基于风资源评估的风电机组设计风速分析

Analysis on Designed Wind Speed of Wind Power Generator Based on Wind Source Estimation

以新疆某风区的地形、风资源情况为研究对象,分析其历史风资源基础数据。通过计算、分析风能密度、风向频率及风能密度的方向分布、风速年变化、湍流强度、年发电量等主要参数,优化和确定有利于该地区的风力机设计风速和功率。通过例证分析了尾流的影响,指出进行风力发电机组选型和配置时应注意的问题。

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.
