摘　　要：为正确识别电力系统公共连接点处的主要谐波源,基于IEEE 1459功率标准定义的谐波视在功率,提出了一种基于该功率指标进行判断的主谐波源识别的新方法。根据叠加定理分别定义系统侧和用户侧等值谐波源单独作用时引起的谐波视在功率,通过直接对比二者的大小,判断出主谐波源的位置是系统侧或用户侧。提出的方法可以考虑各次谐波电压、谐波电流的综合影响,进而识别出公共连接点处综合主要谐波源。最后通过IEEE 13节点系统仿真和某钢铁企业实测数据均验证了所述方法的合理性。Correct identification of the harmonic source is important for harmonic responsibility sharing and mitigation. A single-point identification method of harmonic source is proposed based on the concept of harmonic apparent power recommended by IEEE 1459. According to the superposition theorem, the harmonic apparent power caused by the system side and the customer side is defined separately, then the location of the dominating harmonic source can be determined （the system side or the customer side） by directly comparing the sizes of the two values. This method can consider the combined influence of multiple orders of harmonic voltage and current. Simulation on an IEEE 13-bus test system and actual steel plant test has verified the rationality of this method.
