This invention discloses a design method for an anti-icing and de-icing system based on the icing characteristics of wind turbine blades, belonging to the field of wind power generation technology. Based on the regularity of icing occurrence and growth in the chordal and spanwise directions of the blades, and the potential failure of anti-icing coatings in severely icing areas under severe freezing weather conditions, combined with blade icing tests and a database of spatiotemporal icing development characteristics, this invention proposes a highly efficient anti-icing and de-icing system design and a highly efficient, low-energy-consumption operation control method that combines an active electrothermal film de-icing method with a passive anti-icing coating method. This enables wind turbines to operate continuously without blade icing in all climates. This invention fully integrates the advantages of electrothermal de-icing technology and anti-icing coating technology, enabling wind turbine blades to have highly efficient anti-icing and de-icing functions under all climate conditions, and features low system energy consumption.
