Multi-Screen HMI for High Voltage Power System Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power transmission and distribution systems are limited in their ability to control and monitor multiple high voltage elements due to user interface constraints, which restrict the number of objects that can be handled on a single display, hindering efficient management and control of power systems.
Innovation Solution
The implementation of an intelligent electronic device with a human-machine interface that allows for the mapping of multiple high voltage power transmission and distribution system elements across multiple control screens, enabling simultaneous display and control of these elements through a graphical single line diagram, using a computer program product with executable instructions to facilitate this functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single-screen display is used to control power system elements, then the device complexity is reduced, but the number of controllable elements is limited
Solution Approach 1:
The user interface is segmented into multiple control screens, each dedicated to displaying and controlling specific elements of the power system. This segmentation allows the system to handle a larger number of controllable elements by distributing information across multiple screens rather than attempting to display everything on a single screen, thus resolving the contradiction between quantity of elements and interface complexity.
Solution Approach 2:
The system transitions from a two-dimensional single-screen display to a multi-dimensional interface by adding the dimension of multiple screens. This dimensional expansion enables the display of additional power system elements and their control functions across several screens, effectively increasing the capacity to handle complex power transmission and distribution systems.
2Ease of operation
If multiple elements are displayed on a single screen, then the display area utilization is improved, but the ease of operation deteriorates due to information overload
Solution Approach 1:
The control interface is segmented into multiple specialized screens, each handling specific power system elements. This segmentation reduces information overload on any single screen, making the system easier to operate while still providing comprehensive control capability across the entire power system through coordinated multi-screen interaction.
