提高电容器组平衡配置效率的方法

To Improve the Method of Capacitor Group Balanced Allocation Efficiency

在分析超高压直流输电系统中交流滤波器电容器组平衡配置方法的基础上,针对采用传统的调整方法或者采用不平衡电流补偿方法,都无法避免调整耗时长的问题,提出了一种利用程序快速计算平衡配置,改变电容器组先安装后调整的传统施工方法,用以减小不平衡电流对保护装置的影响,从而提高保护的灵敏度并缩短调试工期。现场试验结果也证实了这种方法行之有效。

Based on the analysis of the HVDC system AC filter capacitor bank balance configuration, u^sed the traditional adjustment method or the method of unbalanced current compensation, can not avoid the problem of long adjustment time, proposed a utilization program quickly calculate the equilibrium configuration, changed the traditional construction method（adjustment after installation） of capacitor group, to reduce the unbalance current protection device, thereby enhancing sensitivity of protection and shortening debug duration. Field test results confirm that the method is effective.
