摘要： Systems and methods for providing override control for a feedwater pump recirculation valve are provided. According to one embodiment, a system may include a controller and a processor communicatively coupled to the controller. The processor may be configured to receive one or more measurements associated with pump motor power driving feedwater pump flow. The feedwater pump recirculation valve may be configured to maintain a predetermined minimum recirculation flow through the feedwater pump by regulating recirculation pump flow through a recirculation line. The processor may be also configured to calculate, based at least in part on the one or more measurements, the recirculation pump flow, and compare the recirculation pump flow to the predetermined minimum recirculation flow. Based at least in part on the comparing, the processor may selectively provide an override control signal to the feedwater pump recirculation valve to selectively modify the recirculation pump flow.

摘要： A system and method of managing notifications of a plurality of states of a plant of equipment are provided. The alarm system includes a memory device and one or more processors communicatively coupled to the memory device. The one or more processors are programmed to receive parameters relating to a potential alarm, receive an indication of a plant event from at least one of a plurality of field devices, compare the received indication to the received parameters, and display a notification of the potential alarm as at least one of an event, a diagnostic, an alert, and an alarm based on the comparison and in accordance with the received parameters.
