换流站交流滤波器场鸟害故障原因分析和解决措施

换流站交流滤波器场内的高压电容器为塔层结构,一旦有鸟飞入可能导致层间放电造成电容器不平衡保护动作。通过对交流滤波器不平衡保护动作的内部原因和外部原因进行分析,提出增加电容器塔层间绝缘裕度、增加交流滤波器驱鸟设施的方案,全方位预防治理鸟害,为其他换流站(变电站)提供参考和借鉴。

Analysis and solutions of typical bird damage fault in AC filter field of converter station

The high voltage capacitor in the converter station is the tower structure, and when a bird fly in, it may cause the capacitor unbalance. Through internal cause and external cause analysis of the AC filter imbalance protection actions, the schemes were put forward for increasing capacitor tower layer insulation margin, shooing away birds devices of AC filter to prevent the birds hazards.
