Abstract
Embodiments of the disclosure relate to automatic switching of HMI (human-machine interface) screens based on process, task, and abnormal deviation in a power plant. According to one embodiment, a method is provided. The method can include monitoring one or more processes occurring during the operation of a turbine power plant in a steady state monitoring sequence, in which a plurality of overview screens are monitored, and at least one process state is determined. If the at least one process state indicates a predefined condition has occurred, at least one human interface screen can be presented to a user for troubleshooting, based at least in part on the severity of the predefined condition. If the determined process state does not indicate the predefined condition is present, and the at least one determined process state indicates an automated task sequence, the method present a sequence of preconfigured task screens to a user.
