电气工程及自动化专业英语考试翻译课文Electric Power Systems 电力系统3.1

Section 1 Introduction 第一节介绍The modern society depends on the electricity supply more heavily than ever before.现代社会比以往任何时候对电力供应的依赖更多。

It can not be imagined what the world should be if the electricity supply were interrupted all over the world. 如果中断了世界各地的电力供应,无法想像世界会变成什么样子Electric power systems (or electric energy systems), providing electricity to the modern society, have become indispensable components of the industrial world. 电力系统(或电力能源系统),提供电力到现代社会,已成为产业界的不可缺少的组成部分。

The first complete electric power system (comprising a generator, cable, fuse, meter, and loads) was built by Thomas Edison –the historic Pearl Street Station in New York City which began operation in September 1882. 托马斯爱迪生建立了世界上第一个完整的电力系统(包括发电机,电缆,熔断器,计量,并加载)它就是位于纽约市具有历史意义的珍珠街的发电厂始于1882年9月运作。

This was a DC system consisting of a steam-engine-driven DC generator supplying power to 59 customers within an area roughly 1.5 km in radius. The load, which consisted entirely of incandescent lamps, was supplied at 110 V through an underground cable system. 这是一个直流系统,由一个蒸汽发动机驱动的直流发电机其供电面积约1.5公里至59范围内的客户。

第一章第一篇sectiongTwo variables u(t) and i(t) are the most basic concepts in an electric circuit, they characterize the various relationships in an electric circuitu(t)和i(t)这两个变量是电路中最基本的两个变量,它们刻划了电路的各种关系。

the charge e on an electron is negative and equal in magnitude to 1.60210×10 19C, while a proton carries a positive charge of the same magnitude as the electron. The presence of equal numbers of protons and electrons leaves an atom neutrally charged. 我们从基础物理得知一切物质是由被称为原子的基本构造部分组成的,并且每个原子是由电子,质子和中子组成的。

我们还知道电子的电量是负的并且在数值上等于 1.602100×10-12C,而质子所带的正电量在数值上与电子相等。

质子和电子数量相同使得原子呈现电中性。

We consider the flow of electric charges. A unique feature offlow of negative charges, as Fig.l-1 illustrates. This convention was introduced by Benjamin Franklin (l706~l790), the American scientist and inventor. Although we now know that current in metallic conductors is due to negatively charged electrons, we will follow the universally accepted conventionthat current is the net flow of positive charges. Thus, Electriccurrent is the time rate of charge, measured in amperes (A).Mathematically, the relationship among current i , charge q , andtime t is 当我们把一根导线连接到某一电池上时(一种电动势源),电荷被外力驱使移动;正电荷朝一个方向移动而负电荷朝相反的方向time in several ways that may be represented by different kindsof mathematical functions 我们通过方程(1-1)定义电流的方式表明电流不必是一个恒值函数,电荷可以不同的方式随时间而变化,这些不同的方式可用各种数学函数表达出来。

