摘 要

随着我国工业化程度的加快,越来越多的大型无功设备用在工业现场,在这些机器使用的时候不仅消耗大量的无功功率,而且会产生大量的谐波污染电网。为了治理这些谐波污染,必须对系统进行无功补偿,无功补偿不仅可以稳定电压,消除谐波。而且还可以节约电能,这对能源匮乏的现实社会来说具有深远的意义。

本文主要做了一下几个方面的工作:

(1)介绍无功电源的种类,阐明了电力无功补偿的原理及作用。

(2)列举了静止无功补偿器的种类及其各自的优缺点,分析TCR型静止无功补偿器的工作原理,为TCR相关参数的确定提供理论依据。

(3)完成了TCR型SVC的晶闸管控制电抗器部分和并联电容器组部分的相关参数计算,为后面的仿真模块提供数据依据。

(4)采用MATLAB电力系统仿真软件,建立SVC仿真模型并进行仿真与研究。验证所设计的静止无功补偿器的无功补偿效果。

Power is an important energy, it is very important in our lives.

With the industrialization developing of China, more and more large reactive

power machines be used in industrial fields. Beside these machines not only

consume a large amount of reactive power, but also It will generate a lot of

harmonic pollution grid. In order to control these harmonic pollution, have to

reactive power compensation system can not only stabilize the voltage reactive

power compensation, harmonic cancellation. But also can save energy, which has

far-reaching implications for the social reality of energy shortages.

The Bachelor's Thesis done these following work:

(1)Describes the types of reactive power, Explanation the ruler of Reactive

power compensation.

(2)Show the kinds of Reactive power compensator,Pros and Cons.

(3)Calculate these parameters of TCR and FC.Provide the basis for the

Simulation.

(4)using MATLAB software to build simulation models for Power system.

Key words: Reactive power compensation, FC + TCR ,Simulation
