function.This is then changed into a gate diagram that is inputted by branch parts of the equation.Each branch operation is then analyzed and expressed in gate form.The process continues until all branches are completely expressed in diagram formmon inputs are then connected together.3.5 Timing and Storage ElementsDigital electronics involves a number of items that are not classified as gates.Circuits or devices of this type the operation of a system.Included in this system are such things as timing devices,storage elements,counters,decoders,memory,and registers.Truth tables symbols,operational characteristics,and applications of these items will be presented an IC chip. The internal construction of the chip cannot be effectively altered. Operation is controlled by the application of an external signal to the input. As a rule,very little work can be done to control operation other than altering the input signal.The logic circuits in Fig. 3-4 are combinational circuit because the output responds immediately to the inputs and there is no memory. When memory is a part of a logic circuit,the system is called sequential circuit because its output depends on the input plus its an input signal isapplied.A bistable multivibrator,in the strict sense,is a flip-flop. When it is turned on,it assumes a particular operational state. It does not change states until the input is altered.A flip-flop opposite polarity.Two inputs are usually needed to alter the state of a flip-flop. A variety of names are used for the inputs.These vary a great deal between different flip-flops.1. R-S flip-flopsFig.3-5 shows logic circuit construction of an R-S flip-flop. It is constructed from two NAND gates. The output of each NAND provides one of the inputs for the other NAND. R stands for the reset input and S represents the set input.The truth table and logic symbol are shown in Fig. 3-6.Notice that the truth table is somewhat more complex than that of a gate. It shows, for example,the applied input, previous output,and resulting output.To understand the operation of an R-S flip-flop,we must first look at the previous outputs.This is the status of the output before a change is applied to the input. The first four items of the previous outputs are Q=1 and =0. The second four states this case of the input to NANDS is 0 and that is 0,which implies that both inputs to NANDR are 1.By symmetry,the logic circuit will also stable with Q0 and 1.If now R momentarily becomes 0,the output of NANDR,,will rise to resulting in NANDS be realized by a 0 at S.The outputs Q and are unpredictable when the inputs R and S are 0 states.This case is not allowed.Seldom would individual gates be used to construct a flip-flop,rather than one of the special types for the flip-flop packages on a single chipwould be used by a designer.A variety of different flip-flops are used in digital electronic systems today. In general,each flip-flop type R-S-T flip-flop for example .is a triggered R-S flip-flop. It will not change states when the R and S inputs assume a value until a trigger pulse is applied. This would permit a large number of flip-flops to change states all at the same time. Fig. 3-7 shows the logic circuit construction. The truth table and logic symbol are shown in Fig. 3-8. The R and S input are thus active when the signal at the gate input (T) is 1 .Normally,such timing,or synchronizing,signals are distributed throughout a digital system by clock pulses,as shown in Fig. 3-9.The symmetrical clock signal provides two times each period.The circuit can be designed to trigger at the leading or trailing edge of the clock. The logic symbols for edge trigger flip-flops are shown in Fig.3-10.2. J-K flip-flopsAnother very important flip-flop unpredictable output state. The J and K inputs addition to this,J-K flip-flops may employ preset and preclear functions. This is used to establish sequential timing operations. Fig.3-11 shows the logic symbol and truth table of a J-K flip-flop.3. 5. 2 CountersA flip-flop be used in switching operations,and it can count pulses.A series of interconnected flip-flops is generally called a register.Each register can store one binary digit or bit of data. Several flip-flops connected form a counter. Counting is a fundamental digital electronic function.For an electronic circuit to count,a number of things must beachieved. Basically,the circuit must be supplied with some form of data or information that is suitable for processing. Typically,electrical pulses that turn on and off are applied to the input of a counter. These pulses must initiate a state change in the circuit when they are received. The circuit must also be able to recognize where it is in counting sequence at any particular time. This requires some form of memory. The counter must also be able to respond to the next number in the sequence. In digital electronic systems flip-flops are primarily used to achieve counting. This type of device is capable of changing states when a pulse is applied,output pulse.There are several types of counters used in digital circuitry today.Probably the most common of these is the binary counter.This particular counter is designed to process two-state or binary information. J-K flip-flops are commonly used in binary counters.Refer now to the single J-K flip-flop of Fig. 3-11 .In its toggle state,this flip-flop is capable of achieving counting. First,assume that the flip-flop is in its reset state. This would cause Q to be 0 and Q to be 1 .Normally,we are concerned only with Q output in counting operations. The flip-flop is now connected for operation in the toggle mode. J and K must both be made the 1 state. When a pulse is applied to the T,or clock,input,Q changes to 1.This means that with one pulse applied,a 1 is generated in the output. The flip-flop the next pulse arrives,Q resets,or changes to 0. Essentially,this means that two input pulses produce only one output pulse. This is a divide-by-two function.For binary numbers,counting is achieved by a number of divide-by-two flip-flops.To count more than one pulse,additional flip-flops must be employed. For each flip-flop added to the counter,its capacity is increased by the power of 2. With one flip-flop the maximum count was 20,or 1 .For two flip-flops it would count two places,such as 20 and 21.This would reach a count of 3 or a binary number of 11.The count would be 00,01,10,and 11. The counter would then clear and return to 00. In effect, this counts four state changes. Three flip-flops would count three places,or 20,21,and 22.This would permit a total count of eight state changes.The binary values are 000,001,010,011,100,101,110 and 111.The maximum count is seven,or 111 .Four flip-flops would count four places,or 20,21,22,and 23.The total count would make 16 state changes. The maximum count would be 15,or the binary number 1111.Each additional flip-flop would cause this to increase one binary place.河南理工大学电气工程及其自动化专业中英双语对照翻译。

