Abstract: A method of providing safety configuration parameters for a wind turbine is provided. The method comprises receiving a safety configuration file at a location of the wind turbine, and comparing a turbine ID associated with the safety configuration file to a turbine ID of the wind turbine stored at the location of the wind turbine. A tamper check is performed on the safety configuration file to determine if data in the safety configuration file has been modified. If the turbine ID associated with the safety configuration file matches the turbine ID of the wind turbine, and if the tamper check determines that the data has not been modified, a safety configuration parameter associated with a safety system of the wind turbine is extracted from the file and stored.

Abstract: The invention relates to a method for configuring a wind turbine. The wind turbine comprises at least one controller arranged to control a function of the wind turbine, and a data storage unit arranged to store controller specific data for the at least one controller, where the data storage unit is associated with the at least one controller to enable communication of the controller specific data between the data storage unit and the at least one controller. The method comprises detecting a connection between a programming enabling key and a connection interface dependent on a presence of the programming enabling key in proximity of the connection interface, initiating a programming mode wherein a control unit is enabled to receive controller specific data or wind turbine specific data from which the controller specific data can be determined, and obtaining the controller specific data or the wind turbine specific data via a manual action or via a trusted data source.

Abstract: Embodiments herein describe validating an emergency stop signal before activating a brake within a wind turbine. The emergency stop signal is received from a control node of a plurality of control nodes distributed throughout the wind turbine, and the emergency stop signal indicates that the wind turbine should be shut down. The wind turbine is shut down by transmitting a shutdown signal to the plurality of control nodes. Upon determining there is no indication a person is present within the wind turbine, the emergency stop signal is validated. Additionally, upon determining the emergency stop signal is valid, a brake within the wind turbine is activated to bring the rotor to a stop.

Abstract: To safely operate a wind turbine, a control system may determine a current state of the wind turbine and identify whether the state is within an operational envelope. Based on measured sensor data, the control system may calculate the current state of the turbine in a multi-dimensional space where each axis of the multi-dimensional space correlates to one of the measured parameters. The boundary of the operational envelope may define a region of the multi-dimensional space where the wind turbine is behaving in a safe manner. A safety system may determine if the state determined by the control system is accurate. If so, the safety system determines whether the current state is within the operational envelope. If the state is outside the envelope, the wind turbine may switch to a safe state during which the turbine may be decoupled from the utility grid or the rotor is stopped.

Abstract: Systems, methods, and computer program products for monitoring occurring rotor imbalances. A dynamic characteristic sensor (40) determines the value of a dynamic characteristic of a wind turbine (10), e.g., of a nacelle (14) thereof, such that the dynamic characteristic includes a component aligned with a rotor plane (50) of the rotor (16). The dynamic characteristic is sampled when the rotor (16) of the wind turbine (10) is at each of a plurality of azimuth angles (ψn) to produce a sequence of dynamic values (a(ψ)). An azimuth-domain transform is applied to the sequence of dynamic values (a(ψ)) to generate at least one inverse-angle component (A(γk)). Rotor imbalances are then detected based on the inverse-angle component (A(γk)), such as by comparing a value of the inverse-angle component (A(γk)) to a threshold, and the rotation of the rotor is stopped.

Abstract: The present invention relates tocontrol of wind turbines based on predicted operational trajectories. A control system for a wind turbineis described wherea main controller calculating one or more predicted operational trajectories and a safety controller validates at least one of the one or more predicted operational trajectories. The control system controls the wind turbine with the predicted control trajectory if the validation is valid, and controls the wind turbine with a safe-mode control trajectory if the validation is invalid. In an embodiment, the main controller is implemented as a receding horizon controller, e.g. in the form of a model predictive controller (MPC).
