摘要： A system and process for restarting a turbomachine includes a shutdown cooldown protection process implemented by a plant level control system or direct control system of the turbomachine. The system and process for restarting ensure rotating components are cooled as expected prior to a unit restart. This system and process for restarting will lockout an ability to restart if an improper cooldown of rotating components is detected. If this lockout is enabled, delaying restart for the rotating components to cool naturally is needed, or the operator could decide to force cool the components.

摘要： Systems and methods for avoidance and correction of potentially adverse combustion states such as flame holding and flashback are disclosed. According to one embodiment of the disclosure, one or more sensors acquire sensor data from one or more sensors associated with combustion. An operational limit margin (OLM) is calculated using an OLM model and based at least in part on the sensor data. A determination is made as to the presence of a potentially adverse combustion state based at least in part on the OLM and the model. Once determined, corrective action may be taken to avoid an adverse combustion event prior to occurrence of the event.
