Development of High Temperature Superconductor Current Limiter

摘要：

Short current limiting technology is a hot problem in power grid with short current increasing. Several short current limiting technologies are analyzed. And improved bridge-type superconductor current limiter which can limit instantaneous and steady short current is presented. Resistance-type, bridge-type and improved bridge-type superconductor current limiter are simulated. Scheme and parameters are proposed, based on which we develop a 10 kV hightemperature superconductor current limiter. In Aug. 14th, short testing implements at Gaoxi 110 kV power station in Loudi bureau, Hunan Province. Later, the limiter runs in the power grid. In short testing, the limiter can prevent the short current from 3500 A (Vms) to 635 A(Vms). There is no saltation in wave. The superconductor current limiter has run six month and all indexes are well-balanced. All these can make a base for superconductor current limiter large-scale application.
