Abstract: A method for controlling noise generated by a wind farm with a plurality of wind turbines is disclosed. In the event that a predicted noise level exceeds a predefined threshold noise value, one or more wind turbines are selected using a noise propagation model and respective wind turbine models for the selected one or more wind turbines, and by performing an optimisation process to reduce the predicted noise level at the predefined evaluation position to a level below the predefined threshold noise value while maximising the total power production of the wind farm.

Abstract: A method for validating a version of wind turbine control software is disclosed. A first version of the wind turbine control software and a second version of the wind turbine control software are running simultaneously on a controller, by applying identical control input to the first version and to the second version, and the first and the second versions of the wind turbine control software each generating control output, based on the received control input. The wind turbine or wind farm is controlled based on the control output generated by the first version of the wind turbine control software. The control output generated by the first version and by the second version of the wind turbine control software are compared, during a time interval, and the second version of the wind turbine control software is validated, based on the comparison.

The turner gear assembly (52) includes a turner gear (50) configured to couple to the drivetrain (30) and having at least two motors (58a, 58b), and a valve block (78) connectable to the turner gear (50) and having a first flow control valve (106) configured to be in fluid communication with a pump (80) and with the at least two motors (58a, 58b). The first flow control valve (106) is selectively moveable between a first fluid control position (106a) and a second fluid control position (106b). When the first flow control valve (106) is in the first fluid control position (106a), the at least two motors (58a, 58b) operate in parallel and when the first flow control valve (106) is in the second fluid control position (106b), the at least two motors (58a, 58b) operate in series. A method of operating the turner gear assembly is also disclosed.

Abstract: The invention provides a method for controlling a wind power plant that receive operating command requests via a distributed system comprising a plurality of subsystems each associated with a respective party capable of issuing requests. One subsystem generates a request to operate the wind power plant in accordance with a defined operating command desired by the associated party. The request is broadcast to each of the other subsystems to approve or disapprove the requests. Each subsystem broadcasts to the other subsystems if it approves the request, and each subsystem maintains a database including a record of which subsystems have approved the request. The wind power plant is controlled based on which subsystems have approved the request, where at least one subsystem other than the subsystem that generates the request needs to have approved the request before the plant implements the defined operating command.

Abstract: An aspect of the invention relates to a method of reinforcing a tubular wind turbine structure using a radially adjustable ring stiffener. The ring stiffener comprises a pair of adjacent ring segments coupled together by a coupling means configured to permit radial adjustment of the ring stiffener by varying an intersegmental separation between adjacent ends of those ring segments. The method comprises: positioning the ring stiffener at a reinforcement position within the tubular wind turbine structure; and adjusting the intersegmental separation between the pair of adjacent ring segments to increase the radius of the ring stiffener; and thereby to engage an inner surface of the tubular wind turbine structure with a radial force that holds the ring stiffener at the reinforcement position by means of friction between the ring stiffener and the tubular wind turbine structure.
