Abstract: A power generation system includes a 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 an exhaust of the turbine component. A selective catalytic reduction (SCR) unit may be coupled to an exhaust of the turbine component, the SCR unit receiving the exhaust and the excess air flow. 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 air, creating an augmented excess air flow.

Abstract: A system includes a controller of a power generation system including a memory storing instructions and a processor that executes the instructions. The instructions cause the controller to control the power generation system to provide inlet bleed heat flow to a gas turbine during deceleration of the gas turbine. The instructions also cause the controller to receive a first temperature, a rotational speed of the gas turbine, and an inlet bleed heat flow rate. Additionally, the instructions cause the controller to calculate an exhaust flow rate based on at least the first temperature, the rotational speed, and the inlet bleed heat flow rate. Further, the instructions cause the controller to control the power generation system to isolate a fuel source from the gas turbine at a portion of normal operating speed of the gas turbine sufficient to achieve a purging volume during coast down of the gas turbine.

Abstract: A system includes a controller including a memory storing instructions and a processor that executes the instructions. The instructions cause the controller to control a steam turbine system coupled to a power generation system to release steam during deceleration of a gas turbine. The instructions cause the controller to receive a first temperature of the gas turbine and a rotational speed of the gas turbine. The instructions cause the controller to calculate an exhaust flow rate of the power generation system based on at least the first input signal and the second input signal. The instructions cause the controller to control the power generation system to isolate a fuel source from the gas turbine at a portion of normal operating speed of the gas turbine sufficient to achieve a predetermined purging volume during coast down of air flow through the power generation system based on the exhaust flow rate.
