The design of wind turbine impeller - hub - Tower System
Abstract
In recent years, the energy crisis and environmental pollution is getting worse,Wind power as a pollution-free, clean and renewable energy has been widespread attention,The world is also increasingly concerned about the importance of wind energy, the corresponding input has been increased,Wind power technology is becoming more and more advanced.
This paper describes the composition structure 1.5MW large horizontal axis wind turbine,Wind turbines is wind energy into electrical energy,Mainly by the wind turbine, nacelle, tower and foundation composition.Thesis on the key components of the rotor, nacelle and tower and other fans to do a detailed analysis,for wind turbines in various states force analysis,By calculating the bending strength of the tower to be checked.
The key part of wind turbines is analyzed by finite element analysis and three-dimensional.
