Problems solved by technology
After the blade freezes, the shape of the blade will change to a certain extent, which will affect the aerodynamic performance of the blade and reduce the power generation; icing will also increase the unbalanced vibration and overall load of the blade, reduce the power output of the fan, and even affect the power output of the fan. Safe operation causes great harm; therefore, rapid deicing of blades after freezing is not only a demand for economic benefits, but also a necessary requirement for safe operation

The invention discloses a film-structure heating deicing system for the outer surface of a wind turbine blade. The film-structure heating deicing system for the outer surface of the wind turbine bladecomprises a control system, a film heating system and an electricity conducting system. The control system is connected with the film heating system through the electricity conducting system. The film heating system is connected to the outer surface of the blade. The film-structure heating deicing system for the outer surface of the wind turbine blade has the beneficial effects that the film heating structure adopts one or more film structure forms, face heating is conducted, so that the heating efficiency is high, heating is uniform, and the damage to the wind turbine blade is small; the heating area is partitioned, each area can achieve independent heating, accurate deicing is achieved, and energy consumption is reduced; and when anti-icing work is needed, the film-structure heating deicing system can operate at a low power, and therefore energy is saved.
Description
technical field [0001] The invention relates to a blade of a wind power generating set, in particular to a heating and deicing system with a film structure on the outer surface of the wind power blade. Background technique [0002] Wind power generation has been widely used. Under low temperature conditions, if it encounters humid air, rain, snow, frost and other climates, its blades will freeze. After the blade freezes, the shape of the blade will change to a certain extent, which will affect the aerodynamic performance of the blade and reduce the power generation; icing will also increase the unbalanced vibration and overall load of the blade, reduce the power output of the fan, and even affect the power output of the fan. Safe operation causes great harm; therefore, rapid deicing of blades after freezing is not only a demand for economic benefits, but also a necessary requirement for safe operation. Contents of the invention [0003] The invention provides a heating sy...
