Power Quality Improvement in Wind Energy System Using Seven Level Shunt Active Filter

Authors : K. Ramesh and G. Tholkappia Arasu

Abstract: This research concentrates on improving the power quality in Wind Energy System (WES) using 3-phase, Seven Level-Shunt Active Filter (SL-SAF). In this background, the Permanent Magnet Synchronous Generator (PMSG) based 2.5 kW WES is considered to implement SL-SAF. The main intention of this SL-SAF is to improve the power quality in the proposed system when WES output changes with the wind speed and also to the variation in load. Moreover, it reduces the power loss during low wind velocity and also due to Total Harmonic Distortions (THD) with improved power factor. In this research, the proposed system performance parameters like output voltage, frequency and THD levels are analyzed for various wind velocities and unbalanced load conditions. Furthermore, the validity of SL-SAF is analyzed with intelligent Fuzzy Logic based Pulse Width Modulation (FL-PWM) techniques. The MATLAB/Simulink Software tool is employed for analyzing the performance of the proposed system. From the simulation results it has been evaluated and the relative results are used to validate the parameters of the SL-SAF converter.
