复杂地形风资源分布计算的研究

摘要

Wind resources calculation and distribution are the basis work of the wind farm development, which are directly related to the accuracy of the micro site and influence economic benefit of wind farm. This paper studies the theory for the wind resource distribution such as the change rule of the wind shear coeffi-cient and ground roughness, change of weibull distribution parameters by height variation and wind resource calculation model. Furthermore, by taking the wind farm as a case to calculate, it verifies the correctness and practicability of the theory, providing theoretical basis and guidance of engineering applications for the study of resources distribution in complex terrain.%　　风资源计算及分布是风电场开发的基础工作，直接关系着微观选址的准确性，影响风电场经济效益。研究了风切变系数与地面粗糙度变化规律、威布尔分布参数随高度变化规律、风资源计算模型等风资源分布的理论，并以某风电场为例进行计算，验证了理论的正确性及实用性，为复杂地形风资源计算及分布研究提供了理论基础及工程应用指导。
