狭管地形内部风资源分布特性研究

Research on the Distribution Characteristic of Wind Resources in Narrow Tube Terrain

以位于埃及红海苏伊士湾西岸的某风电场为研究对象,采用理论与实测数据相结合的分析方法对风电场内部的风速、风向进行分析,得到狭管地形内部风资源分布规律。采用不同的风资源评估软件进行测风塔互推,对比实测数据对不同软件模拟此类地形的准确性进行验证。结果表明:狭管地形内部越靠近峡谷中心线的地方,风速越大,越靠近山腰,风速越小;基于CFD的风资源评估软件WT能够模拟出狭管地形的风速分布特性,但仍存在较大误差。

Taking a wind farm located on the west coast of Suez Bay in the Red Sea in Egypt as the research object,the wind speed and wind direction inside the wind farm are analyzed by combining theory and measured data to obtain the distribution law of wind resources in the narrow tube terrain.Different wind resource assessment software is used to simulate the result of a wind tower based on the measured data of another wind tower,and the accuracy of different software to simulate such terrain is verified by comparing the calculation results with measured data.The results show that,the closer to the center line of the canyon,the higher the wind speed,and the closer to the hillside,the lower the wind speed.The CFD-based wind resource assessment software WT can simulate the wind speed distribution characteristics of the narrow tube terrain,but there are still larger errors.
