Description

Technical Field

[0001] The present invention relates to the field of new energy, and particularly to a method for rapidly evaluating the load adaptability of a wind turbine. Background Art

[0002] As one of the power generation methods with the most mature technology, the largest scale of development and the most promising commercial development prospects in the development of renewable energy, wind power generation has attracted more and more attention from countries around the world and has been widely developed and applied due to its outstanding role in reducing environmental pollution, adjusting the energy structure, and solving the electricity consumption problems of residents in remote areas. In recent years, the development of wind power generation has been booming, with the installed capacity of wind turbines doubling every year, and the safe operation structure of wind turbines has gradually become the focus of attention of wind turbine manufacturers, owners and investors. The assessment of the safe operation structure of wind turbines depends on the fatigue and ultimate load evaluation of each main structural component of the wind turbine.

[0003] With the continuous increase of the installed capacity of wind turbines, the terrain and geomorphology of wind farms are becoming more and more complex. The wind parameters (such as wind speed characteristics, wind shear, inflow angle, yaw error, turbulence, pitch rate, wind speed distribution, etc.) at different turbine positions in the same wind farm vary greatly, resulting in different performances of the same type of wind turbines at different turbine positions in the same wind farm. Whether the same type of wind turbines can adapt to the load conditions at different turbine positions in the whole wind farm requires in-depth evaluation. During the preliminary planning and construction period of the wind farm and the bidding stage of wind turbines, wind turbine manufacturers often calculate the ultimate load conditions based on the wind parameters of the whole wind farm and check the safety and reliability of wind turbines based on the results of ultimate conditions. However, obviously, this ultimate load checking mode has certain limitations. It is necessary to quickly and accurately calculate and evaluate the actual load conditions at each turbine position in the wind farm through the existing load simulation calculation results based on a certain wind parameter, and then evaluate the ultimate and fatigue loads of each component of the wind turbine, that is, to evaluate whether the designed load of the wind turbine can adapt to the relevant parameters at the turbine position.
