摘要
结合工频熄弧理论,利用Matlab电力系统工具箱(PSB)建立10kV配电网仿真模型,对中性点不接地、经消弧线圈接地和中性点经小电阻接地三种接地方式下的弧光过电压现象进行仿真分析比较,指出了经消弧线圈接地方式是目前比较合理的接地方式,适应智能配电网建设。
Combined with the power frequency arc extinction theory, the lOkV distribution network is established by the power system toolbox (PSB) of Matlab software. The phenomenon of arc grounding over-voltage is analyzed based on three grounding types, including isolated neutral system, neutral grounding via arc suppression coil and neutral grounding via low resistance. It pointed out the arc suppression coil grounding method is a reasonable method that adapt to the construction of intelligent distribution network.
