This paper deals with a numerical investigation on aeroelastic stability characteristics of a 3-MW wind turbine blade. Utilizing a commercial software, a linear aeroelastic model for the blade stability analysis is constructed based on both the blade element momentum (BEM) theory and formulations for flexible multi-body system dynamics. Conventional linear stability analysis, which is suitable for the early stages of blade design, is then carried out by calculating complex eigenvalues of the analysis model taking normal and abnormal operating conditions into account. The results demonstrate that the blade maintains the stability during standard normal operation, and also emphasize the necessity of considering potential abnormal operating events, such as those caused by control system faults, for blade aeroelastic stability analysis.
