Research on the protection strategy of open-circuit fault of controllable wiring in 1000kV switching-type controllable shunt reactor

Abstract

In term of switching-type controllable shunt reactor of ZHANGBEI to XIONG'AN ultra-high voltage (UHV) power transmission system, this paper study the character of open-circuit fault of controllable wiring in UHV switching-type controllable shunt reactor, the volt-ampere characteristic of open-circuit fault of controllable wiring is provided. Furthermore, this paper provided a method of the calculation of fault protection in open-circuit fault of controllable wiring, the simulation of RTDS is completed to prove its reliability effectiveness and accuracy.
