Abstract: A power generation system includes: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied, the first combustor arranged to supply hot combustion gases to the first turbine component, and the first integral compressor having a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A control valve system controls flow of the excess air flow from the first gas turbine system to the second gas turbine system. A cooling fluid injector may be coupled to the excess air flow path for injecting a cooling fluid such as water or steam into the excess air flow.

Abstract: A combined cycle power plant comprises a compressor, a combustion section including a compressor discharge casing which is disposed downstream from the compressor, a turbine disposed downstream from the combustion section and an exhaust duct disposed downstream from the turbine section. The compressor, the compressor discharge casing, the turbine and the exhaust duct define a primary flow passage through the gas turbine. A heat recovery steam generator is in thermal communication with the exhaust duct and in fluid communication with a steam turbine. A blower is in fluid communication with the primary flow passage upstream from the heat recovery steam generator such that the blower draws compressed air from the primary flow passage during turning gear operation of the gas turbine.

Abstract: A system and method is provided that improves the under frequency response of gas turbines by providing a fast-response power augmentation system. The system includes a tank storing a blended mixture of motive fuel such as ethanol or methanol and demineralized water in a predetermined ratio that is provided as a diluent to be injected into the compressor bellmouth, the Compressor Discharge Chamber (CDC), and/or the combustion system via one to three dedicated circuits. To achieve the instantaneous injection of the diluent at the correct pressure and for the appropriate duration to meet the needs of the gas turbine Grid compliance mandate, an accumulator is used as the motive force to drive the augmentation fluid in the dedicated circuits. The injected diluent is microprocessor controlled to either be simultaneous into all three circuits or is sequenced based on a determination of the best turbine control and performance.
