The power system is destroyed greatly by transmission line icing. We proposed a method of determining icing key influential factor, and defined the definition and analysis step. Moreover, we analyzed the field icing data of 220 kV Tongli line in Guizhou grid by this method, and determined the relation between the micro-meteorological conditions, such as the environmental temperature, humidity, wind speed and conductor temperature, then we compared the results with the grey relation analysis. The results show that the most prominent factor is wind speed, the conductor temperature and the environmental temperature are middle, the least is the environmental humidity.
