Abstract

To control the switching overvoltage caused by switching off shunt reactor in 35 kV system

simulation and evaluation with the software ATP-EMTP

10 kV laboratory test

and on-site test in 35 kV system were conducted to investigate the control of switching overvoltage. The treatments

such as circuit breaker switching at the side of neutral point of shunt reactor

and paralleling MOAs via shunt reactor

were verified through field experiments. The results indicate that the circuit breaker switching at the side of neutral point of shunt reactor can control the switching overvoltage effectively. In addition

the validity and applicable range of other treatments are discussed.
