This project presents improvement technique for the power quality of the electrical part of a wind generation system with a self-excited induction generator (SEIG) which aims to optimize the utilization of wind power injected into the grid. To realize this goal, an uncontrolled rectifier-digitally controlled inverter (URDCI) system was proposed. The advantage of the proposed system is its simplicity due to less number of controlled switches which leads to less control complexity. The inverter system provides economic utilization of the wind generator by insuring unity power factor operation under different possible conditions. It also provides full control of active and reactive power injected into the grid using a digitally controlled voltage source inverter (VSI).