12.3 Grounding of Electrical SystemsIn general, most electrical systems must be grounded. The purposeFig. 12.4 Secondaryhigh-voltage radial distribution systemof grounding is to limit the magnitude of voltage caused by lighting, momentary surges, andaccidental contact with higher voltages. System grounds must be seaweed to provide a path of minimum impedance in order to ensure the operation of over-current devices when a ground fault occurs. Current should not flow through the grounding conductor during normal operation. Direct-current systems generally have the grounding conductor connected to the system at the supply station, and not at the individual service. Alternating-current systems, on the ether hand, must be grounded on die supply side of the main disconnect al each individual service. For specific information an the location and methyl of funding, refer to NEC Article 250.(a) Secondary high-voltage distribution system; high-voltage radical. low-voltage loop(b) Consumer distribution system withhigh-voltage and low-voltage loops Fig.12.5 12.4 Grounding of Electrical EquipmentMetal conduit and cases which enclose electrical conductors must be grounded. If the ungrounded (hot) conductor comes in contact with a metal enclosure which is not grounded, a voltage will be present between the enclosure and the ground. This presents a potential hazard. Persona comic in contact with the enclosure and ground will complete a circuit.All non-current-carrying metal parts of electrical installations should be tightly bonded together and connected to a grounding electrode. Good electrical continuity should be ensured through all metal enclosures. The current caused by accidental grounds will be conducted through the enclosures, the grounding conductor, and the grounding electrode to the earth. If the current is false enough, it mill cause the over-current device to open.12.5 Ground Fault ProtectionA ground-fault protector (GFP) is a device which senses ground faults and opens the circuit when the currant to ground reaches a predetermined value. A ground-fault circuit interrupter (GFCI) is a device which opens the circuit when very small currents flow to ground.There is no way to determine in advance the impedance of an accidental ground. Most circuits are protected by 15 A(ampere) or largerover-current devices. If the impedance of a ground fault is low enough, such devices willopen the circuit. What about currents of less than 15 A? It has been proven that currents as small as 50 mA through the heart, lungs, or brain can be fatal.Electrical equipment exposed to moisture or vibration may develop high-impedance grounds. Arcing between a conductor and the frame of equipment may cause a fire, yet the current may be less than 1 ampere.Leakage current caused by dirt and /or moisture may take place between the conductor and the frame. Portable tools are frequently not properly grounded. and the only path to ground is through the body of the operator.The ground-fault circuit interrupter was developed to provide protection against ground-fault currents of less than 15 A. the GFCI is designed to operate on two-wire circuits in which one of the two wires is grounded. The standard circuit voltages are 120 V and 277 V. The time it takes operate depends upon the value of the ground-fault current. Small currents of 20 mA or less may flow for up to 5 s before the circuit is opened. A current of 20 mA will causethe GECI to operate in less than 0.04 s. This time/current element provides a sufficient margin of safety without nuisance tripping.The GFCI operates on the principle that an equal amount of current is flowing though the two wires. When a ground fault occurs, same of the currant flowing through the ungrounded (hot) wire does not flow through the grounded wire; it completes the circuit though the accidental ground. The GFCI senses the difference in the value of current between the two wires and opens the circuit. GFCIs may be incorporated into circuit breakers installed in the line, or incorporated into a receptacle outlet or equipment.Ground-fault protectors are generally designed for use with commercial and/or industrial installations. They provide protection against ground-fault currents from 2 A (special types go as low as 50 mA) up to 2 000 A. GFPs are generally installed on the main, submain, and/or feeder conductors. GFCls are installed in the branch circuits. GFPs are generally used for three-wire, single-phase and for three-phase installations, while GECls are used for two-wire,single-phase circuits.A ground-fault protector installed on supply conductors must enclose all the circuit conductors, including the neutral, if present. When operating under normal conditions, all the current to end from the load flows through the circuit conductors. The algebraic sum of the flux produced by these currents is zero. When a phase-to-ground fault occurs, the fault currents returns through the grounding conductor. Under this condition an alternating flux is produced within the sensing device. When the flux current reaches a predetermined value, the magnetic flux causes a relay to actuate a circuit breaker.Sometimes the GFP is installed on the grounding conductor of the system. Under this condition, the unit senses the amount ofphase-to-ground current flowing in the grounding conductor. When the current exceedsthe setting of the GFP, it will cause the circuit breaker to open.The ground-fault protector is actually a specially designed current transformer connected to asolid-state relay.12. Three-Phase SystemsThe various three-phase systems in normal use will lie described. Under ideal conditions, these systems operate in perfect balance, and if a neutral conductor is present it carries zero current. In actual practice, perfectly balanced systems are seldom encountered. The electrical worker, therefore, must be to calculate values of current and voltage in unbalanced systems. Single-phase loads are frequently supplied from three-phase system. The single-phase load requirements vary considerably, making it virtually impossible to maintain a perfect balance.In a balanced three-phase system, the currents in the three lines are equal. The currents in the three phases are also equal. In other words,ILX=ILY=ILZ and Ip = Ip = Ip. if, however, ILX ≠ILF≠ILZ, then IPX≠IPY≠IPZ and the system is unbalanced (see Fig. 12. 6) .To calculate the line currents in an unbalanced three-phase system, the method in the following example may be used.Example 1Three pure resistance, single-phase loads are connected in a delta configuration across a three-phase supply, as illustrated in Fig. 12.6. Load X requires 30 A, load Y requires 50 A, and load Z requires 80 A. Calculate the current through each line wire.Example 1 applies to loads of 100 percent power factor connected in delta. With loads of different power factors, the phase angle will vary from 120°. For a wye connection, the line current is equal to the phase current.Some connections may be a combination of singe-phase and three-phase loads. Under these conditions, the phase angle between three-phase load and the single-phase load must be considered.12.7 Harmonic Effect of Fluorescent Lighting FixturesMost distribution systems in tile United States and Canada operate on a frequency of 60 Hz. certain types of electrical equipment produce secondary frequencies are multiples of the supply frequency. These secondary frequencies are called harmonics. For example, the second harmonic of 60 Hz is 120 Hz, the third harmonic is 180 Hz, and so onThe alienating flux developed by transformers,used in the ballasts of fluorescent lighting fixtures, produces a voltage which has a frequency of 180 hertz. This results in an additional current flowing in the supply conductors. The value of the current in the phase conductors is usual about 25 percent of the supply current. This third harmonic current adds to the supply current, causing a greater heating effect in the conductors. This increased heating effect is rather small, possibly in the vicinity of 3 - 5 percent.The effect on the neutral conductor is quite different. The harmonic currents from the phase conductors add together, causing a large increase in the neutral current. The heating effect is 75% - 80% greater than if the third harmonic current did not exist.CAUTION: When installing supply, feeder, and branch circuit conductors for heavy fluorescent loads, the size of the neutral conductor should be at least equal to that of the phase conductors.。

