Study Of The Active Power Filter

The Active Power Filter, which can compensate simultaneously the harmonics and reactive power of non-linear loads, is good method to eliminate the harmonic pollution in power system. This paper discussed several methods for limiting the harmonics, and mainly introduced the basic knowledge of the active power filter. A method of inspecting the harmonics based on instantaneous reactive power is presented. This method can inspect the harmonic component and reactive power immediately. Based on this prototype, MATLAB, which is a simulated tool for power system, is used to prove it. Experimental results are presented to conform the effectiveness of the APR...
