The Shape Optimization of Wind Turbine Blades Based on Multidisciplinary Design Optimization
摘要
Abstract
Based on the aerodynamics of wind turbine,structural dynamics of blades and output power performance,the relationship between them was discussed.The multidisciplinary design optimization model of the blades was presented whereas the objective was cost of energy which is calculated from the Annual Energy Production（AEP） and the cost of the whole rotor.Using this model,a 5 MW rotor was optimized and the design variables were the chord,twist angle and relative thickness of blades.The cost of the optimized rotor was reduced by 2.6% comparing with the original rotor.To valide the optimization results,the comparison of the load between the optimized and original blade were calculated and plotted.关键词
