Abstract: A system and method are provided for controlling a wind turbine. Accordingly, a controller of the wind turbine detects a loss of traction of the slip coupling between a generator and a rotor of the drivetrain of the wind turbine. In response to detecting the loss of traction, the controller overrides a generator torque setpoint to alter a rotational speed of the generator. In response to the altered rotational speed of the generator, the traction of the slip coupling is increased. Increasing the traction of the slip coupling facilitates an application of generator torque to the drivetrain of the wind turbine.

Abstract: This disclosure describes a collective UAV in which multiple UAVs may be coupled together to form the collective UAV. A collective UAV may be used to aerially transport virtually any size, weight or quantity of items, travel longer distances, etc. For example, rather than using one large UAV to carry a larger or heavier item, multiple smaller UAVs may couple together to form a collective UAV that is used to carry the larger or heavier item.

Abstract: A system and method are provided for controlling a wind turbine to protect the wind turbine from anomalous operations. Accordingly, in response to receiving data indicative of an anomalous operational event of the wind turbine, the controller initiates an enhanced braking mode for the wind turbine. The enhanced braking mode is characterized by operating the generator at a torque setpoint that generates maximum available torque for a given set of operating conditions. Additionally, the torque setpoint is in excess of a nominal torque limit for the generator.

Abstract: A method for processing a data package to be sent to an addressed recipient. The method comprises obtaining payload data to be sent over a data network as a data package. The data package comprises the payload data and a header. The method also comprises analysing the header of the data package based on a plurality of characteristics, the header comprising at least an addressed recipient, and the characteristics comprising at least a recipient identifier and a transmission time. A risk indicator is generated, which indicates a risk associated with the analysis of the addressed recipient of the data package. The data package is processed to determine a handling action for the data package. The handling action is based on the risk indicator and is applied the handling action to the data package to generate a processed data package. The processed data package is then transmitted to the addressed recipient.
