摘要
针对500kV变电站并联电容器组电压差动保护启动回路运行中存在的问题,以保北500kV变电站为例,分析电容器组配备三套管式放电绕组和电容器组配备双套管式放电绕组的改造方案及改造效果,并针对如何克服电压差动保护的局限性提出建议。
Under operation problems of differential voltage protection starting circuit in 500 kV substation shunt capaci-ty bank ,taking Baobei 500 kV substation as instance ,this pa-per analyzes the reformation projects for three tubular dis-charge winds ,and double tubular discharge winds for capaci-ty banks ,illustrates reformation effects ,and advises on how to overcome the limitations of voltage differential protection .
