Changing a mode of operation of a wind turbine

摘要

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.

1. A method of operating a wind turbine, comprising:
receiving multiple sensor signals being indicative of a state of the wind turbine; analyzing at least a first one of the multiple sensor signals in order to determine whether a specific alarm condition is met, wherein the alarm condition is defined in one of a plurality of different predefined alarm scenarios; and upon determining that the alarm condition is met, fault checking the first sensor signal using at least a second one of the multiple sensor signals and a fault checking technique defined in the alarm scenario corresponding to the alarm condition to determine whether the wind turbine is to be put into one of: a predefined safe mode, a shutdown mode, and a continued operation mode.
