摘要
分析了操作过电压特点和产生原因。通过空载合闸线路时的集中参数等值电路对其产生的过电压进行计算,运用ATP-EMTP仿真对500 kV输电线因不同操作产生的过电压情况进行仿真试验,得到了断路器合闸空载线路过电压的特点,为过电压抑制措施提供了参考。
Characteristics and causes of the operating over voltage were analyzed. Through lumped parameter equivalent circuit of no-load closing circuit, its over voltage was calculated. ATP-EMTP simulation software was used to complete 500 kV transmission line＇s simulation due to different operating over voltages, getting the characteristics of no-load closing over voltage on vacuum circuit breaker , which provides a reference for the over voltage suppression measures.
