Risk prediction method and device for wind generating set

The invention provides a risk prediction method and device for a wind generating set. The risk prediction method comprises the following steps: acquiring full-field topographic information and a plurality of primary selection machine sites of a target wind power plant; risk machine sites are screened from the multiple primary machine sites; performing simulation processing on the wind parameters of the target wind power plant based on the full-field topographic information to obtain wind power plant simulation wind parameters; determining impeller surface simulation wind parameters of the wind generating set at the risk machine site according to the wind power plant simulation wind parameters; and according to the impeller surface simulation wind parameter, a risk identification index of the target risk is determined, and the risk identification index is used for reflecting the possibility that the wind generating set at the risk machine site has the target risk. According to the method and the device, the ri
