| 摘 要： | 桥式超导故障限流器,它由超导磁体、二极管桥路和直流偏压源组成。超导故障限流器与常规限流电抗器不同之处是:将其接入电网,当电力系统正常运行时,超导体电阻几乎为零,对电力系统运行无影响;当电网发生短路故障时,超导线圈可以无时延地被自动串入线路,从而限制了短路故障电流,使得轻型断路器可以正常动作。通过PSCAD软件对超导故障限流器的运行特性进行仿真分析,证明超导故障限流器在电力系统中应用的意义与前景。

| Abstract: | The limiter consists of a superconducting coil, a diode bridge and a bias voltage supply.The device presents no impedance to the current flowing through the power system during normal operation.Under short circuit conditions,the superconducting coil will be automatically inserted into the system and thereby limits the fault current,so that the underrated switchgears can be operated safely.To evaluate the performance of the superconducting fault current limiter(SFCL),the PSCAD analysis has been executed on a power system.Results shows that the SFCL could be used as a practical device in electric power systems. |
