Study on the Specific Harmonic Suppression of Active Power Filter

Abstract:

Aiming at the problems that the traditional active power filter (APF) which is with limited bandwidth and is difficult to realize zero steady-state error control, we use a strategy based on multiple synchronous rotating coordinate for each harmonic separation to achieve the detection of selective harmonic and proportion-integral (PI) control. Then it’s able to implement zero steady-state error compensation. After establishing the mathematical model of harmonic rotating coordinate for the APF, we proposed a simple strategy of current coupling and decoupling. The simulation results and the prototypes’ practical operations proved that the control strategy can compensate for the selective harmonic effectively and respond to the changes of the conditions in time. Meanwhile it has good characteristics in dynamic response.
