Abstract In this paper, the dynamic effects of wind turbine installation angle and wind turbine pendulum motion on the constant wind vector and the variation of the real wind vector acting on the blade are discussed respectively. The effects of these two conditions on the aerodynamic load and torque of wind turbine are analyzed. Based on this theory, the classical BEM is dynamically modified and the specific method of dynamic correction is proposed. The modified BEM is used to simulate the aerodynamic load and blade load distribution of wind turbines. By comparing and analyzing the previous methods, the correctness of this method is proved. A new aerodynamic load calculation method is proposed for the new energy industry, especially for the wind energy industry, which can assist engineers in the design, analysis, control and evaluation of wind turbines.
