A novel fuzzy based pitch angle control scheme and SVPWM based active and reactive power flow control of a permanent magnet generator based grid tied Wind Energy Conversion System

This paper investigates a novel method to compensate the reactive power losses incurred in a wind energy conversion system equipped with maximum power point tracking. A variable speed generator is used here, which is a permanent magnet generator. In order to enable protection from mechanical damages of Wind Energy Conversion System, pitch angle control is employed which is an advanced pitch angle control strategy based on fuzzy logic. Also, the switching of inverter is done using Space Vector Pulse Width Modulation logic. Gate pulses for inverter are generated using SVPWM block. The simulation of the integration of a system to the grid with maximum power point tracking, fuzzy logic based pitch angle control and SVPWM based inverter switching is performed using MATLAB/SIMULINK software and the simulation results are also presented.
