摘要
介绍了东北伊冯 5 0 0 k V可控串补系统的一项 TNA试验中断路器甩负荷、解列、振荡解列和切除故障时的暂态恢复电压 ,短路电流的延迟过零现象和线路的操作过电压。试验中考虑了可控串补限压器、保护性旁路和线路避雷器的作用。对断路器的工作条件进行了检验 。
A TNA study of Yiming—Fengtun 500kV TCSC compensated system is presented, which includes Transient Recovery Voltage (TRV) of the circuit breakers, switching surges and non zero crossing phenomenon. The effects of the varistor, the protective bypass of TCSC thyristor as well as the line surge arrestor are considered. The working conditions of the circuit breaker in the system are verified and the additional initiative signals of the by pass control are proposed.
