  提高风力机将风能转化为机械能的效率,根据我国西北地区的风频风能曲线,用最优设计攻角沿叶片轴线的非线性分布修正传统Wilson算法,优化设计大型水平轴风力机叶片的气动性 能.该优化设计利用Madab优化工具箱,优化速度干涉因子的迭代计算,提高计算效率;考虑多翼型和变攻角等因素对叶片外形优化的影响,从结构及加工工艺角度修正翼型.通过对1.2MW风力发电机组叶片外形的气动性能计算和优化设计,结果表明该优化设计的有效性和可行性,可为风力机叶片外形设计提供参考.(Improve wind turbine wind energy into mechanical energy efficiency, according to the Northwest China wind frequency wind power curve, optimum design angle of attack along the blade axis of traditional non-linear distribution correction Wilson algorithm to optimize the design of the aerodynamic performance of the large-scale horizontal axis wind turbine blades . The Optimal Design Optimization Toolbox Madab optimized for speed interference factor iterative calculation to improve computational efficiency consider multi-airfoil and change the angle of attack and other factors on the blade shape optimization, airfoil from the structure and processing angle correction. By 1.2MW wind turbine blade shape aerodynamic performance calculation and optimization design, the results show that the effectiveness and feasibility of the optimized design can provide a reference for the wind turbine blade shape design.)

  • SVM
     支持向量机方法是建立在统计学习理论的VC 维理论和结构风险最小原理基础上的,根据有限的样本信息在模型的复杂性(即对特定训练样本的学习精度,Accuracy)和学习能力(即无错误地识别任意样本的能力)之间寻求最佳折衷,以期获得最好的推广能力[14](或称泛化能力)。 (SVM is based on statistical learning theory and the theory of VC dimension based on structural risk minimization principle, according to the limited sample of information in the model complexity (ie, training samples of a specific learning accuracy, Accuracy) and learning ability (ie, error-free samples to identify any capacity) to find the best compromise between, in order to obtain the best generalization ability [14] (or generalization).)
