Abstract: A system includes a controller including a memory storing instructions and a processor that executes the instructions. The instructions cause the controller to receive a first input signal of a first temperature at an inlet of a gas turbine of a gas turbine and heat recovery steam generator (HRSG) system and a second input signal of a rotational speed of the gas turbine. The instructions also cause the controller to calculate the exhaust flow rate of the gas turbine and HRSG system based on the first input signal and the second input signal. Further, the instructions cause the controller to control the gas turbine and HRSG system to isolate a fuel source 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 gas turbine and HRSG system based on the exhaust flow rate.

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 method of controlling purge flow in a gas turbomachine system includes detecting a fault condition in the gas turbomachine system, initiating a shutdown of the gas turbomachine system, introducing a purge flow into a gas turbine portion of the gas turbomachine system, categorizing the fault condition as one of a category one fault and a category two fault, and validating the purge flow if the fault condition is a category one fault and invalidating the purge flow if the fault condition is a category two fault.
Abstract translation: 一种控制气体涡轮机系统中的吹扫流量的方法包括检测气体涡轮机系统中的故障状况，启动气体涡轮机系统的关闭，将吹扫流引入气体涡轮机系统的燃气涡轮部分，将故障状态 作为第一类故障和第二类故障之一，如果故障状态是第一类故障，则验证清除流量，如果故障状态是第二类故障，则使排气流无效。
