  • Gas turbine water wash methods and systems
    Patent number: 10041373
    Abstract: A control system for a gas turbine includes a controller. The controller includes a processor configured to access an operational parameter associated with the gas turbine. The processor is configured to receive a plurality of signals from sensors disposed in a turbine system, wherein the turbine system comprises a compressor system. The processor is further configured to derive a compressor efficiency and a turbine heat rate based on the plurality of signals. The processor is additionally configured to determine if an online water wash, an offline water wash, or a combination thereof, should be executed. If the processor determines that the online water wash, the offline water wash, or the combination thereof, should be executed, then the processor is configured to execute the online water wash, the offline water wash, or the combination thereof.

  • Method and apparatus for receiving and tracking phase modulated signals
    Patent number: 4455680
    Abstract: A receiver for tracking and demodulating several types of phase modulated communications, either analog or digital data, for either residual carrier or suppressed carrier signal and for phase modulation or keying of two, four or higher phase angles, from 0.degree. through 360.degree.. A carrier component signal and a converted series sideband component signal are obtained from the incoming signal and summed to produce a carrier tracking signal, permitting more accurate tracking of the above types of phase modulated data.
