摘　　要：介绍了一种新型的基于磁通补偿的故障电流限制器的工作原理。在电力系统正常运行时 ,变压器主磁通被补偿为 0 ,故障限流器呈现很小的变压器漏阻抗 ,压降很小 ,对电力系统运行无影响。当电网发生短路故障时 。A new type fault current limiter based on flux compensation is introduced. According to the transformer's equivalent circuit, the value of the current injected to the transformer's secondary winding is controlled so that the value of transformer impedance in power system can be controlled. When there is a large fault current in power system, the transformer will present high impedance to limit the fault current.
