WIND TURBINE AND METHOD FOR HEATING A COMPONENT IN A WIND TURBINE
First Claim
1. A wind turbine comprising:
- a nacelle;
at least one component mounted in said nacelle;
a first temperature sensor for detecting a temperature of said component;
a second temperature sensor for detecting a temperature outside of said nacelle;
a heater associated with said component in order to heat said component;
a heater controller operatively connected to said heater;
said first and second temperature sensors being connected to said heater controller for applying first and second input quantities thereto so as to activate said heater when the detected temperature of said component lies below a predetermined switch-on value for said heater;
said switch-on value for said heater depends in at least one predetermined temperature interval on the outside temperature detected by said second temperature sensor; and
,within said at least one predetermined temperature interval, said switch-on value at a first value of said outside temperature is greater than said switch-on value at a second value of said outside temperature when said second value of said outside temperature is greater than said first value of said outside temperature.

Abstract
A wind turbine has a nacelle wherein a component is equipped with a first temperature sensor for detecting a temperature of the component, a second temperature sensor for detecting an outside temperature inside or outside the nacelle, a heater associated with a component to heat the latter, and a heater controller. The detected temperature of the component and the detected outside temperature are provided as input signals to the heater controller which activates the heater for heating when the detected temperature of the component is below a predetermined switch-on value for the heater. The switch-on value for the heater is, in at least one predetermined temperature interval, depending on the detected outside temperature. The switch-on value for a first outside temperature is greater than the switch-on value for a second outside temperature in the temperature interval when the second outside temperature is greater than the first outside temperature.

15. A method for heating a component in a wind turbine, the method comprising the steps of:
-
detecting a temperature of the component of the wind turbine; detecting an outside temperature; determining a switch-on value for a heater of said component depending on the detected outside temperature wherein the switch-on value for a first outside temperature is greater than the switch-on value for a second outside temperature when the second outside temperature is greater than the first outside temperature; and
,switching on the heater when the detected temperature of the component is below a switch-on value. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
