Patent number: 10146219Abstract: 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.Type: GrantFiled: December 23, 2013Date of Patent: December 4, 2018Assignee: General Electric CompanyInventors: Venkatesh Mani Selvaraj, Nagesh Laxminarayana Kurella, Rohan Saraswat, Veera Paparao Bolla

Patent number: 9696697Abstract: 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.Type: GrantFiled: September 4, 2013Date of Patent: July 4, 2017Assignee: General Electric CompanyInventors: Rohan Saraswat, Nagesh Laxminarayana Kurella, Karthikeyan Loganathan

Patent number: 8832563Abstract: 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.Type: GrantFiled: July 27, 2011Date of Patent: September 9, 2014Assignee: General Electric CompanyInventors: Suresh Vure, Mark R. Phelps, Rohan Saraswat, Raja Balasubramaniam

Publication number: 20120210257Abstract: Systems and methods for analyzing and displaying power plant data are able to access continuous live and/or historical operational data and identify within the data: (a) instances of at least one given type of power plant operation, (b) key events that may occur during an instance of the at least one given type of power plant operation, and (c) one or more time-based segments based on the key events and a physical segmentation of the power plant. Performance aspects for selected identified power plant operation instances can be quantified by comparing the identified instances with metrics that are predefined relative to the key events and segmentation within each type of power plant operation. Selected data associated with the identified instances are provided as electronic output to a user.Type: ApplicationFiled: February 11, 2011Publication date: August 16, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: Matthew John Mosley, Christopher Eugene Long, Rohan Saraswat, Ratna Manedhar Punjala, Venkatesh Mani Selvaraj
