摘　　要：定量划分各主要谐波源在特定母线上的谐波责任是电能质量管理的一项重要任务。该文从理论上证明了谐波电流责任指标与谐波电压责任指标是不一致的,考虑到电网责任,选择谐波电压责任指标来衡量谐波污染责任。考虑到目前电网电能质量监测系统只提供电压、电流统计值的实际情况,提出了一种基于电能质量数据交换格式下的谐波污染责任定量估计算法。与传统的基于瞬时值的谐波污染责任划分方法不同,提出的方法可以利用目前的电能质量监测系统实现日常的谐波污染责任监测。Quantitatively determining the harmonic contributions of main harmonic sources to specific bus is an important task of power quality management. The authors prove theoretically that the contribution index of harmonic current does not conform to the contribution index of harmonic voltage. Considering the liability to be borne to power grid, the contribution index of harmonic voltage is chosen to weigh the liability for harmonic pollution. Considering the actual condition that current power quality monitoring system only provides statistical values of voltage and current, a power quality data interchange format based quantitative estimation algorithm for the liability of harmonic pollution is proposed. Different from traditional instantaneous value based division method for the liability of harmonic pollution, the proposed method can utilize current power quality monitoring system to implement daily monitoring for the liability of harmonic pollution.
