Abstract (en)
[origin: WO2018091497A1] The invention relates to a wind turbine (2) and to a method for operating same. The wind turbine (2) comprises a rotor (4) and a brake device (20). The brake device (20) comprises a mechanical brake mechanism (22) which is mechanically coupled to the rotor. The brake device (20) comprises at least an electric and/or hydraulic switching element (24) for activating and/or deactivating the brake mechanism (22), and the switching element (24) is redundant and/or is designed to be fail-safe. Furthermore, a controller (26) is provided which is designed to receive an interference signal (S) and activate the switching element (24) in response to the received interference signal (S), thereby activating the brake mechanism (22). The brake mechanism (22) is deactivated by means of the switching element (24) before the rotor (4) of the wind turbine comes to a standstill.
