The Simulation Study of Shunt Active Power Filter in the Power System Harmonics Restraint

Article Preview

Abstract:

because of the existence of non-linear loads,they will be inpouring a lot of harmonic current to the power system,in order to restrain harmonic,we have to take relevant measures to restrain. This paper introduces three measures of harmonic restraint firstly, expounds the active power filter, and then it analyses the work principle and mathematical model of shunt active power filter , building three-phase shunt active power filter simulation model,; At last, using MATLAB simulation experiment ,the result shows that the shunt active power filter of harmonic detection algorithm and the control strategy are correct and effective , and also it has the important significance to the power system harmonic restraint.
