复杂地形测风塔选取方法讨论

Discuss the Methods of Met Mast Siting in Complex Terrain

资源评估的准确与否，对复杂地形风电场的建设和运行有着非常重要的意义，而资源评估的准确性很大程度上依赖于测风塔的选取方法和测风数据的准确程度。因此，本文为讨论复杂地形风电场测风塔的选取方法，以建有8座测风塔的风电场为例，按不同方式选取其中3座测风塔作为输入，利用目前较为主流的CFD风资源计算软件WT和WindSim进行模拟分析。结果表明：复杂地形风电场中，所选测风塔的区域代表性至关重要；同时，测风塔的高度、上风向山体的遮挡情况、是否位于主风向上游等情况也在很大程度上影响评估结果的精度。

The accurate wind resource assessment in complex terrain is very important significance for wind farm construction and operation. The accuracy of wind resource assessment is largely dependent on the method of met mast siting and accuracy wind measurement data. Therefore, this paper discuss the method for the met mast siting, take wind farm with eight masts for example, choose three masts as input in different ways, simulate by WT and WindSim which are widely applied wind resource assessment software in Industry. Results showed that representative of the met masts in the area we choose is very crucial; at the same time, altitude of the met mast, shelter of the upwind mountain and Whether it located at upstream of the main wind direction also greatly affect the accuracy of the assessment results.
