Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If matrix based representation is used to present CA results, then comprehensive data coverage is achieved, but visual feedback of transmission elements is lost and operator comprehension becomes difficult
Solution Approach 1:
The patent transitions from traditional matrix-based 2D representation to a 3D geographical visualization of the utility network. This dimensional change allows operators to view contingency analysis results in the context of the actual physical layout, maintaining comprehensive data coverage while dramatically improving visual feedback and comprehension through spatial relationships and geographical correlation.
Solution Approach 2:
The patent creates a visual copy of the utility network's geographical layout and overlays contingency analysis results directly onto this copy. This allows operators to see risk indicators positioned exactly where they would appear on the actual network, providing intuitive visual feedback without losing any analytical data.
2Ease of manufacture
If 2D representation with size or color changes is used to show impacted elements, then visual feedback is provided, but geographical correlation is lost and comprehension remains difficult
Solution Approach 1:
The patent enhances 2D visual feedback by incorporating 3D geographical positioning. Risk indicators are not just displayed on a flat diagram but are positioned according to the actual geographical coordinates of transmission elements, restoring geographical correlation while maintaining visual feedback through size and color variations.
Solution Approach 2:
The patent introduces geographical information as an intermediary layer between the visual representation and the actual network layout. This intermediary maintains the visual feedback mechanism while simultaneously restoring geographical correlation by anchoring all visual elements to their true spatial positions.
3Loss of information
If 3D visualizations are used to present CA results, then comprehensive data is displayed, but the representation becomes confusing and difficult to comprehend
Solution Approach 1:
The patent applies local quality by providing detailed 3D visual information at specific geographical locations while maintaining overall network context. Each transmission element is visualized with appropriate detail and risk indicators localized to their specific positions, preventing information overload while ensuring comprehensive data display.
Solution Approach 2:
The patent segments the complex 3D visualization into manageable components - individual transmission elements, localized risk indicators, and hierarchical levels of detail. This segmentation allows operators to focus on specific areas of interest without being overwhelmed by the entire network's complexity, improving comprehension while maintaining comprehensive data availability.
Data Source
AI summary
A method for use in monitoring a utility network includes identifying, via a computing device, at least one contingent performance violation associated with a first element of a plurality of transmission elements of a utility network. The method includes presenting by the computing device a risk indicator corresponding to the contingent performance violation around a graphical representation of the first element.
