Abstract
A system includes a controller including a memory storing instructions to perform operations of a power generation system and a processor that executes the instructions. The instructions cause the controller to control purging fluid flow to an inlet of a gas turbine, an exhaust of the gas turbine, or a combustion section of the gas turbine. The instructions cause the controller to receive a first temperature at the inlet, a rotational speed of the gas turbine, and a purging fluid flow rate. The instructions cause the controller to calculate an exhaust flow rate of the system based on at least the first temperature, the rotational speed, and the purging fluid flow rate. The instructions cause the controller to control the system to isolate a fuel source from the gas turbine at a portion of normal operating speed sufficient to achieve a purging volume during coast down.
