摘　　要：文章采用电力系统谐波潮流计算程序来分析变电站的电流放大问题。通过对电力系统谐波电流的计算，判断变电站并补支路在不同参数配置方案下是否发生谐波谐振，从而为合理的参数配置提供理论依据。对桂花和滴水井变电站进行的计算表明。This paper adopts the method of power system harmonic flow calcuation to analyse the problem of harmonic amplification in electric substations. Through calculating the harmonic currents of the compensating condensors branches which are mutual parallel in the substations, we can judge whether the harmonic resonates or not in different cases of parameter configuration, and then the theoretical basis will be provided for the suitable parameter configuration. The calculations about Guihua Substation and Dishuijing Substation are carried out and the results show that the method proposed is correct and effective.