unit1 taxe A 电力变压器的结构和原理在许多能量转换系统中,变压器是一个不了缺少的原件。

它使得在经济的发电机所产生电能并以最经历的传输电压传输电能,同时对于特定的使用者合适的电压使用电能成为可能。

变压器同样广泛的应用于低功率低电流的电子电路和控制电路中,来执行像匹配电源组抗和负载以求得最大的传输效率。

隔离一个电路与另一个电路在两个电路之间隔离直流电而保证交流电继续通道的功能。

在本质上,变压器是一个由两个或多个绕组通过相互的磁通耦合而组成的,如果这其中的一个绕组,原边连接到交流电压源将产生交流磁通它的幅值决定于原边的电压所提供的电压频率及匝数。

感应磁通将与其他绕组交链,在副边中将感应出一个电压其幅值将取决于副边的匝数及感应磁通量和频率。

通过使原副边匝数比例适应,任何所期望的电压比例或转换比例都可以得到。

变压器工作的本质仅要求存在与两个绕组相交链的时变的感应磁通。

这样的作用也可以发生在通过空气耦合的两组绕组中,但用铁心或其他铁磁材料可以使绕组之间的耦合作用增强,因为一大部分磁通被限制在与两个绕组交链的高磁导率的路径中。

这种变压器通常被称作为心式变压器。

大部分变压器都是这种类型。

以下的讨论几乎全部围绕心事变压器。

为减少铁心中的涡流所产生的损耗,磁路通常由一叠薄的叠片所组成。

如图1.1所示两种常见的结构形式用示意图表示出来。

芯式变压器的绕组绕在两个矩形铁心柱上,壳式变压器的绕组绕在三个铁心柱中间的那个铁心柱上,。

0.14毫米厚的硅钢片通常被用于在低频率低于几百Hz下运行的变压器中,硅钢片具有价格低铁心损耗小,在高磁通密度下,磁导率高的理想性能,能用做高频率低能耗的标准的通讯电路中的小型变压器的铁心是由被称为铁氧体的粉末压缩制成的铁磁合金所构成的。

在这些结构中,大部分的磁通被限制在固定的铁心中与两个绕组相交链。

绕组也产生多余的磁通,像漏磁通,只经过一个绕组和另外的绕组不相交链。

虽然漏磁通只是所有磁通的一小部分,但它在决定变压器的运行情况中起着重要的作用。

系统的稳定性可以用连续系统的脉冲响应 或者离散系统的Kronrcker Δ 响应 来定义:一个连续(离散)系统是稳定的,如果其脉冲响应 (Kronrcker Δ 响应 )当时间趋于无穷大时趋于零。
An acceptable system must at minimum satisfy the three basic criteria of stability, accuracy, and a satisfactory transient response. These three criteria are implied in the statement that an acceptable system must have a satisfactory time response to specified inputs and disturbances. So although we work in the Laplace and frequency domains for convenience, we must be able to relate these two domains, at least qualitatively, to the time domain.
线性和非线性系统:如果系统所有元件都是线性的,系统就是线性的。如果任何一个是非线性的,系统就是非线性的。
时变和时不变系统:一个时不变系统或静态系统,其参数不随时间变化。当提供一个输入时,时不变系统的输出不依赖于时间。描述系统的微分方程的系数为常数。如果有一个或多个参数随时间变化,则系统是时变或非静态系统提供输入的时间必须已知,微分方程的系数是随时间而变化的。
连续和离散系统:所有变量都是时间的连续函数的系统称做连续变量或模拟系统,描述的方程是微分方程。离散变量或数字系统有一个或多个只是在特殊时刻可知的变量,如图2-1A-2b,描述方程是差分方程。如果时间间隔是可控的,系统被称做数据采样系统。离散变量随机地产生,例如:为只能接受离散数据的数字计算机提供一个输入。显然,当采样间隔减小时,离散变量就接近一个连续变量。不连续的变量,如图2-1A-2c所示,出现在开关或乓-乓控制系统中。这将分别在后续的章节中讨论。

