摘要

笔者提出了改进型桥路模型

该模型可限制瞬态短路电流和稳态短路电流。文中对电阻型、桥式和改进桥式超导限流器进行了仿真

提出了高温超导限流器的技术方案和技术参数

在此基础上研制了10 kV高压系统的高温超导限流器。限流器于2005年8月14日在湖南省娄底电业局高溪110 kV变电站进行了短路试验

并挂网运行。短路试验中

成功将3 500 A（有效值）限制到635 A（有效值）

且短路瞬间波形无突变。从6个月的运行经验来看

超导限流器各种运行指标良好

为超导限流器的规模应用奠定了基础。

Abstract

An improved bridge-type superconductor current limiter which can limit instantaneous and steady short current was presented

and the resistance-type

bridge-type and improved bridge-type superconductor current limiters were simulated.Scheme and parameters were proposed

based on which a 10 kV high-temperature superconductor current limiter was developed.A short testing of the limiter was conducted at Gaoxi 110 kV power station in Loudi bureau

Hunan Province

and later the limiter was used in the power grid.In the short testing

the limiter decreased the short current from 3 500 A（RMS） to 635 A（RMS） without wave saltation.The superconductor current limiter has run for six months and all indexes are well-balanced.All these can make a base for superconductor current limiter large-scale application.
