Abstract

This article introduces the conception of initiative overvoltage protection.Through the dynamic simulation test

using TCSC hardware bypass mode of operation

which can restrict the overvoltage of the series compensation capacitance and reduce the short circuit current

has been studied.An effective control strategy is proposed to reduce short-circuit current and protect capacitor when short circuit fault happened in power system.
