Abstract
A method of controlling a wind turbine is provided, including the steps of detecting a power-on time (TAP_on) at which auxiliary power becomes available after an absence of auxiliary power; determining, at power-on time (TAP_on), the elapsed time (Telapsed) since a dryness requirement of the wind turbine was satisfied; and subsequently initiating a wind turbine start-up procedure if the elapsed time (Telapsed) does not exceed a predetermined duration (Tsafe) or inhibiting a wind turbine start-up procedure if the elapsed time (Telapsed) exceeds the predetermined duration (Tsafe).
Claims10
A method of controlling a wind turbine, the method comprising:
- detecting a power-on time at which an auxiliary power for the wind turbine becomes available after an absence of the auxiliary power;
- determining, at the power-on time, an elapsed time since a dryness requirement of the wind turbine was satisfied, the dryness requirement including at least a dryness of an electrical system of the wind turbine;
- and either
- initiating a wind turbine start-up procedure if the elapsed time does not exceed a predetermined duration, or
- inhibiting the wind turbine start-up procedure if the elapsed time exceeds the predetermined duration.
