Abstract：The rapid development of power electronics technology, on the one hand to the transformation and application of electric power has brought convenience, on the other hand, has brought the power quality is a serious problem to the power system, such as harmonic pollution, no power, voltage fluctuation and unbalance. ActivePower Filter (APF) is one kind of modern power electronics equipment which can compensate harmonic current and reactive power. This paper chooses three phase shunt APF to study. The thesisbuilds simulation model of APF using Matlab software, and focuses on the harmonic.

In this thesis, the classification and basic working principle of active power filter are mainly introduced. The main circuit of the power electronic devices are selected through the way of calculating the main parameters of the active power filter.Several methods of measuring harmonic and reactive power current are introduced and compared in this paper and MATLAB is employed to make the simulation for ip-iq method .At the same time, the compensation of active power filter ip-iq method and scope of application are analyzed also. Finally, through the deadbeat control principle of active power filter based on Simulation, the deadbeat control principle of compensation current control can be analyzed.
