Simulation Study of Shunt Active Power Filter Based on Compound Control
Shunt active power filter has been proved an effective means to compensate distorted currents caused by nonlinear loads in power distribution systems.Aiming at the limitations of PI controller in shunt active power filter
this paper adopts proportional integral control and repetitive control algorithm to correct the output current waveform of the shunt active power filter.Considering the main circuit structure of shunt active power filter
the harmonic measurement method based on instantaneous reactive power theory and the compound control strategy based on proportional integral control and repetitive control are proposed.Moreover
the proposed control strategy is validated by MATLAB/Simulink.
