摘要
以1.5 MW风电机组叶片为模型,通过叶片数据采集和实验分析的方法,对外部环境对风电机组性能影响进行分析。通过Bladed软件对风电机组叶片进行仿真,研究结果表明:温度和高度的变化对空气密度和空气黏度的变化有一定影响,空气密度的变化引起升阻比变化,空气黏度的变化则主要引起雷诺数的变化,两者共同对风电机组的气动性产生影响。该研究有助于风电机组的设计研发,降低风电机组运行时的故障率。
Taking the 1.5 MW wind turbines blade as a model,the influence of the external environment on the performance of the wind turbines is analyzed by the method of blade data acquisition and experimental analysis. The blade of the wind turbines is simulated by bladed software. The results show that the change of temperature and height has a certain influence on the change of atmospheric density and atmospheric viscosity. The change of lift drag ratio is caused the change of air density and the change of Renault number mainly is caused atmospheric viscosity. Therefore,the change of temperature and height has a common effect on the aerodynamics of wind turbines. The research is helpful to the design and development of wind turbines and to reduce the failure rate of wind turbines during operation.
