摘要

首先分析了常用的几种晶闸管投切电容器装置（TSC）的主电路

以晶闸管与二极管反并联构成的TSC无触点开关为例

分析了TSC装置合闸过程中

晶闸管阀端可能承受的过电压

并提出了采用并联MOA抑制过电压的方案。以一组工程应用的10 kV TSC装置为例

采用matlab/simulink对装置采用MOA前后的过电压水平进行了仿真分析

结果表明

采用阀端安装MOA抑制过电压的方案是可行的。

Abstract

This paper analyzes the prime circuit frame diagrams of Thyristor switching capacitor（TSC） commonly used.And the possible overvoltage upon the thyristor valve during the closing process of TSC has been analyzed.A new method of restraining the overvoltage using the MOA has been advised.Based on a practically used 10 kV TSC device

the effect of restraining overvoltage of MOA has been simulated and analyzed using the software Matlab/Simulink.The simulating result indicates that it is feasible to restrain the closing overvoltage of TSC device by MOA connected in parallel with the thyristor valve.
