Abstract: A wind turbine generator controller is described. The controller comprises switching circuitry, for selectively activating and deactivating one or more transducer circuits, and overcurrent detection circuitry, for detecting an overcurrent state in relation to one or more of the transducer circuits. The switching circuitry is responsive to the detection on an overcurrent state to selectively deactivate one or more of the transducer circuits.

Abstract: Disclosed is a method, performed by a root cause analysis system. The method comprises obtaining operational data associated with operation of a wind turbine system in response to a fault of the wind turbine system. The method comprises determining, based on the operational data, a set of candidate root causes associated with the fault, by applying a machine learning model to the operational data. The machine learning model is configured to classify and/or locate one or more candidate root causes. The method comprises providing, based on the set of candidate root causes, output data indicative of at least one root cause of the fault of the wind turbine system.

Abstract: The present invention relates to verification of connections between a computing unit, such as a test computer, and a device, e.g. a sensor or transducer, in a fieldbus network of a sub-assembly of a wind turbine. The fieldbus network comprises a plurality of network components. One of the network components comprises a program element. The computing unit is arranged for forwarding a request to the program element to verify the connection from the computing unit to a selected device, the request comprising a sequence of selected network components between the computing unit and the selected device. The program element is arranged to establish in a sequenced manner a communication connection between the selected network components and the selected device, and to provide a response as to whether or not the connection exists.
