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).
Claims15
A method of controlling a wind turbine, comprising:
- detecting a power-on time at which an auxiliary power becomes available after an absence of the auxiliary power;
- determining, at the power-on time, the elapsed time s-since a dryness requirement of the wind turbine was satisfied;
- and
- initiating a wind turbine start-up procedure if the elapsed time does not exceed a predetermined duration,
- or
- inhibiting a wind turbine start-up procedure if the elapsed time exceeds the predetermined duration.
A wind turbine comprising:
- a plurality of electrical systems arranged in an interior of the wind turbine;
- a means for detecting a power-on time at which an auxiliary power becomes available after an absence of the auxiliary power;
- a means of determining, at the power-on time, an elapsed time since a dryness requirement of the wind turbine was satisfied;
- and
- a means of initiating a wind turbine start-up procedure if the elapsed time does not exceed a predetermined duration,
- or
- inhibiting a wind turbine start-up procedure if the elapsed time exceeds the predetermined duration.
