| 摘 要： | 研究了中低压电网中由非线性负载产生谐波的机理，提出所有由非线性负载直接引起的谐波是电流谐波，因而治理非线性负载引起的谐波应首先考虑治理谐波电流。同时，从补偿和滤波两种思想出发，指出并联型谐波补偿有源电力滤波器(APF)的补偿作用和串联型基波补偿APF的滤波作用可适用于非线性负载谐波电流的抑制。仿真结果验证了理论分析的正确性。

| Abstract: | The mechanism of harmonic caused by nonlinear loads in power systems with medium or low voltage is analyzed. It is put forward that the harmonic directly caused by nonlinear loads is current harmonic, which should be suppressed firstly rather than harmonic voltage. From the idea of compensation and filtering, the parallel compensating harmonic APF and series compensating fundamental wave APF are suitable for suppressing harmonic current. The correctness of the analysis is verified by simulation results. |

| Keywords: | nonlinear loads harmonics characteristic active power filter (APF) characteristic of compensation and filtering |
