| Abstract: | Taking topography and wind source of one wind area in Xinjiang as study object, this paper analyzes basic data of the historic wind source. By calculating and analyzing main parameters such as wind energy density, wind direction frequen- cy, direction distribution of wind energy density, yearly change of wind speed, turbulence intensity and yearly generating ca- pacity, it optimizes and ensures designed wind speed and power of the wind power generator in favor of this area. By exem- plification, it analyzes impact of wake flow and points out problems to be noted for model selection and configuration fnr th, wind power generator. |
