摘要(Abstract)：

为有效评估系统侧和用户侧的谐波发射水平,提出一种采用稳健独立分量分析(robustindependentcomponent analysis,Robust ICA)的谐波阻抗估计及谐波发射水平评估方法。将公共连接点(point of common coupling,PCC)测量所得谐波电压与谐波电流数据的快速变化分量作为混合信号,通过稳健独立分量分析算法解混得到的独立信号与分离矩阵,利用诺顿等效电路方程的矩阵变换求解系统侧谐波阻抗值并进行两侧谐波电压发射水平的评估。利用Matlab软件基于诺顿等效电路及典型负荷曲线进行了仿真分析,验证了文中方法在不同背景谐波波动程度下均取得了优于传统方法的评估结果。工程实例应用亦验证了文中方法的正确性和实用性,具有较好的应用前景。
