Performance Analysis Of Shunt Active Filter Using Different Controllers
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 5
Abstract
In this paper, Performance of Shunt active power filter (SAPF) is analyzed for various types of non linear loads. Among the various control schemes available for SAPF, indirect current control scheme is used here. PI controller and fuzzy logic controller are used to analyze its performance for various types of nonlinear loads (R, DC motor, Induction motor). The output parameters are Total Harmonic Distortion (THD) and power factor. The results are obtained with the conventional PI controller and fuzzy controller. The proposed method offer an efficient control method under the various load conditions results in power factor improvement and THD reduction. Simulation of the proposed controller(PI and fuzzy logic controller) of a shunt active power filter has been carried out in MATLAB/SIMULINK and the aim is to reduce the THD and improve the power factor.
