  • Method and system for detection and transfer to electrical island operation
    Patent number: 7457688
    Abstract: A method for transient fuel control for fuel delivery circuits for a plurality of connected gas turbines, the method includes: detecting a transient grid event based on an indication of at least one of a rapid change in a fuel command to the gas turbine or an acceleration of the turbine shaft; upon detection of the transient grid event, commanding a gas turbine controller to transfer the gas turbine to at least one intermediate load; adjusting a fuel split to maintain combustor stability during the transient grid event, and using a predetermined island load demand signal to apportion an island load demand among the connected gas turbine generators.
    Type: Grant
