  • Patent number: 10127183
    Abstract: A device is configured to operate in an industrial automation environment. The device includes a processing unit, a memory, an industrial communication interface to communicate with an external device via an industrial communication protocol, and a serial peripheral interface to communicate with a peripheral board during operation of the device. The device is configured to receive configuration data related to an industrial automation function of the device via the serial peripheral interface and store the received configuration data in the memory, when the serial peripheral interface is coupled to an external memory device. When the serial peripheral interface is coupled to the peripheral board, the device is configured to operate to perform the industrial automation function, in accordance with the received configuration data.

  • Patent number: 10088838
    Abstract: A method for diagnostic monitoring of a wind turbine generator system, said wind turbine generator system comprising a generator, a drive train, and a number of sensors for providing signals and a control system. The method comprising the selection of three sets of signals from said sensors. From the three sets of signals three conditioned sets of signals are obtained by high pass filtering said first set of signals, low pass filtering the second set of signals, and forming a moving average value on the third set of signals. Based on each of said first, second and third set of conditioned signals an evaluation is performed in order to determine a fault, where said evaluation comprises comparing the first, second and third set of conditioned signals with reference values. If said comparison indicates a fault an alarm is set.

  • Patent number: 9347434
    Abstract: A wind turbine is provided. The wind turbine comprises a generator, a power converter for converting at least a portion of electrical power generated by the generator, an energy dissipating unit and a controller. The power converter comprises a generator-side converter, a grid-side converter and a DC (direct current) link there between. The energy dissipating unit is operatively coupled to the DC-link. The controller is adapted to activate the energy dissipating unit to dissipate energy from the DC-link in response to a shutdown request.
