摘要： A wind turbine includes a generator for converting wind energy into electrical energy, a hydrogen production system for producing hydrogen by means of the electrical energy, a first auxiliary group of electrical consumers, a second auxiliary group of electrical consumers, and an auxiliary power network for powering the first auxiliary group and the second auxiliary group, wherein only the first auxiliary group is electrically disconnected from the auxiliary power network by means of one or a plurality of switch disconnectors to reduce the energy consumption of the auxiliary power network. Due to the one or the plurality of switch disconnectors, it is possible to disconnect the first auxiliary group from power. This helps to save energy in the case that the first auxiliary group is not needed for the operation of the wind turbine.

摘要： A method for transitioning a wind turbine into an energy harvesting mode in which the wind turbine generates electrical power from wind energy is provided. An energy storage system supplies electrical power to an auxiliary system when the wind turbine is not generating or receiving electrical power sufficient for supplying the auxiliary system. The method includes operating the wind turbine in a first operating mode in which an electrical power supply is ceased; obtaining environmental data including at least one of wind data and meteorological data; and determining if the obtained environmental data meets a predefined condition. If the predefined condition is met, a transition of the operation of the wind turbine into the energy harvesting mode is caused, wherein transitioning the operation into the energy harvesting mode comprises supplying electrical power from the energy storage system to the one or more auxiliary power consumers of the first group.
