摘要

通过引入可变电阻模型的方式

实现了电弧电阻模拟电弧电压的思路

在RTDS仿真环境中搭建了发电机断路器模型

并以该模型为基础

搭建了发电机源三相接地故障仿真网络。以具有最大非对称度的某相为例

分别仿真研究了发电机源三相接地故障后

不考虑发电机断路器开断过程中电弧电阻以及故障位置电阻时、仅考虑故障位置电阻时以及仅考虑发电机断路器开断过程中电弧电阻时

该相短路电流变化。最后

利用RTDS/RSCAD的Playback录波回放功能

分析比较了不同状况下的仿真结果

从而得出电弧对发电机断路器电源侧短路电流的影响。仿真结果可作为确定发电机断路器电源侧短路电流开断能力的参考依据。

Abstract

Through introducing the variable resistance model to simulate the arcing voltage by the arcing resistance

the generator circuit breaker model is built based on RTDS

on which the simulating network of three phase to earth faults in generator source is built up. Taking as the phase on which has the highest degree of asymmetry as example

the fault currents under the case of three phase to earth faults in generator source are simulated separately in different cases as following: without considering the arcing resistance of fault location and without arcing resistance of the generator circuit breaker during opening process; only with considering the arcing resistance of fault location; and only with considering the arcing resistance of the generator circuit breaker during opening process. Finally

using the Playback model in RTDS/RSCAD

the above simulation results are analyzed and compared in order to get the effects of the arcing on the short circuit current. This study may provide a reference for determining the short circuit current interrupting capability of the generator circuit breaker under the short circuit occurred in source side.
