Abstract
A combined cycle electric power plant includes gas and steam turbines and steam generators and a digital/analog control system. A surge protection system is included as part of the analog portion of the control system, and it functions in both automatic and manual modes of operation. A surge protection signal is generated to limit fuel demand as a function of speed during startup and as a function of combustor shell pressure during higher speed load operation.
