Section 2 Components of Power Systems 第2节电力系统的组成部分Modern power systems are usually large-scale, geographically distributed, and with hundreds to thousands of generators operating in parallel and synchronously. 现代电力系统通常规模大，地域分布，并与数百名，并同步在数以千计的发电机并联运行。

They may vary in size and structure from one to another, but they all have the same basic characteristics: 他们可能会有所不同的规模和结构从一个到另一个，但它们都具有相同的基本特征：（1）Are comprised of three-phase AC systems operating essentially at constant voltage. （1）是由三个三相交流电压恒定系统经营本质上。

Generation and transmission facilities use three-phase equipment . 发电和输电设施使用三个阶段的设备。

Industrial loads are invariablythree-phase; single-phase residential and commercial loads are distributed equally among the phases so as to effectively form a balanced three-phase system. 工业负荷总是三相，单相负载的住宅和商业之间平等分配的阶段，从而有效地形成一个平衡的三相系统。

存储器系统4-1 简介正如第一章所提及的那样，所有的微处理器都需要各种存储器，它可以分为ROM（只读存储器）RAM（随机存储器）两种，它们可以保持程序稳定运行和存放暂时使用的数据。

ROM和RAM的作用是当CPU 调用它们的时候高效的存储程序和数据并把它们快捷的释放出去，也就是，迅速的高效的被CPU读写。

有一些重要的指标来衡量一个村存储器的质量，例如存储容量，存取时间，功耗，可靠度和集成度，如下面所列举的一样，当为一个应用配置一个单片机系统时，这些参数指标必须自习考虑，1.存储容量一个存储器的存储容量是指这个存储器能够存储多少信息。

一个存储器的容量极限和它的集成度，分区以及位于存储器里单片机芯片的制造技术有关，或者与存储器本身有关。

字节，简写为B，通常被用来表示存储器的存储容量，例如100B（100字节），100KB(105字节)，100MB（108字节），100GB（10011字节）等等。

2.存取时间存取时间指的是写信息到存储器和从存储器写出信息所必需的时间。

存取时间的长短会影响微处理器的运行速度，一个半导体存储器的存取时间通常可以短至10-7。

3.功耗功耗指的是当存储器正常工作时消耗的电功率。

一般说来，功耗与微处理器的存取速率有关。

高访问速度需要较大的功率消耗。

在满足所需的运行速度的前提下，保持尽可能小的功耗是最好的。

维持功耗和运转功耗，这两个概念是用来表述存储器芯片功耗的。

第一个功耗指的是存储器被选通工作是的功耗，而另外一个是指存储器没有被选通时的功耗。

4.可靠性存储器的可靠性指的是存储器抵抗环境条件干扰的能力，例如电磁场，温度，湿度等等其它的因素。

这就是说由VLSI技术生产的存储器具有很高的可靠性。

5.集成度集成度指的是多少个同等的半导体管或基本存储电路可以杯集成到一块芯片上。

每个基本存储电路可以存储一位二进制信息，因此，这句话可被表述为“位/片”。

例如，27656型存储器的集成度是256KB/片。

电气工程及其自动化专业英语翻译．Electric Power Systems.The modern society depends on the electricity supply more heavily thanever before. It can not be imagined what the world should be if the electricity supply were interrupted all over the world. Electric power systems (or electric energy systems), providing electricity to the modern society, have become indispensable components of the industrial world. 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. 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 suppliedat 110 V through an underground cable system.. Within a few years similar systems were in operation in most large cities throughout the world. Withthe development of motors by Frank Sprague in 1884, motor loads were addedto such systems. This was the beginning of what would develop into oneof the largest industries in the world. In spite of the initial widespreaduse of DC systems, they were almost completely superseded by AC systems. By 1886, the limitations of DC systems were becoming increasingly apparent. They could deliver power only a short distance from generators. To keep transmission power losses ( I 2 R ) and voltage drops to acceptable levels, voltage levels had to be high for long-distance power transmission. Such high voltages were not acceptable for generation and consumption of power; therefore, a convenient means for voltage transformation became a necessity.The development of the transformer and AC transmission by L. Gaulard and JD Gibbs of Paris, France, led to AC electric power systems. In 1889, the first AC transmission line in North America was put into operation in Oregon between Willamette Falls and Portland. It was a single-phase line transmitting power at 4,000 V overa distance of 21 km. With the development of polyphase systems by Nikola Tesla, the AC system became even more attractive. By 1888, Tesla held several patents on AC motors, generators, transformers, and transmission systems. Westinghouse bought the patents to these early inventions, and they formed the basis of the present-day AC systems. 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）V oltage levels can be easily transformed in AC systems, thus providing the flexibility for use of different voltages forgeneration, transmission, and consumption.（2）AC generators are much simpler than DC generators.（3）AC motors are much simpler and cheaper than DC motors.The first three-phase line in North America went into operation in 1893．——a 2,300 V, 12 km line in southern California. In the early periodof AC power transmission, frequency was not standardized. This poses a problem for interconnection. Eventually 60 Hz was adopted as standardin North America, although 50 Hz was used in many other countries. The increasing need for transmitting large amounts of power over longer distance created an incentive to use progressively high voltage levels.To avoid the proliferation of an unlimited number of voltages, theindustry has standardized voltage levels. In USA, the standards are 115, 138, 161, and 230 kV for the high voltage (HV) class, and 345, 500 and 765 kV for the extra-high voltage (EHV) class. In China, the voltage levels in use are 10, 35, 110 for HV class, and 220, 330 (only in Northwest China) and 500 kV for EHV class . The first 750 kVtransmission line will be built in the near future in Northwest China. With the development of the AC/DC converting equipment, high voltage DC (HVDC) transmission systems have become more attractive and economical in special situations. The HVDC transmission can be used for transmissionof large blocks of power over long distance, and providing an asynchronouslink between systems where AC interconnection would be impracticalbecause of system stability consideration or because nominal frequenciesof the systems are different. The basic requirement to a power systemis to provide an uninterrupted energy supply to customers with acceptablevoltages and frequency. Because electricity can not be massively storedunder a simple and economic way, the production and consumption ofelectricity must be done simultaneously. A fault or misoperation in anystages of a power system may possibly result in interruption ofelectricity supply to the customers. Therefore, a normal continuousoperation of the power system to provide a reliable power supply to the customers is of paramount importance. Power system stability may bebroadly defined as the property of a power system that enables it to remainin a state of operating equilibrium under normal operating conditionsand to regain an acceptable state of equilibrium after being subjectedto a disturbance.. Instability in a power system may be manifested inmany different ways depending on the system configuration and operatingmode. Traditionally, the stability problem has been one of maintaining synchronous operation. Since power systems rely on synchronous machinesfor generation of electrical power, a necessary condition forsatisfactory system operation is that all synchronous machines remainin synchronism or, colloquially in step. This aspect of stability isinfluenced by the dynamics of generator rotor angles and power-angle relationships, and then referred to rotor angle stability译文：电力系统现代社会比以往任何时候更多地依赖于电力供应。
