摘　　要：谐波检测算法是有源电力滤波器的重点研究内容,算法的好坏直接影响有源电力滤波器的谐波检测及补偿效果。分析了三相瞬时功率理论并推导基于该理论的ip-iq谐波电流检测算法,在MATLAB/Simulink平台上建立了基于该算法的三相并联型有源电力滤波器的谐波检测模型,再结合滞环比较控制方式以及逆变电路,构建了有源电力滤波器的整体仿真模型,通过动态仿真对谐波检测、跟踪及补偿效果进行验证,结果证明该算法谐波检测效果良好,基于该算法的有源电力滤波器谐波补偿效果良好。Harmonic detection algorithm is very important to the research of APF as it will impact the effect of active power filter harmonic detection and compensation directly.A harmonic detection algorithm based on instantaneous-preactive-power theory is discussed,and a three-phase harmonic detection model which is established with MATLAB/Simulink software is also proposed.Combining with hysteresis comparison controlling system,an active-powerfilter simulation model is established,and the harmonic tracing,detecting and compensating effect is tested.The result shows that the algorithm is effective and the APF model based on this algorithm could compensate harmonic very well.
