Abstract
By considering the effects of wind shear, tower shade and three-dimensional rotation, an improvement of the classical blade element momentum (BEM) theory was presented and a model for wind turbine aerodynamic performance was further established. Based on this model, a numerical algorithm and a program code were developed. Using a commercial 1.5 MW wind turbine as an example, the tangential and transverse aerodynamic load distributions, thrust and generator power, aerodynamic power coefficient were numerically analyzed for various conditions of wind speed, rotor speed and pitch angle. The numerical model and results were verified by comparing with the results of FOCUS5, a well-known software for wind energy design and analysis. © 2011 Chinese Society for Electrical Engineering.