第一章第一篇sectiongTwo variables u(t) and i(t) are the most basic concepts in an electric circuit, they characterize the various relationships in an electric circuitu(t)和i(t)这两个变量是电路中最基本的两个变量,它们刻划了电路的各种关系。

Charge and CurrentThe concept of electric charge is the underlying principle for explaining all electrical phenomena. Also, the most basic quantity in an electric circuit is the electric charge. Charge is an electrical property of the atomic particles of which matter consists, measured in coulombs (C).电荷和电流电荷的概念是用来解释所有电气现象的基本概念。

也即,电路中最基本的量是电荷。

电荷是构成物质的原子微粒的电气属性,它是以库仑为单位来度量的。

We know from elementary physics that all matter is made of fundamental building blocks known as atoms and that each atom consists of electrons, protons, and neutrons. We also know that the charge e on an electron is negative and equal in magnitude to 1.60210×10 19C, while a proton carries a positive charge of the same magnitude as the electron. The presence of equal numbers of protons and electrons leaves an atom neutrally charged.我们从基础物理得知一切物质是由被称为原子的基本构造部分组成的,并且每个原子是由电子,质子和中子组成的。

第八章第一节燃煤发电厂在化石燃料电厂中 煤 石油和天然气在炉内燃烧 燃烧产生的热能将水加热并把它转化为蒸汽 蒸汽用来驱动与发电机机械耦合的涡轮机。

典型燃煤发电厂的示意图如图8-1所示。

将发电厂的运行过程简单描述如下。

煤从储煤场取出后送入磨煤机 从磨煤机出来的煤粉与预热过的空气混合后吹入炉内燃烧。

包含一套复杂管道和汽包的炉子叫做锅炉 水泵将水送入锅炉 在锅炉内 水的温度上升直到蒸发成蒸汽。

蒸汽流向涡轮机 燃烧烟气在送入机械和静电除尘器除去99%的固体颗粒 灰 后派往烟囱。

上面描述的以煤粉 空气和水作为输入以蒸汽作为输出的单元可以叫做蒸汽发生单元 锅炉或蒸发器。

当考虑燃烧过程时 常用术语“锅炉” 而考虑水—汽循环时 常用“蒸发器”一词。

典型压力为3500psi 温度为1050度F的蒸汽通过关断阀门和控制阀门送给汽轮机 蒸汽的热能由汽轮机转化为机械能。

从汽轮机出来的乏汽在一个叫做“冷凝器”的热交换器内冷却 然后作为给水再次送回锅炉。

控制阀门允许汽轮发电机组通过调节蒸汽流量而改变输出功率。

关断阀门起一个保护作用 正常时它是全开的 如果电气输出功率突然降低 由于断路器动作 他可以突然关断以防止汽轮发电机超速 但此时控制阀门不关闭。

图8-1所示为“单级”汽轮机 但实际中采用更为复杂的“多级”布置以获得相对高的热效率。

图8-2所示为代表性的“多级“布置汽轮机示意图。

在这个多级布置中 四个蒸汽压力不同的涡轮机在机械以级联的排列形式连接在一起。

在惯常的的流程中 从锅炉 过热器 出来的高压蒸汽进入高压 HP 缸。

蒸汽从高压缸出来被送回锅炉的再热器 然后送入中压 IP 缸。

蒸汽离开中压缸后 压力很低体积膨胀很大 被送入低压 LP 缸。

从低压缸出来的乏汽在冷凝器中被冷却 然后作为锅炉给水用从汽轮机中抽出的蒸汽预热后 通过给水泵送回锅炉。

燃煤发电厂的净效率通常低于40% 也就是煤的化学能转化成电能的比例低于40% 。

尽管这个数字与大约30%的工业平均值相比具有一定的优越性 但是超过60%的化石燃料能量被转化为废热。

为了提高效率和节约一次能源 热电联产系统被长期采用 这种系统可以同时生产电能 用于工业用途或室内加热的蒸汽。

在这种系统中 总能量效率已高达60%~65%。

与燃煤电厂相关的一些问题是煤的开采与运输带来的安全危害和其他社会成本。

燃煤电厂与其他类型化石燃料电厂共同产生的环境问题包括酸雨和温室效应。

第6章(6)-3)Section 3 Operation and Control of Power Systems 第3节操作和控制的电力系统The purpose of a power system is to deliver the power the customers require in real time, on demand, within acceptable voltage and frequency limits, and in a reliable and economic manner. 该系统的目的,权力是为客户提供电力的时间为客户需要实际需求,对,在可接受的电压和频率的限制,在一个可靠和经济的方式。

In normal operation of a power system, the total power generation is balanced by the total load and transmission losses. 在电力系统正常运行的,总发电是平衡的总负荷和传输的损失。

The system frequency and voltages on all the buses are within the required limits, while no overloads on lines or equipment are resulted. 该系统的频率和电压的所有公共汽车都在规定的限额,而没有超载或设备上线造成的。

