A Summarization of Research on Fault Current Limiter of Power System

In this paper the present situation of the research and development of power system fault current limiter (FLC) are summarized; the main classifications and features of FCLs as well as the implementation of economic FCLs with different current limitation modes are presented. The key problems to be solved in the practicability research of FCL, including the interactive impacts between FCL and the whole performance of power system, the interactive impacts between FCL and key equipments of power system such as generators, circuit breakers, protective relayings, economic evaluation of FCL, optimal design of FCL and on-line state detection of FCL, etc., are summed up. The advance of authors’ research on the new practicable design scheme for ZnO arrester based FCL and its application study are introduced.
