Abstract: Wind energy conversion system is a complicated field refers to electrical machine, power electronic, electrochemistry, material, mechanics, aerodynamics, computer, automation, aerograph and etc. Following the increasing demand of electric power and environmental protection all over the world, it is important to exploit the renewable and clean energy sources. First of all, an accurate WECS model with its control system is the base of all the following studies. In the dissertation, an integral WECS model is built using digital simulation software MATLAB. The simulation results show that the model present dynamic performance tallying with that of actual systems underany operation conditions.
Key words: Switching Power Supply; Inverter; Auto control.
