This disclosure relates to systems and methods for processing and graphically displaying power plant data. In one embodiment, one or more values corresponding to one or more parameters associated with the performance of one or more power plant components may be received. A subset of the parameters associated with one or more operational characteristics based in part on the values may be determined. One or more display parameters may be selected that includes inputting at least a numerical range associated with at least one axis. The one or more parameter values in the subset may be scaled based in part on the inputted numerical range. A graphical representation may be generated and output on a graphical user interface that includes the one or more values within the numerical range on the at least one axis corresponding to each parameters in the subset based in part on the one or more display parameters.

Systems and methods for processing and graphically displaying power plant data

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.

A control system, in one embodiment, includes a plurality of controllers. Each of the plurality of controllers is configured to provide process data to a human-machine interface (HMI) client when selected as a designated controller. A first controller of the plurality of controllers is a current designated controller and is configured to communicate with the HMI client. The control system also includes designated controller selection logic configured to detect an interruption in communication between the current designated controller and the HMI client, poll each of the plurality of controllers for a response, determine which of the plurality of controllers responds first, and select the controller that responds first as the next designated controller.

A method for forecasting a start period for a combined cycle power generation system including a gas turbine engine, a steam turbine and a computer control system, the method including: inputting a desired time at which the power generation system is to reach a dispatchable load; inputting a current value of a predetermined operational condition of the power generation system; the computer control system retrieving historical data relating the predetermined operational condition to prior start periods of the power generation system or a similar power generation system; the computer control system executing an algorithm which generates a forecasted start time based on the desired time, current value and the retrieve data, wherein the power generation system is predicted to reach the dispatchable load at the desired time when started at the forecasted start time, and the computer system outputting the forecasted start time to the output device.
