摘要
对某220 kV变电站35 kV并联电容器爆炸事故进行了分析,利用电磁仿真软件PSCAD/EMTDC对故障波形进行了复现,并对故障过程进行了分析。为避免发生类似事故,在35 kV母线电压互感器安装了非线性消谐装置,投切35 kV母线和电容器组正常,抑制铁磁谐振效果良好。
This article analyzes a 35 kV shunt capacitor explosion accident by using electromagnetic simulation software PSCAD/EMTDC. In order to avoid this kind of accident, the nonlinear harmonic elimination device is installed at the 35 kV PT neutral point. The 35 kV bus and capacitor are in operation successfully, and it shows a good effect on the ferromagnetic resonance suppression.
