Title:
METHOD OF OPERATING A WIND TURBINE AND WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2012/025121
Kind Code:
A3
Abstract:
A method of operating a wind turbine has the following steps: receiving (13) multiple sensor signals being indicative of the state of the wind turbine (19); analyzing (14) the multiple sensor signals in order to determine whether a specific alarm condition is met as predefined in one of a plurality of different predefined alarm scenarios (30); further analyzing (15) at least one of the multiple sensor signals in accordance with analyzing steps as predefined in the alarm scenario (30) for which the specific alarm condition is met in order to determine (16) whether the wind turbine (19) is to be put into either a predefined safe mode, a shutdown mode or a continued operation mode.
