| Abstract: | 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 kV shunt reactor. |
