Abstract

In order to study the effect of the floating platform motion on the aerodynamic performance of offshore wind turbine, this paper analyzes the aerodynamic performance under different amplitudes of tossing movements on unsteady Blade Element Momentum Theory (BEM).The numerical model for aerodynamic performance of floating wind turbine under control system is established, which is based on the model of 5MW offshore wind turbine of National Renewable Energy Laboratory (NREL). Due to the limitation of the unsteady Blade Element Momentum Theory itself, the dynamic wake model and the yawing correction are added into the unsteady BEM theory with the Prandtl blade tip and hub loss correction, the Glauert correction and three-dimensional rotation correction. The change of thrust, torque and power in six degrees of freedom are received by calculation and the laws about aerodynamic performance of the offshore wind turbine under the six degrees of freedom platform motion is summarized.
