电容电流超标变电站的弧光过电压幅值及影响因素研究

open access: yesDianci bileiqi
近年来我国配电网电容电流逐渐增大,中性点消弧线圈容量面临限制,无法保证可靠熄弧。对电容电流超标的中性点不接地配电网中弧光过电压的幅值和影响因素进行研究,有助于评估过电压威胁,提出合适的大电容电流配电网的中性点接地方式,实现高准确率的单相接地故障识别和选线。基于我国配电网的发展历程,搭建了几种具备不同出线参数的大电容电流10 kV变电站模型,仿真计算不同故障工况下的弧光过电压幅值,其中考虑包括故障点过渡电阻、故障点位置和电容电流等在内的共6个因素的影响。结果表明,电容电流超标的变电站不会出现幅值高于3.5
