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 steps of obtaining topographic information of a wind power plant where a wind generating set is located; based on the topographic information, performing simulation processing on the wind parameters of the wind power plant to obtain wind power plant simulation wind parameters; determining impeller surface simulation wind parameters of the wind generating set according to the wind power plant simulation wind parameters; according to the impeller surface simulation wind parameters, risk identification indexes of the target risk of the wind generating set are determined, and the risk identification indexes are used for reflecting the possibility that the wind generating set has the target risk. According to the method, the refined simulation wind parameter of the impeller surface at the machine position point is determined, and then the risk identification index of the target risk is det
