Abstract:
A power generation system may include a generator; a gas turbine system for powering the generator, the gas turbine system including a turbine component, an integral compressor and a combustor to which air from the integral compressor and fuel are supplied, the combustor arranged to supply hot combustion gases to the turbine component, and the integral compressor having a flow capacity greater than an intake capacity of at least one of the combustor and the turbine component, creating an excess air flow. A first control valve system controls flow of the excess air flow along an excess air flow path to a supplemental gas turbine system. The excess air flow may be combusted with a fuel and supplied to the supplemental gas turbine system. An eductor may be positioned in the excess air flow path for using the excess air flow as a motive force to augment the excess air flow with additional gas.

The present application provides a multiple fuel delivery system for use with a gas turbine engine. The multiple fuel delivery system may include a first fuel tank with a first fuel therein, a second fuel tank with a second fuel therein, a mixing chamber, and a flow divider downstream of the mixing chamber. The first fuel tank may be in communication with the mixing chamber via a first fuel pump and the second fuel tank may be in communication with the mixing chamber via a second fuel pump.
Abstract:
A power generation system may include: 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 integral compressor has 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 turbo-expander may be operatively coupled to the second gas turbine system. Control valves may control flow of the excess air flow from the first gas turbine system to at least one of the second gas turbine system and the turbo-expander, and flow of a discharge of the turbo-expander to an inlet of at least one of the first integral compressor and the second compressor.

Abstract:
A gas turbine system includes a compressor protection subsystem; a hibernation mode subsystem; and a control subsystem that controls the compressor subsystem and the hibernation subsystem. At partial loads on the turbine system, the compressor protection subsystem maintains an air flow through a compressor at an airflow coefficient for the partial load above a minimum flow rate coefficient where aeromechanical stresses occur in the compressor. The air fuel ratio in a combustor is maintained where exhaust gas emission components from the turbine are maintained below a predetermined component emission level while operating at partial loads.
Abstract:
A power generation system includes one or more processors and memory storing instructions that cause the one or more processor to execute a series of steps. That is, the one or more processors receive data indicative of a plurality of inputs associated with the power generation system, such that the plurality of inputs include a flow rate of a valve coupled between an inlet of a compressor in the power generation system and an exhaust of the compressor, where the valve fluidly couples a first fluid exiting the exhaust of the compressor to the inlet of the compressor. Furthermore, the one or more processors determine one or more output parameters of the power generation system based on the plurality of inputs, determine whether the one or more output parameters are within one or more respective threshold values, determine one or more fuel schedule adjustments for the power generation system when the one or more output parameters are outside the one or more respective threshold values; and modify a fuel schedule for providing fuel to a combustor of the power generation system based on the one or more fuel schedule adjustments.
