摘要
本文将含超导限流器的电力系统中的各种故障(各种简单故障和任意复杂故障)统一处理成对原网对称修正与不对称修正的组合,将含超导限流器的故障电力系统分解成两大部分:第一部分是变结构无故障对称网络部分;第二部分是模拟故障并计及超导限流器限流作用的不对称网络部分,在此基础上,基于补偿法和相序参数变换技术,提出了一种快速计算含超导限流器的电力系统中各种故障的通用方法。这种方法不但将含超导限流器的电力系统中各种故障的计算方法统一起来,而且对故障类型没有限制,还可适应因故障和超导限流器的限流作用而造成的电力系统网络拓扑结构的变化。
In this paper,any type of faults (simple or complex)in power system with Superconducting Fault Current Limiters(SFCL)are modeled as symmetrical or asymmertical modifications to each original sequence networks.Based on the compensation method,by using the phase-sequence parameter transformation technique and the multi-dimensional Thevenin theorem,a unified method is presented for fast calculation of any fault in power system with SFCL.This method can be adaptable to the network changes in topology caused by faults and SFCL.The method has been proved to be fast and accurate by a numerical example.
