Abstract


Wind is recycled energy source. Nowadays the wind energy gains more and more recognition under the stress of energy and circumstance. The wind resource of our country is plenty, which has big potential to be used. To develop wind electricity and water electricity is a long-term energy source policy our country.To build up a simulation model for wind turbine generator system is very important because of a lot of requirements, such as high dependability of electricity system. With the development of electricity operation system and more complicated control system, it is more important and necessary for testing the control system by a simulation model. Besides, simulation system can be a simulation "test" platform for the realization of control methods and adjustment of parameters. Therefore, the wind turbine generator system simulation model is built up in this thesis to simulate the operation characteristic and to judge if the parameters are reasonable. In a word the dynamic simulation system is necessary for the design, manufacture, protection, measurement of wind turbine system.This paper establish wind model, the wind turbine rotor model, drive trains model, induction machine model, the electric power electron parts of wind power generation model, Then using soft of MATLAB, we realize the simulation. It introduces the control technology of wind turbine, mainly including variable blade pitch and variable speed control of wind turbine.
