基于CFD与现场测试的叶片气动性能分析研究

The Blade Design Optimization Based on the Fatigue Test

随着风电等可再生能源技术逐渐成熟,可再生能源从补充能源向替代能源转变,陆上上网电价逐级下调,逐步实现"风火同价"的目标。而由于风资源偏差、机组差异等原因导致功率曲线偏离设计值,这对叶片气动性能提出了新的要求。因此如何精确评估叶片气动性能成为了目前各方关注的焦点,通过基于CFD与现场测试的叶片气动性能分析研究,试图找到一种准确评估叶片气动性能的方法,使下一步的性能优化成为可能。

With the developing of the wind power and other renewable energy technology,the renewable energy is gradually changed from complementary energy to alternative energy energy. The land feed-in tariff is cut step by step. It sill be gradually to achieve the goal of same price for the wind power and the thermal power. Due to the wind resource deviation and the difference of the turbine,the power curve deviates from the design. It puts forward new requirements on blade aerodynamic performance. How to evaluate blade aerodynamic performance accurately became the focus of attention at present. The blade aerodynamic analysis based on CFD and field test is performed to try to find a method to assess the blade aerodynamic performance accurately. It will make the performance optimization possible.
