第一章第一节电力系统基本结构Part 1 Basic Construction of Electric Power SystemBasic Concepts of Electric Power System电能是一种理想的能力形式,便于传输和使用,而且很清洁,对环境和大气无污染,因此自被发现以来,电能发展迅速并且利用广泛。
电能的产生、输送和消耗过程就在这一被称为电力系统的整体化系统中实现。
Electricity is an ideal energy form, which is convenient to deliver and use, and is clean without polluting our environmentand atmosphere. The generation, delivery and consumption of electricity are realized in an integrated system which is calledelectric power system or power system.一个电力系统包括三个基本部分:发电系统、输电系统和配电系统,如图1-1 所示An electric power system consists of three principal divisions: power generation, power transmission system, and powerdistribution systems, as shown in Fig.1.1图1-1 电力系统的三个基本部分用户从电力系统取用的所有电能都是在某种形式的电厂(或者称作电站)中产生的。
发电是整个电能利用过程的第一环节。
All the electricity the consumers take from the power system is generated in a power plant, or called power station, of somekind. Power generation is the first stage of the whole progress of the utilization of electric energy.输电系统连接发电和配电系统,并经过网络互连通向其他电力系统。
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。
Passage 1Have you ever seen a moon that looks unbelievably big? 你曾经见过令人难以置信地大的月亮吗?1. To what do we compare the size of the harvest moon? (all of these)我们用什么与丰收月比较大小?(所有这些)2. The main purpose of the article is to( inform.)这篇文章的主要目的是(告诉。
)3. The author knew most people find the moon( mysterious.)作者知道大多数人发现月亮(神秘的)。
4. The moon looks bigger if (it is near the horizon)月亮看起来更大如果(它是在地平线附近)5. The autumn moon (helps farmers see as they harvest their crops).秋天的月亮(帮助农民看到他们收割庄稼)。
Passage 2 Strange thing happens to time when you travel. 奇怪的事情发生在你旅行的时候。
1. The best title for this selection is(How Time Changes Around the World).本文最佳的标题选择是(时间在世界各地如何改变)。
2. The difference in time between zones is (one hour).区域之间的时间差是(一小时)。
3. From this selection it seems true that the Atlantic Ocean (is divided into five time zones).从这个选择来看似乎是真的,大西洋(被划分为五个时区)。
A decrease in the field current gives rise to lagging (inductive) current in the stator; and increase in the field current that overexcites the motor causes a leading (capacitive) current to appear in the stator.励磁电流减小时,定子电流感性增强;励磁电流增加使电机过励时将在定子中产生容性电流。
An induction machine is an AC two-winding unit in which only one (primary, usually the stator) winding is supplied with an alternating current at a constant frequency ω1 from an external source.感应电机是一种具有双绕组的交流电气设备,它只有一个绕组(一次侧,通常是定子)通过外电源输入固定频率为ω1的交变电流。
Current transformers for protection are essentially similar to those used for the operation of ammeters, watthourmeters and other instruments.保护用电流互感器基本上同操作用的电流表、电能表和其他仪器类似。
DG planning also involves arranging for connection of the renewable power generator with the local grid, and for support of any local electric load when the renewable source is not available.分布式发电规划还包括安排可再生能源发电机与地方电网相连接,这样当可再生能源不可用时,本地电力负荷仍能得到支持。

The attraction of different people.2.The purpose of the last paragraph is to give a summary of the wholepassage.3.Why do truck drivers like a diner?It’s a haven against loneliness.4.Diners rattact many different kinds of people.5.Diners are fascinating.Passage 4 Doctors have known for a long time that extremely loud noises 1.Doctors have long known tha t one may lose his hearing when he hears aterribly loud noise.2.This passage suggests that one’s hearing will be damaged even if he hasheard a loud noise for only little more than one second.3.According to this passage, one conclusion you can draw is that aspirinmakes hearing damage from loud noise worse.lions of Americans are in danger of suffering hearing loss because theytake too much aspirin.5.The purpose of the experiment the American scientist did was to findwhether aspirin would increase the temporary hearing damage from loud noises.Passage 5Just two months ago, Ana, a teenager, was preparing for1.Ana realizes that she must do well on the exam .2.Ana has been studying English for seven years.3.Ana experiences difficulty with the professor’s lecture s.4.Ana tells the interviewers about her family.5.The best main idea for the first paragraph is Ana comes through with flyingcolorsPassage6 Any mistake made in the printing of a stamp raises its value to stamp collectors.1.A postage stamp’s value to colle ctors is raised if a mistake is made in theprinting.2.In 1847 most countries of the world were not yet using postage stamps.3.In 1847, the mistake on the locally printed postage stamps was in thewording4.$16800 is the collector’s value of the Twopenny Blue.5.The valuable stamps were designed by British printers.Passage 7 The communications explosion is on the scale of the rail, automobile or telephone1.By saying that he takes may images of his children, the author wants todisplay the influence of communications on life .2.The author most probably thinks the communications dust is amazing.3.Which of the following statements about the low-orbit satellites is true?The low-orbit satellites would replace towers and poles functionally.4.According to the passage, an optical-fiber audio-video link can enable us totalk and see each other no matter where we are.5.The phrase “each one”(Line2, para.5) can be best replaced by each car.

例如:在日常英语中表示“力量、权力”和在机械专业表示“动力”的power,数学上表示“幂”,在电力专业领域可以仍作为名词,表示“电力、功率、电能”;也可以作为动词,表示“供以电能”。
在日常英语中表示“植物”的plant,在电力专业领域中用来表示“电厂”等。
2.由日常英语词汇或其他学科的专业词汇,直接合成新的词汇。
例如:over和head组合成overhead,表示“架空(输电线)”;super和conductor 合成superconductor,表示“超导体”等。
3.由基本词根和前缀或后缀组成新的词汇。
大部分专业词汇属于这种情况。
