  • Publication number: 20240003334
    Abstract: Aspects of the present invention relate to a method for controlling one or more wind turbine generators. The method comprises: receiving a trigger signal, and implementing an active power boost mode during a predetermined time period in response to receiving the trigger signal. The active power boost mode comprises: disregarding further trigger signals; and generating one or more upper active power limits for each of the one or more wind turbine generators, wherein, during at least a first portion of the predetermined time period, the one or more upper active power limits are fixed at an active power boost level that is greater than a nominal active power level of the one or more wind turbine generators.

  • Publication number: 20230193874
    Abstract: A method is provided for determining a power production capacity of at least one wind turbine connected to a power grid. The method includes receiving, e.g. from a power grid control center, a power production forecast for the at least one wind turbine, and then monitoring an actual grid frequency of the power grid. Based on the actual grid frequency and a nominal grid frequency, a frequency support power reserve is determined.

  • Patent number: 4983967
    Abstract: A method of encoding an audio signal onto and decoding an audio signal from a video signal wherein, in the encoding stage, successive portions of the audio signal are sampled, time compressed and inserted in analogue form into predetermined lines in the vertical interval of each field of the video signal. Also, distortion cancelling signals (which are generated as inverted forms of the time compressed audio signal portions) are inserted in analogue form into further predetermined lines in the vertical interval of each field of the video signal. In the subsequent decoding stage, the successive audio signal portions and the distortion cancelling signals are separated from the video signal, and associated ones of the audio signal portions and the distortion cancelling signals are added after inverting either the audio signal portions or the distortion cancelling signals in order that any perturbation present in both signals will cancel to zero.
