The modeling and simulation of a grid-connected wind power system or WECS (acronym for Wind Energy Conversion System) has been carried out. Our goal is to design and test a power system of 14.9 KVA capacity, operating at 440V, 20m / s wind speed base, induction generator based on wind power system through. MATLAB simulation. The various components of a wind power system, namely wind turbine, generator, control system, rectifier-inverter, battery, load and other equipment, including transformers, network, etc., were Decided according to the scope of this project. The system in the MATLAB - SIMULINK simulation environment was carried out.

One of the most significant events of the late twentieth century was the resurgence of wind as a potential source of energy generation. An emerging awareness of the finite fossil fuel reserves of the earth, as well as the adverse effects of burning those fuels for energy had made many people look for alternatives. Growing concern about emissions from fossil fuel generation and increased government support has helped develop wind energy installation in India and abroad. The provision of incentives instituted by the Ministry of New and Renewable Energy (MNRE) has made wind power competitive in India. In India the current installed capacity is 14158.00MW until March 31, 2011. The need for power generation, potential and technological capacity were the reasons to encourage the emergence of wind energy.
