换流站广泛采用交流滤波器进行谐波滤除和无功补偿.交流滤波器内C1电容器不平衡电流过大成为了一个严重影响换流站投运调试进度和交流滤波器不平衡保护动作后设备故障处理时间的重要因素.传统的调整方法只能靠经验和趋势来判断,调整电容器单元的工作量大.本文结合±500kV永仁换流站调试实际,提出一种行之有效的不平衡电容调整方案.建议在C1电容器两端加一序列电压，低压端接地，将不平衡CT两端引流线接入，利用电流表测量CT二次侧电流。同时将周围交叉跨越的线路停运，避免电磁干扰。采用该方法可有效避免调整过程中不平衡CT对地电容和高压母线电磁感应对调整结果的影响,可以显著提高电容调整的效率.工程实际也验证了推荐方案的有效性.
