Unit 6 LOAD FLOW STUDIES AND HVDC TRANSMISSION1.IntroductionPlanning the operation of power systems under existing conditions, its improvement and also future expansion requires the load flow studies, short circuit studies and stability studies. However the load flow studies are very important for planning, control and operations of existing systems as well as planning its future expansion as the satisfactory operation of the system depends upon knowing the effects of interconnections, new loads, new generating stations or new transmission lines, etc before they are installed. With the help of load flow studies ,we can also determine the best size and as well as the most favorable locations for the power capacitors both for the improvement of the p.f. and also raising the bus voltages of the electrical network. The load flow studies also help us to determine the best locality as well as optimal capacity of the proposed generating stations, substations or new lines. This is why the load flow studies are really important for planning the existing system as well as its future expansion.The information obtained from the load flow studies are usually the magnitude and phase angle of voltages at each bus and active and reactive power flow in each line.The extensive calculations requires both for power flow as well as for voltage determination, necessiated the use of some type of automatic calculators or computer. This led to the design of special purpose analog computer, called a.c. network analyzer some times in the year 1929. The operation of the power system under existing conditions as well as the proposed future expansion could be simulated by this device. Digital computer for the load flow studies gained importance during the beginning of 1950 and the first planning studies on the digital computer was completed by the year 1956. Today most of the load flow studies are carried out on the digital computers. This change from the network analyzer to the digital computer has resulted in greater flexibility, economy,accuracy and quicker operation.2.Formulation of Load Flow ProblemActually the load flow problem consists of calculations of voltages magnitude and its phase angle at the buses, and also the active and reactive line flows for the specified terminal or bus conditions.Type of BusesAll the buses of the power system network are generally classified into three categories viz. Generation bus, load bus and the slack bus,and two of the four quantities associated with each bus, are specified at each of the buses as shown below:(i)Generation Bus (or voltage controller bus): This is also called p-v bus and here thevoltage magnitude ׀V׀ and the real power ׀P׀ are specified.(ii)Load Bus: This is also called p-q bus and here real power ׀P׀ and reactive power ׀Q׀are specified.(iii)Slack or Swing Bus: This is also known as the reference bus and the voltage magnitude ׀V׀and phase angle δare specified here. This bus is selected to provide additional real and reactive power to supply the transmission losses since these are unknown until final solution is obtained. If slack bus is not specified, a generation bus usually with maximum real power ׀P׀ is taken as a slack bus. There can be more than one slack bus ina given scheme.Techniques of Solving Load Flow ProblemsThe development of any method for the load flow studies on the digital computer, requires the following main considerations:(i)The mathematical formulation of the load flow problem.(ii)Application of numerical technique to solve these problems.The mathematical formulation of the load flow problem is a system of nonlinear algebraic equations and since the digital computer can only perform the four basic arithmetic operations viz. additions, subtractions, multiplication and division (actually only additions and subtractions since the remaining operations can also be reduced to these two basic operations as mentioned above) numerical techniques are needed such that the equations can be solved by the digital computer. The basic equations for the purpose of load flow studies are a set of network equations which can be established either in the loop frame of reference or bus frame of reference. The coefficient of these equations (which is actually nonlinear algebraic equations) depend upon the selection of independent variables viz. voltages or currents. Thus either the impedance or the admittance matrix can be used.Useful Expressions in Passage AB: High-voltage Direct-Current TransmissionHigh-voltage direct-current (HVDC) transmission has advantages over ac transmission in special situations. The first commercial application of HVDC transmission was between the Swedish mainland and the island of Gotland in 1954. With the advent of thyristor valve converters, HVDC transmission became even more attractive. The first HVDC system using thyristor valves was the Eel River scheme commissioned in 1972, forming a 320 MW back-to-back dc interconnection between the power systems of the Canadian provinces of New Brunswick and Quebec. Thyristor valves have now become standard equipment for dc converter stations. Recent developments in conversion equipment have reduced their size and cost, and improved their reliability. These developments have resulted in a more widespread use of HVDC transmission. There are more links under construction.The following are the types of applications for which HVDC transmission has been used: (1)Underwater cable s longer than about 30 km. AC transmission is impractical for such distances because of the high capacitance of the cable requiring intermediate compensation stations.(2)synchronous link between two ac systems where ac ties would not be feasible because of system stability problems or a difference in nominal frequencies of the two systems.(3)Transmission of large amounts of power over long distances by overhead lines. HVDC transmission is a competitive alternative to ac transmission for distances in excess of about 600 km.HVDC systems have the ability to rapidly control the transmitted power. Therefore, they have a significant impact on the stability of the associated ac power systems.This paper will introduce the basic elements of HVDC systems.Converters.They perform ac/dc and dc/ac conversion, and consist of valve bridges and transformers with tap changers. The valve bridges consist of high-voltage valves connected in a 6-pulse of 12-pulse arrangement. The converter transformers provide ungrounded three-phase source of appropriate level to the valve bridge. With the valve side of the transformer ungrounded, the dc system will be able to establish its own reference to ground, usually by grounding the positive or negative end of the valve converter.Smoothing Reactors.These are large reactor s having inductance as high as 1.0 H connected in series with each pole of each converter station. They serve the following purposes:·Decrease harmonic voltages and currents in the dc line.·Prevent commutation failure in inverters.·Prevent current from being discontinuous at light load.·Limit the crest current in the rectifier during short-circuit on the dc line.Harmonic Filters.Converters generate harmonic voltages and currents on both ac and dc sides. These harmonics may cause overheating of capacitors and nearby generators, and interference with telecommunication systems. Filters are therefore used on both ac and dc sides.Reactive Power Supplies.DC converters inherently absorb reactive power. Under steady-state conditions, the reactive power consumed is about 50% of active power transferred. Under transient conditions, the consumption of reactive power may be much higher. Reactive power sources are therefore provided near the converters. For strong ac systems, these are usually in the form of shunt capacitors. Depending on the demands placed on the dc link and on the ac system, part of the reactive power source may be in the form of synchronous condensers or static var compensators. The capacitors associated with the ac filters also provide part of the reactive power required.Electrodes.Most dc links are designed to use earth as a neutral conductor for at least brief periods of time. The connection to the earth requires a large-surface-area conductor to minimize current densities and surface voltage gradients. This conductor is referred to as an electrode. As discussed earlier, if it is necessary to restrict the current flow through the earth, a metallic return conductor may be provided as part of the dc line.DC Lines.They may be overhead lines or cables. Except for the number of conductors and spacing required, dc lines are very similar to ac lines.AC Circuit Breakers.For clearing faults in the transformer and for taking the dc link out of service, circuit-breakers are used on the ac side. They are not used for clearing dc faults, since these faults can be cleared more rapidly by converter control.Useful Expressions in Passage BC:公司简介Guide To ProspectEver since its inception more than half a century ago, The Chang Sheng Electric Company has been making great strides under the motto “Create And Apply New Ideas.” The staff members of our company have been endeavoring for a higher living standard, and are dedicated to the improvement of society through the manufacture of unique products, electronic home devices and industrial equipment.Chronological History (1930—1985)1930Mr. Yu Zhao, president, establishes The Mao Yuan Company1940Production of AC tube radio begins.1946Assembly conveyor system adopted.1950Plant established.1959Company renamed The Chang Sheng Electric Co., Ltd.1966TV production started.1970Engineering agreement concluded with CCTV.1973 Production-Tape Recorder, Radio-phnograph, Electronic Industrial & Medical Instruments begins.1977World-wide sales net work incorporated.Business OutlineAuthorized Capital US$14,200,000.00Issued Capital US$ 4,141,400.00Established April, 1930Incorporated May, 1959Head Office & Main Plant &Central Research Laboratory 10 Jiao Da East Rd., BeijingHsinchu Plant 100 Bai Yi Rd., BeijingBranches Shijiazhuang, Taiyuan, Guangzhou远景指南昌盛电气公司自从50多年前创立以来,一直本着“创造并应用新构想”的座右铭,而获得长足的进步。

