The Coupling Research Between Wind Velocity Characteristics And The Dynamic Characteristics Of Wind Turbine

With the global depletion of conventional energy sources,many countries around the world are trying to find new energy sources.Currently, as one of the inexhaustible, non-air pollution, renewable energy, wind energy is one energy project of which many countries focus on the development.China is one of the few wind power, also a big energy consumption country.Therefore, the development of wind power is more and more pay attention to by the State.Currently, the Core Technology in our wind power projects are from abroad and Self-made technology is relatively low. Because of the uncertainty of wind speed, making the coupling between wind turbines from abroad and China's actual wind conditions be an important problem demanding prompt solution. After reading a great deal of relevant information both at home and abroad and investigating the overall development of wind turbine on the basis of our country at this stage,this article described the basic wind turbine theory,and established the speed model of Rudong county,Jiangsu province, and wind turbine model.At the same time, it based on Gamesa's production-type G60-2.0MW wind turbine at Yumen of Gansu,and part wind speed date of Rudong wind farm,in accordance with scientific and technological project of Lanzhou "Detection of large-scale wind power and monitoring feedback devices(Item Number:2008-1-16)" Then,this thesis used the simulation software to simulink and analyze the coupling between wind speed model.This thesis'research can provide theory of parameters and control methods for monitoring and feedback control system of the state of wind turbine which adapted to the characteristics of China's wind resources.This will enhance the country's large-scale wind turbine design quality, get more reliable control strategy and it plays an important role on digestion and absorption of the foreign wind turbine.
