Abstract

As a kind of new protection device, fault current limiter has been used in power system .When the fault occured in the circuit, the transient model based on FCL will have some influences on transient stability of power system, distance protection and voltage sag. The paper will study the mechanism of influence on power system, a new distance protection setting method proposed after FCL being input and using the models and simulations of PSCAD-EMTDC to test and verify FCL´s influence on voltage sag. Analysis and simulation validation demonstrate that FCL not only improves transient stability of power system, but also reduce the influence of distance protection, as well as restrain the voltage sag effective.
