FIELD: power industry.
SUBSTANCE: wind power plant has at least one rotor blade (108), a heating system (400) for at least one portion of at least one rotor blade (108), at least one temperature sensor (510) for detecting an outside temperature in the zone or in (100), at least one humidity sensor (520) for detecting the air humidity in the zone or in the environment of the wind power plant (100) and the control unit (300) for activating the blade heating system (400), if the temperature drops below the limit value and if the limit value of air humidity is exceeded. The temperature limit is +5°C and the limit value of air humidity is 70%, the temperature limit is +2°C or the limit value of air humidity is 95%.
EFFECT: preventive activation of the blade heating system.