natural saline, dust, etc. In dry weather, dirt and dust have high resistance, so the leakage current on the insulator surface is small, and the insulator is less dangerous. When humidity is high or there is drizzle, fog, etc., the dust on the surface will become wet so the surface conductance will be intensified; then the leakage current of the insulator will be increased and the flashover voltage will be greatly reduced. Figure 6.1 and Figure 6.2 show two insulators suffering from pollution flashovers.

negative-sequence current and trips the main breakers of the generator after a prescribed time. When loss of excitation occurs, reactive power (Q) flows into the machine, and if the system is able to supply this the machine will operate as an induction generator still supplying power to the network. The generator will oscillates slightly as it attempts to keep in synchronism. Relays are connected to isolate the machine when a loss of field occurs. 1. A typical scheme is shown in Fig. 12.3 in which separate differential circulating-current protections are used to cover the generators alone and the generator plus transformer. 典型方案如图12.3所示,其中相互独立的差动环流保 典型方案如图12.3所示, 12.3所示 护分别用于保护发电机自身和发电机-变压器组。 护分别用于保护发电机自身和发电机-变压器组。 9

restraining or bias coil is connected, as shown in Fig. 12.2 (a), which carriers a current proportional to the full system current and restrains the relay operation through fault currents. The corresponding characteristic is shown in Fig. 12.2 (b). This principle (circulating current) may be applied to generators, feeders, transformers, and busbars and provides excellent selectivity.