电气信息类专业英语翻译Lesson40 PID Controllers and Other Controllers

比例-积分-微分控制器和其它控制器比例-积分-微分控制器 (PID)有时候另一种控制加在了PI 控制器上,这种新的控制是微分作用,也称为比率作用或超前。

它的目的是预料过程率先查看误差变化的时间速率,即微分。

描述等式如下:(4-3B-1)式中 = 微分或比率,时间单位为分钟 因此,PID 控制器有三个参数Kc 或PB, 或 和 ,必须整定这三个参数来达到满意的控制。

注意:只有一个微分整定参数 ,对于生产者,它有相同的单位:分钟。

如上所述,微分作用是通过误差求导,使控制器具有预料过程变化,也就是说,“预测未来”的能力。

“预料”的程度由整定值 决定。

考虑如图4-2B-1所示的热交换器,并利用它通过“预料过程变化的地方”来阐明其意思。

假设入口过程温度下降了一些,出口温度会如图4-3B-1所示的那样相应的下降。

在时间ta ,误差量是正值且可能很小,因此,由PI 提供的控制修正量很小。

然而,误差的微分、误差曲线的斜度是大的和正的,使得微分提供的控制修正量很大。

通过查看误差微分,控制器就可知被控量率先相当快的远离参考点。

因此可利用这个事实来帮助控制。

在时间tb 误差依然是正的且必以前更大,由比例积分提供的控制更正量的大小也比以前的大,且仍然加到控制器的输出来更大的打开蒸汽阀门,然而,在这个时刻的是误差微分是负的,表明误差正在减小,也就是说,被控量开始下降到参考点。

再次利用这个事实可知,自从误差开始下降后,微分的作用开始从其他两种形式中下降,通过这一点,过程将花费较长的时间返回到参考点,然而,在参考点上下的超调和振荡下降。

PID 控制器应用于长时间常数的系统中,典型的例子是温度浓缩回路,短时间常数(小电容)的过程很快且易受噪声干扰。

此过程的典型例子是流量回路和控制液体流压力的回路。

考虑如图4-3B-2所示的流量记录, ⎰+++=t t e K t t e K t e K m t m d )(d d )()()(D c I c c ττD τD τD τD τI τR I τ t T i (t ) t T (t ) O e (t )t a t b t a t b t O O 图4-3B-1 热交换器控制由于快速变换的噪声的微分数值很大,因此微分形式的应用仅仅造成了噪声的放大。

Lesson 1 electronic network1、短语及词汇:Electronic circuit or network ——电路或电网络Passive network ——无源网络 active network ——有源网络V oltage source ——电压源 current source ——电流源in the case of …——就…来说 Rather than ——是…而不是…of interest ——有价值的;使人感兴趣的;有意义的;2、重点句型(1)in the case of a resistor, the voltage-current relationgship is given by ohm ’s law, which states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance.就电阻来说,电压电流的关系由欧姆定律决定。

欧姆定律指出:电阻两端的电压等于电阻上流过的电流乘以电阻值(2)it may be that the inductor voltage rather than the current is the variable of interest in the circuit.或许在电路中,人们感兴趣的是电感电压而不是电感电流3、文章内容翻译(见参考译文并在课堂上讲解)对应译文:电网络电路或电网络是由电阻、电感和电容等器件以某种方式联接在一起所组成的。

