A active power filter is an effective method for harmonic pollution compensation or offset to the electric network. The work principle for the active power filter system is theoretically studied and analyzed. SimPower work-box provided by MATLB/SIMULINK includes all the aspects of the modeling and simulation in power system. Use SimPower work-box to build the modeling and simulation to the active power filter. The method can make the work process of active power filter and the relative wave forms be shown accurately and directly. It proves the validity of theoretical analysis.
