Blade deicing system and method

The invention belongs to the technical field of wind power generation, and discloses a blade deicing system and method, and the method comprises the steps: obtaining blade state data collected by an icing detection device in real time and corresponding collection time data through a data collection module; performing integration processing on the blade state data and the corresponding acquisition time data to obtain a time sequence data set; inputting the time sequence data set into an icing state detection model in a blade icing detection module for classified prediction to obtain icing state data corresponding to the time sequence data set; wherein the icing state detection model is constructed based on a recurrent neural network; and judging the icing state data, and when the judgment result is that the blade is iced, controlling the deicing device to deice the blade through a deicing control module. According to the technical scheme, the icing state of the blade can be accurately judged, and targeted deic
