System and method for controlling temperature of gear box for wind power generator
First Claim
1. A system for controlling a temperature of a gear box for a wind power generator, in which the gear box connects a blade and a generator of the wind power generator, the system comprising:
- a temperature sensor configured to measure a temperature of the gear box;
a temperature adjustment unit configured to adjust the temperature of the gear box in accordance with the temperature of the gear box which is measured by the temperature sensor;
a pitch adjustment unit configured to adjust a pitch angle of the blade; and
a control unit configured to control the pitch adjustment unit so that the blade is rotated at a rotating speed for heating when the measured temperature of the gear box is lower than a range of a normal operating temperature of the gear box,wherein the rotating speed for heating is a rotating speed of blade which is needed to heat the gear box to the range of the normal operating temperature of the gear box within a predetermined time.
