Analysis on application of vertical axis wind turbines in Qinghai-Tibet Plateau
摘要
Abstract
Most parts of the Qinghai-Tibet Plateau belong to a wind energy resources available area,but variable wind direction characteristic limits the use of horizontal axis wind turbine.Firstly,the distribution and characteristics of wind energy resources in the Qinghai-Tibet Plateau were analyzed.Then,the influence of air density on the output characteristics of vertical axis wind turbines was addressed by using analytical method according to the unique climatic conditions in the plateau.Thirdly,the output characteristics of a vertical axis wind turbine at the air density of 4 000 m altitude was predicted by employing numerical simulation and compared with these under the standard air state.Finally,the influences of special factors such as illumination,radiation,icing and lightning on the turbine were summarized.The results show that the air density has a little influence on the power coefficient,but has a great effect on the output power.At the same wind speed,the output power of the turbine at 4 000 m altitude with the air density of ρ1 =0.843 7 kg/m3 is about 0.60-0.67 times the power in the area of ρ0 =1.225 0 kg/m3.According to the results,the methods for updating wind turbine design and the improvement measures to deal with the environmental factors are put forward.The results in the paper can provide reference for the popularization and application of vertical axis wind turbines under plateau operational conditions.关键词
