摘　　要：近年来我国频繁发生220 kV变电站35 kV并联电抗器切除时操作过电压导致的设备故障,危及电网安全稳定运行。对切除并联电抗器过电压产生的机理、危害和抑制进行系统分析,提出了并联电抗器的选相投切策略,并开展了现场过电压实测和PSCAD仿真分析,为35 kV并联电抗器操作过电压的抑制提供了解决思路和工程经验。In recent years,equipment breakdowns caused by overvoltage during 35 kV shunt reactor switching in 220 kV substations frequently occur in China,which endangers the safe and stable operation of power grid. The mechanism,perniciousness and suppression of shunt reactor switching overvoltage are systematically analyzed. The strategy of phase controlled circuit breaker is proposed,and the field overvoltage measurement and PSCAD simulation analysis are carried out,which provides solutions and engineering experiences for the switching overvoltage suppression of 35 k V shunt reactor.
