Research of an Improved Bridge Type Solid-state Current Limiter
As the expanding of power system capacity, the technologies of short circuit current limiting in power systems have been concerned greatly. This paper introduces a novel bridge type solid state current limiter and a new control strategy is proposed. The characters and operating principle of a novel bridge solid-state current limiter has been developed in detail. Simulation based on Matlab/Simulink is analysed and a laboratory set-up in which the thyristor is controlled by a single chip computer is tested. The results show that the FCL mode is successful in both computer simulation and laboratory test in limiting the fault currents.
