In winter, icing is one of the key factors that restrict the generation of wind power in high-altitude mountains. In this paper, through analyzing the upper air temperature profile of wind farms by using microwave radiometer, we established the water drop temperature calculation formula under non-phase change conditions. Three vertical temperature structures conditions and the relationship between ground water drop temperature and icing efficiency under different conditions are analyzed. This study makes up for the deficiency that the wind turbine icing numerical prediction model can only give the three-dimensional ambient temperature, but cannot give the icing efficiency, which will improve the prediction accuracy of wind turbine icing.
Key words: Frozen wind turbine / Microwave radiometer detect / Upper air temperature / Icing efficiency
