摘要
对于电力系统无功补偿来说,SVC是很重要的设备,对维持系统稳定和电压稳定方面有着非常重要的作用。TSC是SVC很重要的组成部分,对电容器投切控制和操作直接影响无功补偿的效果。TSC的电容器投切一直是问题,其要求投切可靠,响应迅速,同时没有冲击。针对上述要求,文章提出过基于晶闸管两端过零投切的投切方式,经过仿真和实验,能很好的解决TSC的投切问题。
SVC is an important equipment of power system to keep system stability and voltage staility.TSC is a main part of SVE,How to switch the capacitors is very important for the compensation effect,but it also is a difficult problem.The requirement follow： reliability,fast response and nonimpact.In this paper,the way of zero-cross triggering circuit is designed.The thyristor is not triggered until its voltage equal zero.The performance of zero-cross triggering technology can solve the problem and is proved by a lot of experiments.
