WIND GENERATOR WITH DEVICE FOR HEATING BLADES Russian patent published in 2023 - IPC F03D80/40 F03D7/04 

FIELD: wind energy.

SUBSTANCE: anti-icing means for wind turbines used in the construction of new wind farms or in existing ones. A wind generator with a device for heating the blades contains a nacelle, a blade, a hub and a tower. Optical-electronic devices are located on the blades, capable of detecting the presence of icing and transmitting a signal to the laser local heating system for its activation. The laser local heating system is located on the ground in front of the wind generator and operates only in the designated heating zone of the wind wheel rotation. Primary position sensors are installed on the leading edge of the blades, and secondary position sensors are installed on the trailing edge of the blades. The laser heating system turns on when approaching the designated heating zone of the primary position sensors and turns off as the secondary position sensors pass from the heating zone.

EFFECT: increase in the efficiency and reliability of wind farms at subzero air temperatures.
