摘　　要：在理想或不理想的电压供应下,由于电力系统中非线性负载和无功功率补偿产生的谐波电流,提出一种设置有源电力滤波器的参考补偿注入电流控制策略。基于dq变换及占空比控制策略的有源电力滤波器能检测到谐波电流并进行补偿,Simulink仿真表明提出的控制策略能补偿谐波电流和保持电流源的正弦性。A novel control strategy for determining the active power filter（APF） reference compensation current injections to control harmonic currents generated by nonlinear load and reactive power compensation under ideal or nonideal supply voltages is presented in the paper. Duty-ratio control strategy based on dq transformation for APF is proposed,in which the harmonics current and reactive current are taken into account. Results obtained by Simulink show the advantages of the suggested approach：effective on compensation harmonic current and to maintain the currents source sinusoidal.
