高山峡谷地区风能资源利用探讨

使用茂县凤仪镇测风塔2009年6月~2010年5月实时观测资料,对风电场的风能资源各参数进行了详细地计算和分析。茂县一年四季风速较大、风向稳定、定时起风,12~20时达到建设风电场风速,风能资源比较丰富,具有与水电互补性好,占用耕地少,移民少,环境污染小和国家政策扶持等有利条件。茂县的风具有低层偏东逐步转变为高层偏西风,风速由下到上逐步减小的特点,架设风力发电的涡轮高度相对较低,不利于大型风电场建设,但适宜建设中小型风电场,具有一定的开发利用价值。 

Discussion about the Utilization of Wind Energy Resources in High Mountains and Canyons

With the real-time observation data recorded by wind tower in Fengyi, Maoxian County during June 2009 to May 2010, the parameters of wind energy resources in wind farm were calculated and analyzed in detail.In Maoxian County, the wind speed is great throughout the year, the wind direction is stable, the wind starts at regular time, and the wind speed during 12:00 to 20:00 reaches the requirements for construction of wind farm.There are lots of advantages for building wind farm here, as the wind energy resources are rich, which is good complementary to the hydropower, and may conduce less farmland impropriation, less immigration, and less environmental pollution, also has the national policy supports here.The wind in Maoxian County, with the characteristics of gradually changed from the easterly wind in the lower layer to westerly wind in the higher layer, and the wind speed decreases from the bottom up, may course the turbine height for erection of wind power to be relatively low, where only the small or medium sized wind farm, other than large-scale wind farm, is suitable for constructing, and has certain value for development and utilization.
