风电机组叶片涡流发生器应用效果评估

Assessments of Vortex Generators on Wind Turbine blade

目前加装涡流发生器已成为一种提高风力机功率的有效方法，但其对功率提升效果评估方法并不统一：本文采用标准功率曲线验证的方法，对某风场机组进行了加装涡流发生器前后的现场实测，并对其安装前后的功率曲线和年发电量AEP进行了计算分析。结果表明，被测风机在加装涡流发生器后，计算年发电量提升在0．5％～1．0％之间；采用机舱风速评估提升效果会存在较大误差。

Installation of Vortex Generators （VGs） has already been one of the efficient methods to improve the performance of wind turbine.However, the methodology to evaluate the improvement of VGs is not uniform.The paper measured the power curves and estimated Annual Energy Productions （AEP） of one wind turbine in the wind farm used the standard power curve method based on IEC 61400-12-1.The results show that the AEP of the test wind turbine has improved 0.5%-1.0%, and the en＇ors have been existed when using the wind velocity on nacelle.
