In order to improve reactive power compensation and harmonic compensation in power systems
This paper presented a control strategy model with variable structure for shunt active power filter based on the analysis of shunt active power filter principle.The state equations for variable structure control were established
and the switch function was set up.This stratigy gains excellent reactive power compensation and harmonic compensation due to implementation of closed-loop tracking control of power source current.The experiment and simulation results confirm its validity and feasibility.
