Ice formation on a wind turbine alters the airfoil profiles of the blades and causes degradation in the aerodynamic performance of the wind turbine and the resulting power production losses. Since the blade profile plays a significant role in the icing of a blade, power production losses due to icing can be minimized by optimizing the blade profile against icing. In this study, blade profiles are optimized in order to minimize power production losses. A Gradient based aerodynamic shape optimization method is developed together with the Blade Element Momentum method and an ice accretion prediction tool in order to minimize the power production losses of horizontal axis wind turbines under various icing conditions. In an optimization study performed for the Aeolos-H 30 kW and NREL 5 MW wind turbines exposed to icing conditions up to 1 h, the power loss due to icing is reduced by about 4%.

风力涡轮机上的冰形成会改变叶片的翼型轮廓，并导致风力涡轮机的空气动力性能下降以及由此产生的电力生产损失。由于叶片轮廓在叶片的结冰中起着重要作用，因此通过优化叶片轮廓以防止结冰，可以使由于结冰而导致的电力生产损失最小化。在这项研究中，叶片轮廓经过了优化，以最大程度地减少电力生产损失。结合叶片要素动量法和积冰预测工具，开发了基于梯度的空气动力学形状优化方法，以使各种结冰条件下水平轴风力发电机的发电损失最小。在针对暴露在结冰条件下长达1小时的Aeolos-H 30 kW和NREL 5 MW风力涡轮机进行的优化研究中，
