Abstract：Fault Current Limiter is an overload protection device which can effectively limit the short circuit current. In this paper, the classification and existing problems of the fault current limiter are briefly introduced, and an energy-saving fault current limiter based on fast switching technology is proposed. The key technology of this kind of fault current limiter is expounded in this paper, and the Matlab/Simulink simulation is used to analyze the current limiting effect under different short circuit faults. Finally, This paper compares the economic performance of traditional fault current limiter and energy saving fault current limiter, carries out cost analysis, and demonstrates the energy saving effect of energy saving fault current limiter by using calculation examples.
