Application of Slipped-Window Integrator and Repetitive Predictor in APF

Abstract:

In view of the shortages time lag existing in traditional digital low-pass filter in Active Power Filter (Active Power Filter, APF), this paper proposes to adopt slipped-window integrator to realize low-pass filter in harmonic current detection.The current tracking control uses Space Vector Pulse Width Modulation method. Meanwhile, the repetitive predictor is applied so as to improve the real-time performance of the compensation current tracking control. Built a three-phase shunt active power filter simulation model in Matlab/Simulink environment and take experiment under the low pressure condition. The results show that slipped-window integrator and deadbeat current mothod can acquire good dynamic response performance as well as high precision.
