Problems solved by technology
In addition, even in the same wind farm, the icing start time and ice thickness of wind turbines in different locations are not completely the same, and it is difficult to carry out icing prediction at the level of wind turbines in wind farms
[0003] Existing icing monitoring and early warning systems based on SCADA systems or other monitoring methods only perform extrapolation calculations of fan blade icing based on live data, and the warning time is only a few hours, which cannot achieve accurate prediction of day-ahead power considering fan blade icing shutdown , cannot scientifically guide the dispatching department to adjust the operation mode in advance

The embodiment of the invention provides an icing thickness prediction method and device based on wind power plant monitoring data, a processor and a storage medium. The method comprises the following steps: determining a mapping relation of meteorological elements between the anemometer tower and each fan according to historical observation data of the anemometer tower and the fans; determining the icing state of each fan at a preset time point according to the mapping relation; determining the change value of the icing thickness of each fan according to the icing state of each fan; for each fan, determining an icing thickness value of the fan at the preset time point according to the change value and the icing thickness at the previous time point; and determining an icing thickness prediction value of the fan at a future preset time point according to an icing increment prediction value within the future preset time point of the preset time point. And based on the prediction calculation result of the icing thickness, when the icing thickness of the fan exceeds a preset value, performing prediction and early warning for the operation condition of the fan.
Description
technical field [0001] The present application relates to the technical field of wind power generation prediction, and in particular to a method, device, storage medium and processor for predicting ice thickness based on wind farm monitoring data. Background technique [0002] With global climate change, cold waves and freezing disasters occur frequently in winter, and wind turbines are often located in mountainous areas with strong winds, bringing more cold and wet water vapor, which makes the ice coating of wind turbine blades more serious than other areas. In addition, even in the same wind farm, the icing start time and icing thickness of wind turbines at different locations are not exactly the same, making it difficult to predict icing at the wind turbine level in wind farms. [0003] Existing icing monitoring and early warning systems based on SCADA systems or other monitoring methods only perform extrapolation calculation of fan blade icing based on actual data, and t...
