陕西省金润河北镇风电场风能资源开发评估

Evaluation of Wind Energy Resources Development in Wind Power Plant in Jinrunhe North Town of Shaanxi Province

对陕西省宝鸡市陇县金润河北镇风电场气象条件、风功率密度、平均风速、主导风向等风能参数进行分析评价。结果表明,测风塔100 m高度月平均风速、月平均风功率密度最大均出现在4月,最小均出现在8月;测风塔100 m高度主导风向为SSW(南西南),主要风能方向为SSW(南西南),风电场风功率密度等级为1级。风电场安装20台2500 kW的风电机组,装机容量50 MW,年设计发电量1.33485×108 kW·h,年出厂电量9.5426×107 kW·h。结果可为其他风电场选址和发电量估算提供参考。

This paper analyzed and evaluated wind energy measurements such as meteorological conditions,wind power density,average wind speed,and dominant wind direction of the wind power plant in Jinrunhe North Town,Long County,Baoji City,Shaanxi Province.The results showed that the maximum monthly average wind speed and the monthly average wind power density at the height of 100 m of the wind measurement tower all appeared in April and the smallest in August.The dominant wind direction at 100 m height of the wind measurement tower was south-southwest,the main wind energy direction was south-southwest,and the wind power density level of this wind farm was level 1.The wind power plant was equipped with 202500 kW wind turbines with an installed capacity of 50 MW.The annual design generated energy of which was 134.8485 million kW·h,and the annual power output was 95.426 million kW·h.The results could provide reference for site selection and generated energy estimation of other wind power plants.
