Research on Simulation of the Shunt Active Power Filter with Hysteresis Comparison Control

摘要

The Study on digital and advanced control strategy for electric devices is in the ascendant With the development of electronic technology,a wide range of electrical products inject much harmonic pollution to the power grid. Therefore,the study on active power has become a hot issue. The hysteresis comparison control which is one of common current control methods on Active Power Filter is considered in the paper. The principle of the shunt active power filter, the hysteresis comparison control and the ip — iq harmonic detection method which based on instantaneous reactive power theory are shown detailed. And simulation is set up in Matlab/simulink,and then these simulative results are contrasted and considered. The simulation results also show that the hysteresis control active power filter,the waveform improved significantly.
