摘　　要：基于黄南南部网架薄弱,短路电流过小导致电容器分组容量配置选择困难的问题,从电压波动、涌流倍数和谐振3个方面校验了2×3000 kvar、3×2000 kvar分组方式的可行性,并从经济角度提出了改变运行方式解决电压波动较高问题的建议。In order to deal with the problem of weak grid and selection difficulty of capacitor grouping capacity configuration caused by low short-circuit current in the southern part of Huangnan Zhou,the feasibility of 2×3000 kvar,3×2000 kvar grouping methods is verified from three aspects of voltage fluctuation,inrush current multiple and resonance.And suggestions to solve the problem of high voltage fluctuation by changing the operation mode are put forward from the perspective of economy.

关 键 词：电容器 电压波动 涌流倍数 谐振
