EVALUATING THE WIND RESOURCES IN AN AREA THAT IS EQUIVALENT TO THE SIZE OF A WIND POWER PLANT: A METHODOLOGY

Abstract

Surveying the wind resources in a specific area is one of the first and important stages to be able to proceed with the construction of a wind power plant in order to proceed with building a wind power plant. In fact, the current meteorological forecasting software usually only conducts calculations on a large scale and the given results are also representative, the average value for the entire area. In this paper, we will present a method of assessing wind resources in a small area, equivalent to the size of a wind power plant. The selected area to build the model is the hilly part of Ninh Phuoc district, Ninh Thuan province. The Computational Fluid Dynamics (CFD) method in Ansys CFX software and Blender GIS data will be used to accurately model the topography of the area and conduct wind flow analyzes in this area. The results obtained are the values of the wind velocity with respect to the height in the entire three-dimensional space of the model, especially at characteristic locations such as valleys, mountain slopes and peaks. Based on the obtained results, we can accurately determine the distribution of wind speed at each specific location and from there can determine the best locations to install wind turbine towers.
