METHOD OF PROTECTION AGAINST ICE COVERING, USING CARBON FIBRE AND ANTI-ICE SYSTEM FOR WIND GENERATORS, BASED ON APPLICATION OF THIS METHOD Russian patent published in 2017 - IPC F03D7/00 F03D80/40 

FIELD: electricity.

SUBSTANCE: method of protection against the ice covering, using the carbon fiber, which includes the following steps: installation on the surface layer or at the nearest to the surface layer of the carbon electroheating plates blade, forming the heating layer. The different power is set for the carbon electroheating plates in accordance with the linear velocity change in different radial positions of the wind turbine blade during the operation; the release of at least one heating area in the heating layer at different sections of the blade. The carbon electro-heating plate of each heating area is connected to the current output of the corresponding thermostat by the parallel, series or series-parallel connection; the temperature sensors installation near the carbon electro-heating plate and on the heating areas surfaces; casting of carbon electro-heating plates, temperature sensors and other structural layers in one piece with the blade, using the vacuum impregnation technology. The temperature sensor of each heating area is connected to the signal input of the corresponding temperature controller, the temperature and humidity sensor of the ambient air and wind speed is connected to the signal input of the thermostat. To maintain the temperature of the heating areas outer surface, exceeding 0°C, the thermostat controls the operation of the carbon electro-heating plates of the individual heating areas in accordance with the signals of the temperature and humidity sensor of the ambient air and wind speed and the signals from the heating areas temperature sensors.

EFFECT: stability and uniformity of heating and energy saving.
