The Device Design Of Reducing The Vibration In Wind Turbine

Along with the country's economic growth and social progress, the energy consumption is being sustained growth. Therefore, the development of green energy has become a global agreement, In the long-term energy strategy. wind power is consider of clean and renewable energy which more and more attentions are being paid by countries all over the world. Globally speaking, with the situation that the rapid development of wind power, the United States and most countries of European Union have put forward that Taking the development of wind power as a preferred in using new energy. In China, the installed wind capacity of wind power has exceed the installed wind capacity of hydropower, now. The offshore wind power which is consider as the direction of development in wind market is pay more attention in the world. Along with china has established 16 national energy R&D centers, it will significance for changing our energy consumption pattern and ensuring our energy safety, it also good for realizing the reduction targets in 2020.The concept that wind turbines could increasing employment, reducing the emission and in the aspects of keeping energy-saving has been accepted gradually. The future of wind will be more fast and more healthy.Some problems (e.g., tower collapsed, bolted looseness etc) has been exposed in the process of use, with the expansion of wind market and the wind generators were more frequently used in our country. It restricts the development of our energy target in reduce the emission, low carbon and environment protection. The wind power equipment is elevated facilities which have its special structure, and it is restrict by its working condition. We can't reduce the vibration by measures that giving it the reinforcement or setting damping due to they are different with other elevated facilities. It is very significance that research on the safe operation of wind power.This paper is combined with the background of wind power development, we analyze the situation of wind power application and the progress that in wind power in the world, as well as some problems in application of wind. It is starting from the structure of wind power as well as its working condition. Tell you the mechanism of vibration. At the same time, the research on reducing the vibration of the wind power has been put forward, according to patent document"A New Method Of Reducing The Vibration In Wind Turbine Design", which professor Tang proposed, the mathematic model of the tower system was established. Then it propose a scheme that could reduced the tower vibration, by using the electronic simulation software TINA, according to the equivalent analogy between the mechanical systems and electronic systems. next, we got the modeling by CAD software UG software form the scheme, and we got the design parameters by the dynamics analysis and fem analysis, and then Rendering drawings . Finally, do experiments on the device which design by us and made in the factory , and whether the device have a good effect on vibration or not.
