摘　　要：为了应对全球气候变暖问题,风电作为清洁高效的可再生能源,受到世界各国的高度重视并得到大力发展。但目前风电机组能效偏低问题已成为风电场特别是老旧机组运行过程中普遍存在的问题,严重影响风电场发电经济效益。因此该文章从偏航控制、变桨控制等方面分析研究风电机组能效,查找存在的问题,并提出优化建议。In order to deal with the problem of global warming, wind power, as a clean and efficient renewable energy,has been highly valued and developed by countries all over the world. However, at present, the problem of low energy efficiency of wind turbines has become a common problem in the operation of wind farms, especially old units, which seriously affects the economic benefits of wind farms. Therefore, this paper analyzes and studies the energy efficiency of wind turbine from the aspects of yaw control and pitch control, finds out the existing problems, and puts forward some optimization suggestions.
