Abstract :
In this paper, a new fuzzy logic based control strategy is proposed to limit the fault current in distribution systems which include distributed generation units. In the normal mode of operation, the series compensator acts as a line compensator. As soon as the fault is sensed, the new control mode is activated to limit the fault current, and properly interrupt the breaker. Simulations performed in MATLAB/Simulink environment indicate that the proposed control strategy performs well to limit the fault currents of distribution systems and restore the voltage at the point of common coupling to its preset value.
