摘要
Abstract
In order to improve the assessment accuracy of wind energy resources for large-scale wind power projects under complex terrain conditions,this paper takes a large-scale wind farm in the eastern of the Yunnan-Guizhou Plateau as the research object,and on the basis of detailed data collection and processing,studies the representativeness of the anemometer tower in this area through Meteodyn WT software,simulates and verifies the represents annual wind speed of the anemometer tower,conducts qualitative research on the representativeness of the altitude and distance of the anemometer towers based on the comprehensive calculation results and wind energy maps,and puts forward corresponding strategies and suggestions for the anemometer tower planning in the early stage of the wind power project.The research results show that:1)The altitude of the anemometer tower and its horizontal distance from the wind turbine positioning point(hereinafter referred to as"anemometer tower distance")have a certain impact on the error size of the calculation results,and as the altitude and distance of anemometer tower increase,the error of the calculation results shows an increasing trend.2)For wind power projects that have not yet set up anemometer towers,it is recommended to place the anemometer towers in areas near the wind turbine locations that are upwind,have relatively open terrain and less terrain obstruction.For areas where wind turbine locations are far away and scattered,anemometer tower locations should be added to increase the representativeness of the anemometer tower and improve the accuracy of wind energy resource assessment in the early stage of the project evaluation.3)For wind power projects that have already established multiple anemometer towers,it is recommended to select a combination of high-altitude and low-altitude anemometer towers for evaluation and calculation,in order to increase the representativeness of the anemometer tower altitude.When the anemometer tower distance is large,it is recommended to select the anemometer tower closer to the wind turbine location point to improve the accuracy of wind energy resource assessment.关键词
