1. A method of managing operation of a power plant, comprising:

  • monitoring, by a controller, via a plurality of sensors operable to sense parameters associated with one or more processes, the 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 determined process state indicates a predefined condition is present, then at least one human interface screen is output to a user for troubleshooting, based at least in part on severity of the predefined condition, the at least one human machine interface screen conveying information related to operational status of components of the turbine power plant, the at least one human machine interface screen comprising operational controls to allow a user to take control of the one or more monitored processes; and

    if the determined process state does not indicate the predefined condition is present, and if the at least one determined process state indicates an automated task sequence, then outputting a sequence of preconfigured task screens to a user, wherein the automated task sequence includes at least one task performed by the turbine power plant, the at least one task including a plurality of sub-tasks being performed by the turbine power plant, each sub-task being associated with a human machine interface task screen, wherein the outputting the sequence of preconfigured task screens includes outputting a plurality of human machine interface task screens, each human machine interface task screen being output in a sequential manner based at least on a predefined rank associated with each of the plurality of sub-tasks.
