摘　　要：以西南地区某500 kV串补站电容器组不平衡电流频繁波动为例,通过分析不平衡电流度波动现象,排除干扰因素,找到不平衡电流度波动规律。根据电容器温度特性、设备结构、环境因素等找到不平衡电流度波动原因。Taking the frequent fluctuation of unbalanced current of capacitor bank in a 500 kV Series Compensation station in Southwest China as an example,by analyzing the fluctuation phenomenon of unbalanced current degree and eliminating interference factors,the fluctuation law of unbalanced current degree is found.According to the capacitor temperature characteristics,equipment structure and environmental factors,the causes of unbalanced current fluctuation are found.

关 键 词：串补电容器 不平衡电流 温度特性 光照影响
