摘　　要：根据真空开关开断并联电容器组时的操作过电压产生机理并结合电力系统的典型电路和试验数据,使用Electro-magnetic Transient Program(EMTP)建立了能模拟这种过电压的计算模型,进行仿真计算,使用方便,可靠性和准确性高。According to the test data of the typical power system circuit and the mechanism of the switching overvoltage appearing when vacuum switches work to switch off shunt capacitors, the computational models were built by EMTP to simulate the overvoltage. They are easy to operate and have high reliability and accuracy.
