摘要：
Active Power Filter (APF) can significantly compensate the current harmonics produced by nonlinear loads. To do this feature, harmonic detection reference current generation play vital role. Direct Power Controller (DPC) has great harmony with instantaneous power compensation (PQ) algorithm as well as the ability to eliminate internal current loops. In addition, DeadBeat Controller (DBC) has high compatibility for digital implementation, superior control performance and fast dynamic response. However, DBC suffers from time delay linked to control action calculation and digital implementation. In this paper, a new deadbeat-based DPC method is proposed firstly to generate reference current and control of APF. Secondly, a simple and robust compensation method is proposed to eliminate aforementioned deadbeat delay thanks to the online/offline predictions. Several simulations are conducted in MATLAB/SIMULINK verified by experimental tests obtained from a DSP-based active power filter to illustrate the effectiveness and superior performance of the proposed control method. By employing the proposed control method, the Total Harmonic Distortion (THD) of grid current is decreased from 22% to 3% under steady state condition. While the dynamic response with proposed delay compensation validates significant transient response improvement.
