Abstract

To enhance the utilization rate of wind energy, introduce a new kind of Movable Wind-drive Device and research the influence of crosswind on aerodynamic performance of wind turbine in wind-drive device. Based on blade coordinate system and feline coordinate system, carry on a vector decomposition of wind velocity and obtain the change rules of every velocity component. According to the classical momentum-blade theory and strip analysis theory, analyze the aerodynamic model in positive direction wind and in negative direction wind, research the difference of the formulas in two cases, get the impact of the crosswind on wind turbine blades. Calculation results express that axial thrust and torque possess periodic local impact on the middle section of wind turbine.
