复杂地形风电场风资源评估精度提升研究

Study on Accuracy Improvement of Wind Resource Assessment in Wind Farms of Complex Terrain

随着风能资源的深入开发,复杂山地成为规模风场热门的微观选址区域。风电场的运行经验表明,地形对空气流动的影响显著,为微观选址带来极大的挑战。空气动力学是风资源评估的理论基础,CFD是其重要的求解与描述手段之一。综述了风电场风资源评估的传统方法,介绍了成熟的CFD方法,并指出提升复杂地形风电场风资源评估精度的方法和路径。

With the deep exploitation of wind energy resource,complex terrains become popular micro-site selection areas for scale wind farms.The operation experience of wind farms shows that the terrain takes obvious effects on wind flow,which poses great challenges for micro-site selection.Aerodynamic dynamics is the theory base of wind energy resource assessment,and CFD is one key solve method.This paper reviewed the traditional methods on wind farm energy resource assessment,introduced the corresponding mature CFD methods and finally pointed out the methods and routines for accuracy improvement of wind resource assessment of wind farms in complex terrains.
