According to the topology of shunt active power filter, a novel current prediction method is put forward in this paper. The method is based on the principle of deadbeat control, which combines linear prediction and adaptive method. The method realizes accurate prediction of command current, and solves the time delay error in APF generated by digital control. As a result, it improves the real-time performance of harmonic detection in the system, and obtains reliable reference voltage vector. The real-time compensation of harmonic current is realized by applying SVPWM control method. Finally, the simulation model is built in Matlab/Simulink environment with relevant parameter settings. Simulation results prove the validity and effectiveness of the prediction method.
