摘要:
过电压下开关柜内电弧仿真对于开关电器设计与改造有重要意义。本文通过EMTDC/PSCAD对变电站投切并联电容器的仿真计算,考虑了不同重燃方式的影响,得到了开关柜内过电压波形。并在MALAB/Simlink建立基于Mayr-Cassie模型的电弧模型,通过对不同过电压下的电弧模拟仿真。得到了在过电压下电弧的电压、电流曲线。计算结果表明:模型能良好的反应过电压下电弧重燃的外部特性。

Abstract: Arc simulation under overvoltage in switchgear has great significance to its design and retrofit. This article simulated the thyristor switched capacitor in transformer substation by EMTDC/PSCAD, in which, different way of restrike was considered and overvoltage waveform was obtained. The arc model based on Mayr-Cassie model is estab- lished in MATLAB/Simlink. Through the simulation of different way of overvoltage, the voltage curve, current curve of arc is obtained. The simultaneous result shows: the model could reflect the external character of arc restrike under overvoltage.
