摘要
在电力系统中,采用晶闸管投切电容器TSC(ThyristorSwitchedCapacitors)的动态无功补偿装置中,晶闸管对驱动信号要求严格,驱动电路相当复杂。介绍了TSC无功补偿的电路原理图和固体继电器SSR(SolidStateRelay)的组成原理图及SSR的主要特点。考虑到过零型SSR具有TSC投切电容器所具有的过零触发功能,提出将其作为TSC的投切开关,从而简化了TSC电路。
For the dynamic reactive power compensation device applying the TSC（Thyristor Switched Capacitor） in power systems,the strict driving signal is required,making the driving circuit very complicated. The principle of the TSC reactive compensation is introduced,as well as the composition and main features of the SSR（Solid State Relay） are provided. Since the zero -voltage SSR has the zero-voltage triggering function needed by the TSC,it can be used as the switch of the TSC to simplify the TSC circuit.
