摘　　要：通过对三亚电网110kV鹿回头变电站10kV自动调谐调匝式消弧线圈投入后母线电压不平衡加剧实例,结合消弧线圈的工作原理及作用,从理论上分析电压不平衡加剧产生原因,并结合运行实际和相关规程规定针对此问题提出了相应的解决办法,使110kV鹿回头变电站10kV母线电压不平衡情况减弱,基本和未投入消弧线圈时一致且残流满足规程要求。Based on the example of bus voltage imbalance exacerbated when automatic tuning-turn-Petersen coil input on 110 kV power grid in Sanya Lubuitou 10kV substation and combined the working principle of Petersen coil, this papers analysis the theory increase of voltage imbalance causes. With the actual operation and related protocols, this paper presents corresponding solutions for this issue, so that bus voltage imbalance weakened and consistent with output of the Petersen coil and the residual flow to meet demand, which achieved marked results.

关 键 词：消弧线圈 不平衡 残流 脱谐度 改进措施
