The invention belongs to the field of wind
turbine blade ice prevention and removal, and particularly relates to an optimized wind
turbine blade deicing method. The optimized wind
turbine blade deicing method comprises the following steps that a wind
turbine blade is divided into a high / low-power continuous heating area and a periodic heating area; the required current heat is calculated by setting the initial value of the surface temperature of the blade; the current heat rate is adopted for testing, the current heat rate value is adjusted, and the optimal electric
heat flow rate needed by the low / high-power continuous heating area is obtained; the accumulated ice shape of the periodic heating area is obtained through tests of the two optimal values, the
icing resultant force is obtained through
simulation calculation according to the accumulated ice shape, the
icing adhesion force is made to be equal to the
icing resultant force, the surface temperature of the periodic heating area is obtained through calculation, and then the
electric heating flow rate needed by the periodic heating area is obtained; and finally, the optimal
heat flow rate values, obtained through tests and
simulation, of all the areas are used for controlling all the areas for deicing. According to the optimized wind
turbine blade deicing method,
energy consumption can be reduced on the basis of effective deicing, and
economic benefits of a
wind power plant can be improved.