However, loads are constantly changed in small or large extents, so some control actions must be applied to maintain the power system in the normal and economic operation state. 但是,负载不断变化幅度小或大,所以一些控制行动必须适用于维持在正常和经济运行状态的电力系统。

Optimal economic operation 优化经济运行It is an important problem how to operate a power system to supply all the (complex) loads at minimum cost. 这是一个重要的问题如何操作电源系统,以提供所有的负载以最低的成本(复杂)。

The basic task is to consider the cost of generating the power and to assign the allocation of generation ( P Gi) to each generator to minimize the total "production cost" while satisfying the loads and the losses on the transmission lines. 其基本任务是考虑发电成本的生成和分配产生的分配性(P基)每个发电机,以尽量减少总的“生产成本”,同时满足负载和传输线路上的损失。

The total cost of operation includes fuel, labor, and maintenance costs, but for simplicity the only variable costs usually considered are fuel costs. The fuel-cost curves for each generating unit are specified, the cost of the fuel used per hour is defined as a function of the generator power output. When hydro-generation is not considered, it is reasonable to choose the PGi on an 总的经营成本,包括燃料,劳动和维修费用,但只有简单的可变成本通常被认为是燃料成本。

曲线每个机组的燃料成本是指定的,时间成本占燃料使用的是输出功率定义为一个函数的发电机。

当水文一代是不考虑它是合理的选择上一的PGI instantaneous basis (ie always to minimize the present production cost rate). 瞬间的基础上(即始终以减低目前的生产成本率)。

With hydro-generation, however, in dry periods, the replenishment of the water supply may be a problem. 随着水电发电,但是,在干燥的时期,供应补给的水可能是个问题。

The water used today may not be available in the future when its use might be more advantageous. Even without the element of the prediction involved, the problem of minimizing production cost over time becomes much more complicated. 今天使用的可能不会在将来提供其使用时,可能会更有利的水。

即使没有参与预测的元素,最大限度地减少生产成本的问题变得更加复杂。

It should be mentioned that economy of operation is not the only possible consideration. 应当提及的是经济运行的不是唯一可能的考虑。

If the "optimal" economic dispatch requires all the power to be imported from a neighboring utility through a single transmission link, considerations of system security might preclude that solution .如果在“最佳”的经济调度要求所有的权力,是从邻国进口的效用,通过一个单一的传输链路,系统安全的考虑可能会排除这种解决办法。

When water used for hydro-generation is also used for irrigation, nonoptimal releases of water may be required. Under adverse atmospheric conditions it may be necessary to limit generation at certain fossil-fuel plants to reduce emissions. 当水发电用于水力发电也用于灌溉,水nonoptimal释放可能是必要条件。

不良大气下它可能需要限制某些植物代化石燃料,以减少排放。

In general, costs, security and emissions are all areas of concern in power plant operation, and in practice the system is operated to effect a compromise between the frequently conflicting requirements. 一般而言,成本,安全和排放装置运行一切权力领域关注,并在实践中系统的运作产生影响,要求折衷之间经常发生冲突。

Power system control 电力系统控制Power system control is very important issue to maintain the normal operation of a system. 电力系统的控制是很重要的问题,以维持系统的正常运行。
