Abstract

The present disclosure provides a method and apparatus for predicting a state of a wind turbine blade, a device and a storage medium, relating to the technical field of wind power generation. The method includes: acquiring an actual ambient parameter and an actual power value of a target wind turbine blade; acquiring an expected power value of the target wind turbine blade based on the actual ambient parameter; acquiring a power droop index based on the actual power value and the expected power value; acquiring an icing risk index of the target wind turbine blade based on a real-time ambient temperature in the actual ambient parameter; and predicting, based on the power droop index and the icing risk index, whether the target wind turbine blade is in an icing state or not. According to this method, whether the wind turbine blade is in the icing state or not is predicted based on the operation data and the ambient parameter of the wind turbine blade, and the accuracy of predicting whether the wind turbine blade is in the icing state or not is improved, and meanwhile, an additional sensor for the prediction of the icing state is not needed, such that application of the method for predicting the icing state is not limited but the method is widely applied.
