Generator Control System Research Based On The Wind Generator Variable Speed Constant Frequency Doubly-fed

In recent years, due to the countries all over the world demand for energy increases rapidly so as to promote the development of the acceleration of the process of industrialization. To face a major challenge for the sustainable development of social and economy and to solve the growing tension between the energy crisis and the worsening environment problem, has become the focus of people. Existing experts have estimated that from the beginning of the 21 st century the main clean energy we use included: hydropower, solar, nuclear, wind, etc. In many new energy and new technology, wind power has the characteristics of rich resources, clean environmental protection, have much attention.At present, the technology of the wind power industry in our country lack the most is the fan control system, basic rely on wind power more developed countries such as Denmark, Austria. Because of the lack of technology, resulting in our country so far has not for unified production in the country. But many of the workers in the fan in China are doing unremitting efforts, some enterprises and scientific research departments are carried on the thorough system of megawatt wind power unit of study.The wind turbine control system, this paper has carried on the basic research, set up a wind turbine variable pitch control system and yaw drive system mathematical model and simulation, the simulation results are analyzed and the research. When modeling and simulation using MATLAB/Simulink software, study of wind turbines variable pitch control system is using the data in the library. Simulation results show that build wind turbines variable pitch control system and yaw drive system on the algorithm while it is possible to meet the design requirements, but in the fan power output still lacked smoothness and stability. So in order to improve the stability of the model, in this paper, the fan variable pitch system and crab drive system has carried on the fuzzy control. From the point of the simulation results, does make the above two systems on the stability of improving, to improve the control system is designed.
