利用皮尔逊积矩相关系数分析方法将电网谐波电压畸变率与电网运行参数之间的关联性相结合，给电能质量数据分析与预警提供了一种新思路。分析计算结果表明，电网谐波畸变率与无功电容器组的投入量两者之间具有高度相关性。最后，基于分析结果对电网的无功电压优化控制提出了合理建议。

In this paper, Pearson product-moment correlation coefficient method is used to analyze the relationship between power grid harmonic voltage distortion ratio and power grid operation parameters, and a new way is given for power quality data analysis and early-warning. The study result in this paper indicates that there is highly correlation between the harmonic voltage distortion ratio and closing shunt capacitor banks. At last, the investigation results give useful suggestions for reactive power voltage automation control strategy.