如果电网络中不包含任何能源,比如电池和发电机,就叫做无源网络。

相反,如果存在一个或多个能源,则组合的系统(电网络)则称为有源网络。

当研究电网络的特性时,我们感兴趣的是电路中的电压和电流。

既然网络是由无源元件组成的,我们就必须首先来定义它们的电特性。

P 控制器和 PI 控制器
为了维持参考点,反馈控制器做出决定的方法是通过在被控量与参考点差别的基础上,计算输出。

在本单元中,我们将通过描述其操作的公式着眼于最普通的控制器。

比例控制器(P)
除了在这里不考虑的开-断控制器,比例控制器是最简单的控制器,描述其操作的方程式如下:
(4-3A-1) 或
(4-3A-2) 式中 控制器的输出,psig 或mA 参考点,psig 或mA
被控量,psig 或mA ,这是热敏电阻的信号。

误差信号,psig 或mA ,参考点与被控量的差别。

控制器增益, 或
偏差值,psig 或mA ,此值的意义在于它是误差为零时的输出,在中比例的刻度控制器中,此值通常被设定为9 psig 或12 mA 。

因为输入与输出范围是相同的(315 psig 或420mA ),输入信号和输出信号以及参考点有时候也可用分数或百分数来表示。

可以有趣的看到等式(4-3A-1)描述的是一个反作用控制器。

如果控制器变量 c(t),超过参考点r(t),误差变负,并且等式表明控制器的输出 m(t),下降。

在数学上显示正作用控制器的一般方法是使控制器的增益Kc 为负。

然而,必须牢记,在工业控制器中没有负增益,只有正增益。

反/正开关可以做到这一点。

当做正作用控制器的控制系统的数学分析时,负增益Kc 被使用。

等式(4-3A-1)和等式(4-3A-2)表明控制器的输出正比于参考点和被控量间的误差。

比例由控制器的增益Kc 给出。

此增益或控制器的灵敏度决定对于给定的误差变化,控制器输出的变化程度。

如图4-3A-1所示。

纯比例控制器的优点是只需整定一个参数Kc ,然而,它有一个很大的缺点,就是用偏移量或“稳态误差”来操作被控量。

为用图表表明此偏移量,考虑如图4-2B-2所示的液面控制回路,假设设计条件为 和 ,再假设为了使出口阀超过150gpm ,作用其上的空气压力为9 psig 。

如果入口流量增加,纯比例控制器的系统的响应如图4-3A-2所示。

控制器使被控量回到稳定值,但此值不是期望参考点。

被控量的参考点和稳定值间的差别就是偏差。

图4-3A-2显示了对应于两个不同整定

g /m 150o i ==
q q ft 6=h
参数Kc 的两条响应曲线,数据表明Kc 值越大,偏差越小,但过程响应越振荡。

然而,对于大多数过程,Kc 有最大值,超过此最大值,过程将不稳定。

增益最大值的计算我们称之为极限增益Kcu 。

为得到纯比例控制器的传递函数,等式(4-3A-1)写成
定义如下的两个偏差量:
(4-3A-3)
(4-3A-4)
那么
用拉普拉斯变换得到如下的传递函数:
c (t m (t
q i (t )/g p m
h (t )/f t

()(c t E K t M =c
)
()
(K s E s M =
简单的说,纯比例控制器是仅有一个整定参数的最简单Kc 或PB 的控制器。

此控制器的缺点是在控制器变量中用偏差操作。

在象调压槽似的一些过程中,可能不会有严重的后果。

在过程被控制在参考点上下范围内的情况下,纯比例控制器就足够了。

然而,在过程必须控制在参考点的情况下,纯比例控制器就不能提供满意的控制。

比例-积分控制器(PI)
大多数的过程不能用偏差控制,也就是说,它们必须被控制在参考点,在这些情况下,纯比例控制器中必须加入额外的信息以消除偏差,新的信息或新型控制是积分或复位作用,因此,控制器成为比例-积分控制器(PI )。

等式描述如下:

式中 积分或复位时间,分钟/次
因此,PI 控制器有两个参数Kc 和,这两个参数必须被调整以获得满意的控制。

为了理解复位时间的物理意义,考虑如图4-3A-3所示的假设的例子。

是控制器重复比例作用的时间,因此单位是分钟/次。

值越小,响应曲线越陡,
这就意味着控制器响应越快。

解释这一点的另一种方法是查看等式(4-3A-6), 值越小,
积分前的项 越大,因此,积分或复位作用的权越大。

从式中,我们注意到只要误差项存在,控制器就会不断改变其输出,从而通过对误差积分来消除误差。

记住,积分也意味着求和。

为得到PI 控制器的传递函数,式(4-3A-6)描述如下:

τI τI τI c /τK
利用式(4-3A-3)和(4-3A-4)给出的偏差的相同的定义,采用拉普拉斯变换,重新排列得到:
总之,比例-积分控制器有两个参数:增益或比例带,复位时间或复位速率。

此类控制器的优点是积分或复位作用消除偏差。
