Abstract

A novel approach，which utilizes a modified blade element-momentum theory and the finite element method，is presented to analyze the blade performance of wind turbine considering aeroelasticity． Then，the ap-proach is used to analyze the performance of the blades of an 850MW wind turbine at various wind speeds． The re-sults show that aeroelasticity obviously influences the performance of large-size wind turbines at high wind speed and greatly reduces the accuracy of the original design． The presented approach is of guiding significance for the aerody-namic shape design，load calculation and structural design of blades．

Key words： wind turbine; blade performance; aeroelasticity; blade element-momentum theory; finite element a-nalysis
