  • Publication number: 20220247647
    Abstract: A plurality of flow logs associated with a plurality of computing units are aggregated. For each flow event included in the plurality of flow logs a corresponding namespace with which the flow event is associated is determined including by determining a corresponding intermediary associated with the flow event.

  • Publication number: 20220112879
    Abstract: Aspects of the present invention relate to controlling a wind turbine having a tower damping system actuable to control components of vibrational movement of the tower, a side-side component of a vibrational movement of the tower in a horizontal plane; and a fore-aft component of the vibrational movement of the tower in the horizontal plane are determined; and a control signal based on the side-side and fore-aft components is determined such that the tower damping system produces a force that increases or decreases the vibrational movement of the tower such that the side-side and fore-aft components are substantially equal.

  • Patent number: 11300099
    Abstract: A wind turbine controller includes a thrust limiter for controlling the thrust of the blades of wind turbine using an estimate of the air density at the wind turbine. In one embodiment, the controller receives the blade flap load indicating the current load on one of the blades which varies linearly to the air density experienced by the wind turbine. In one embodiment, the controller determines the mean of a plurality of the blade flap load values measured during a predefined time period. Using a transfer function, the controller converts the mean of the blade flap loads to an estimate of the air density at the turbine. Generally, higher air density results in greater loads on the blades while lower air density results in lower loads on the blades.

  • Publication number: 20220082085
    Abstract: The invention relates to a method for determining power set points of a power plant comprising a plurality of power generating units with at least one wind turbine generator. The determination of the power set points are based on a prioritization of the power generating units, where the power generating units are prioritized with respect to individual power levels or fatigue levels obtained for the power generating units. The prioritization is adjusted so that the adjusted prioritization depends both on the power and fatigue levels.

  • Patent number: 7560669
    Abstract: A method of thermal treatment of components. The optimum thermal amplitude of the components at which the phase transformation kinetics of the components is maximum is determined by subjecting samples of the components to cyclic thermal processing at various thermal amplitudes by maintaining the upper temperature constant and varying the lower temperature. A thermal amplitude which is higher than the optimum thermal amplitude is selected. The components are subjected to cyclic thermal processing at the thermal amplitude selected above to achieve near uniform phase transformation kinetics of the components across their crosssection. The components are cooled down to room temperature to obtain components with near uniform microstructure and properties.