(第六章The modern society depends on the electricity supply more heavily than ever before. 现代社会的电力供应依赖于更多地比以往任何时候。

It can not be imagined what the world should be if the electricity supply were interrupted all over the world. 它无法想象的世界应该是什么, 如果电力供应中断了世界各地。

. 第一个完整的电力系统(包括发电机,电缆,熔断器,计量,并加载的托马斯爱迪生所建 -站纽约市珍珠街的历史始于 1882年 9月运作。

这是一个半径直流系统组成的一个蒸汽发动机驱动的直流发电机面积约 1.5公里至 59供电范围内的客户。

负载, 其中包括完全的白炽灯, 为 V 提供 110通过地下电缆系统。

在一个类似的系统在大多数大城市在世界各地运行数年。

随着马达的弗兰克斯普拉格发展在 1884年,电机负载被添加到这些系统。

这是什么开始发展成为世界上最大的产业之一。

在最初的直流系统广泛使用尽管如此,他们几乎完全被空调系统所取代。

到 1886年,直流系统的局限性也日益明显。

他们可以提供功率只有很短的距离从发电机。

为了保持发射功率损失(我 2 R和电压下降到可接受的水平,电压等级,必须长途输电高。

如此高的电压不发电和电力消耗可以接受的,因此,电压转换成为一个方便的手段的必要性。

在发展的变压器,法国和交流输电由 L. 巴黎戈拉尔和 JD 吉布斯导致交流电力系统。

年,第一次在北美交流传输线将在俄勒冈州波特兰之间威拉梅特大瀑布和实施。

. 这是一个单相线路传输功率为 4,000公里,超过 21 V系统的距离。

随着交流的发展多相系统由尼古拉特斯拉,成为更具吸引力的。

通过 1888年,特斯拉举行交流多项专利电动机,发电机,变压器和输电系统。

Chapter 6 Electric Power Systems第六章电力系统Section 1 Introduction引言The modern society depends on the electricity supply more heavily than ever before.现代社会比以前任何时期对电力供应的依赖性都强。

(现代社会对电力供应的依赖性是前所未有的。

)It can not be imagined what the world should be if the electricity supply were interrupted all over the world.如果全世界都停止供电,简直无法想象世界会变成怎样。

Electric power systems(or electric energy system),providing electricity to the modern society,have become indispensable不可或缺的component of the industrial world.电力系统(或电能系统)给现代社会提供电力,已经成为工业社会不可或缺的组成部分。

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 September1882.托马斯·爱迪生建造了世界上第一个完整的电力系统(由一台发电机、线缆、熔断器、测量仪表和负载构成),它就位于纽约市的明珠街发电站,该电站于1882年的九月投入使用。

Section 1 Introduction
Return
The basic requirement to a power system is to provide an uninterrupted energy supply to customers with acceptable voltages and frequency. Because electricity can not be massively stored under a simple and economic way, the production and consumption of electricity must be done simultaneously. A fault or misoperation in any stages of a power system may possibly result in interruption of electricity supply to the customers. Therefore, a normal continuous operation of the power system to provide a reliable power supply to the customers is of paramount importance.
Section 1 Introduction
In the 1890s, there was considerable controversy over whether the electric utility industry should be standardized on DC or AC. By the turn of the century, the AC system had won out over the DC system for the following reasons: (1)Voltage levels can be easily transformed in AC systems, thus providing the flexibility for use of diቤተ መጻሕፍቲ ባይዱferent voltages for generation, transmission, and consumption. ( 2 )AC generators are much simpler than DC generators.

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。

按照汽轮机的热力特征分类 (1)、凝汽式汽轮机:蒸汽在汽轮机内膨胀做功以后,除小部分轴封漏气外,全部进入凝汽器凝结成水的 汽轮机.实际上为了提高汽轮机的热效率,减少汽轮机排汽缸的直径尺寸,将做过功的蒸汽从汽轮机内 抽出来,送入回热加热器,用以加热锅炉给水,这种不调整抽汽式汽轮机,也统称为凝汽式汽轮机. (2)、抽汽凝汽式汽轮机:蒸汽进入汽轮机内部做过功以后,从中间某一级抽出来一部分,用于工业生产 或民用采暖,其余排入凝汽器凝结成水的汽轮机,称为一次抽汽式或单抽式汽轮机.从不同的级间抽出 两种不同压力的蒸汽,分别供给不同的用户或生产过程的汽轮机称为双抽式(二次抽汽式)汽轮机. (3)、背压式汽轮机:蒸汽进入汽轮机内部做功以后,以高于大气压力排除汽轮机,用于工业生产或民用 采暖的汽轮机. (4)、抽汽背压式汽轮机:为了满足不同用户和生产过程的需要,从背压式汽轮机内部抽出部分压力较 高的蒸汽用于工业生产,其余蒸汽继续做功后以较低的压力排除,供工业生产和居民采暖的汽轮机. (5)、中间再热式汽轮机:对于高参数、大功率的汽轮机,主蒸汽的除温、初压都比较高,蒸汽在汽轮机 内部膨胀到末几级,其湿度不断增大,对汽轮机的安全运行很不利,为了减少排气湿度,将做过部分功的 蒸汽从高压缸中排出,在返回锅炉重新加热,使温度接近初始状态,然后进入汽轮机的的低压缸继续做 功,这种汽轮机称为中间再热式汽轮机.
