Power and Stress Analysis of a Wind Turbine Blade under Various Wind Conditions

Abstract:

Wind Turbine Blade plays a significant role in the efficiency and durability of the wind turbine. As such it is important to identify different ways how the blade performance can be improved. One of the key variables that affects the blade performance is the stress the blade undergoes over time. This paper describes the stress characteristics of a Horizontal Axis Wind Turbine Blade subject to Aerodynamic Forces under normal operating conditions. The stress and deflection that the blade undergoes when subject to rated wind loads are analysed. The simulation results show that most of the stress was experienced at the interface between the spar and the skin of the blade and hence was ignored. The results also show that the skin stress does not exceed 120 GPa and the maximum deflection does not exceed 7m. The power production results agree for wind speeds up to 15 m/s, after which they deviate.
