Analysis and Simulation of Control Strategy of Three-phase Shunt Active Power Filter

The article first introduces the main circuit and the fundamental principles of three-phase shunt active power filter, and then analyzes the iP-iq current detecting algorithm based on instantaneous reactive power theory and also makes the comparative study on the two kinds of control strategies of hysteresis comparison and triangular carrier comparison, based on this, a simulation model of this filter is established and the simulations are implemented. The simulation results and the simulation test waveforms show that the method is of higher accuracy and availability.
