A gas turbine is solidly coupled with rigid couplings in tandem with a reheat steam turbine and utilizes the combined inertia of the rotating members and the braking torque of the gas turbine air compressor to assist a single control system to limit overspeed of the complete unit. In its broadest and preferred form, the normal intercept steam valves and reheat stop valve between the reheater and the lower pressure steam turbine sections are eliminated, and the high pressure steam control valves are used to prevent overspeed, with steam flowing through a ...
A method for achieving overspeed protection in a combined cycle gas and steam turbine power plant, said method comprising the steps of: solidly coupling together to rotate at all times as a single rotor unit, including during sudden loss of load occurrences, the rotating members of a gas turbine with its associated combustor and air compressor, a high pressure steam turbine, at least one lower pressure stream turbine and an electrical generator; transferring heat from the gas turbine exhaust to steam exhausted from said high pressure steam turbine in a s...
