Power Plant HMI Multi-Parameter Graphical Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power plant operators face challenges in monitoring and analyzing multiple parameters simultaneously due to the limited capability of existing human machine interface (HMI) screens, which only display data related to a single parameter at a time, hindering timely detection of malfunctions and process deviations.
Innovation Solution
A system and method that processes and graphically displays multiple power plant parameters on a single HMI screen by selecting and scaling relevant parameters, generating a graphical representation with a common axis range, allowing operators to view and compare multiple parameters simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple parameters are displayed on a single HMI screen, then operators can view and compare multiple parameters simultaneously, but the complexity of the display system increases
Solution Approach 1:
The display system segments parameters into different categories (primary parameters, secondary parameters, alarm parameters) and presents them in a hierarchical structure. This allows multiple parameters to be displayed simultaneously while maintaining organizational clarity and reducing visual complexity through structured presentation.
Solution Approach 2:
The system transitions from traditional single-parameter displays to a multi-dimensional graphical interface that accommodates multiple parameters across different spatial dimensions on the HMI screen. This enables simultaneous visualization of multiple parameters without linearly increasing display complexity.
2Reliability
If traditional HMI screens display only a single parameter, then the display system remains simple, but operators cannot detect malfunctions and process deviations timely
Solution Approach 1:
The system implements continuous monitoring and real-time feedback by displaying multiple parameters simultaneously on the HMI screen. This enables operators to immediately detect deviations and malfunctions across multiple parameters without sequential checking, reducing detection time and improving reliability through enhanced situational awareness.
Solution Approach 2:
The system prepares and displays relevant parameters in advance on the HMI screen, allowing operators to proactively monitor for potential issues before they escalate. This preliminary visualization of multiple parameters enables early detection and faster response to emerging problems.

AI summary
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.
