Abstract: In order to improve the economics during the construction and operation of wind farms of complex terrain, it is necessary to conduct research on wind energy resource assessment and micrositing.Taking the Dongzhi wind farm project in Anhui Province as an example, based on the computational fluid dynamics method, a new method using the combination of WT and WindPRO two professional software of wind resource is proposed.Based on the complete annual wind measurement data of the three wind measurement towers in the field, the wind energy resource evaluation, wind energy resource map drawing, power generation calculation and economic comparison are completed, and the wind turbines possessing superior performance and economic efficiency are selected.The results show that:(1)The wind energy resource map calculated by WT is accurate, and the final power generation calculation result is closer to reality than WindPRO′s results;(2)WindPRO has good advantages in wind turbines micrositing and layout scheme, it provides good wind turbine coordinates for WT′s power generation calculation.The research results can provide references for actual engineering design work.
