摘　　要：为改善有源电力滤波器对谐波的补偿效果并增大补偿范围,提出了在并联一个高通无源滤波器的同时,在控制系统中引入控制延迟补偿模块;通过高通滤波器来抑制高次谐波,增大其补偿范围,通过控制延迟补偿模块来改善对低次谐波的补偿效果;阐述了控制延迟补偿的原理和算法。仿真分析结果表明了该方法的有效性。To improve the compensation result of harmonics by active power filter （APF） and enlarge its compensating range, it is proposed to lead a control delay compensation module into the control system of APE in the mean time a high-pass reactive filter is connected in parallel with the APE By use of the high-pass filter the higher-order harmonics are restrained and the compensating range is enlarged, and the compensation result of low-order harmonics is improved by control delay compensation module. Here, the principle and algorithm of control delay compensation are expounded. Simulation results show that the proposed method is effective.
