Abstract
The fault current limiter can effectively limit the fault current level in a very short period of time,so as to prevent excessive short-circuit current from causing potential harm to the safe and stable operation of the power system and electrical equipment.It has become a key equipment to suppress short-circuit current in the power system.In this paper,the working principle of the fault current limiter is summarized firstly.Then,the influence of the installation position of the fault current limiter on the busbar differential protection under different main wiring modes is discussed in depth.The research results show that the action of the fault current limiter may reduce the sensitivity of the busbar differential element.Through the scientific and reasonable arrangement of fault current limiter and the reasonable setting of differential restraint coefficient,it can effectively prevent the rejection of busbar differential protection and ensure the safe and stable operation of power system.关键词
