Mountain wind power plant fan blade icing prediction method and program product

The invention discloses a mountain wind power plant fan blade icing prediction method and a program product, and the method is provided with a plurality of fan blade icing prediction models corresponding to a plurality of mountain wind power plant micro-terrain areas one by one. Selecting a fan blade icing prediction model corresponding to the current mountain wind power plant microtopography area as a current fan blade icing prediction model; based on the meteorological element observation value of the current mountain wind power plant micro-topography area, a meteorological element prediction result of the current mountain wind power plant micro-topography area is obtained through a meso-and-small-scale mode coupling multiple nested numerical prediction algorithm; and inputting the meteorological element prediction result into the current fan blade icing prediction model, and obtaining the predicted fan blade icing thickness based on a formula d = f (g (A), m (B)). According to the invention, the icing cond
