The Simulation of Power System Transient Stability Enhanced by FCL

The Fault Current Limiter(FCL)model is presented first,and then the rotor equation is introduced in such different periods as normal state,three phase fault at the top of one line,when the FCL is workable and when the three phase fault has been cut off.With MATLAB,power system transient stability has been simulated respectively when the power system possesses FCL or does not possess FCL.It is concluded that the FCL can enhance power system transient stability.
