Abstract

A fault current limiter with series compensation is presented for 10 k V distribution network system.It is composed of a capacitor and an inductance in series with main circuit

some metal oxide surge arresters in parallel with the capacitor

a damping loop

some anti-parallel thyristors

and a bypass switch.The topology and working principle of the fault current limiter are described

and its influence on single machine infinite system is analyzed theoretically.A simplified 10 k V distribution network model is established to investigate the influence of the fault current limiter on the power system’s transient stability via MATLAB/Simulink.Theoretical and simulation results show that the fault current limiter can improve the power quality and the capacity of transmission line in normal state

and it can limit short-circuit current to improve the transient stability of the power system in the case of short circuit.
