This paper analyzes the design and simulation of vector oriented control of three-phase voltage source pulse-width modulation (PWM) inverter which aims to optimize the utilization of wind power injected into the grid. To realize this goal, a digitally controlled converter-inverter system is proposed which provides economical utilization of the wind generator. In order to examine the dynamic performance of the system, its model is simulated and results are analyzed. The simulation results are given using MATLAB7/SIMULINK program. The results for different disturbance conditions show good performance of this proposed control algorithm.
