In recent years, the electric power system becomes more and more complicated. Therefore, the supply of electric power with stability and high reliability is required. The increase of fault current has some possibility of causing step-out of generators and a large-scale blackout. Recently, the effectiveness of FCL (Fault Current Limiter) for suppression of fault current is examined. In this paper, Active type FCL which is carried out the on-off control after fault clearance is proposed. Computer simulations are carried out for 1-machine infinite bus standard model, and the system stabilization by active type FCL is confirmed.
