[Abstract]:Wind power generation relies on its unique characteristics, such as: environmental protection, green, cost-effective, simple development, rich resources and other innate advantages have been widely used and developed all over the world. Undoubtedly, it has become one of the most valuable renewable energy sources in the world. From the point of view of the current environmental pollution problems and the low energy use rate, the problems that will be faced in the future will become increasingly serious. This has aroused the enthusiasm of various countries all over the world for the development of renewable energy, especially in the wind power technology to constantly promote new goals and determination. In recent years, China's wind power generation industry has been booming, its installed capacity has doubled for several consecutive years, and the conversion efficiency of wind power generation has been improved, so as to maximize the conversion of wind energy into electric energy. One of the most important links is the research of wind power grid-connected technology. Compared with other types of hydropower plants, the difference between thermal power plants and wind power plants is that due to the uncertainty of wind power, the output power fluctuation of wind power is very obvious. In the large-scale wind power grid connection, there will be a series of effects on the grid, such as different degree, different scope and different scale, especially on the frequency and stability of the grid. Therefore, it is of great significance to carefully study and discuss the grid-connected operation of the wind power system, and take reasonable measures to ensure that the grid can operate more fully and stably after the grid connection. After the wind power grid is connected to the grid, it is of great significance. The real-time data acquisition and presentation of wind power data (such as wind speed, power generation, etc.) is of great significance to the research, maintenance and development of wind power. This paper mainly analyzes and designs the following aspects: discussing and analyzing the mainstream wind power generation system, which is widely used in the market at present. Based on the analysis and design of wind power model, a new type of wind power generating equipment with active pitch variation is designed. Then its composition and working principle are described, and then the reliability analysis of its mechanical performance is carried out. Then the circuit is designed and simulated with SI MULINK, and the simulation results are analyzed. Finally, a WEB system is built, which can acquire and observe the change of wind power data in real time. To the future wind power generation technology of the continuous introduction of new and do a little bit of force.
