Analysis of reactance-type superconducting fault current limiter to the transient stability of power system with two machine system

摘要

In view of the short circuit fault of two machines, the influences of superconducting fault current limiter (SFCL) to power system with two machine system is studied. Through analyzing the curve of the minimum of relative acceleration of a model system with adding reactance, the influence rule of SFCL to Power System transient stability. The time-domain simulation of transient stability is carried out to verify the analytical results.
