Substation Interface Linking Rules for Hierarchical Model Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating or updating hierarchical models of power utility assets, such as substation automation systems, are complex and error-prone, especially when modeling interconnecting structures on higher hierarchy levels and displaying them on lower hierarchy level views.
Innovation Solution
The use of linking rules that define the connection of objects at lower hierarchy levels to objects at higher hierarchy levels, allowing for topologically correct modeling and automatic display of interconnecting structures even on lower hierarchy level views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If interconnecting structures are modeled on higher hierarchy levels, then the hierarchical model structure is maintained, but the complexity of generating and updating the model increases
Solution Approach 1:
The patent introduces an intermediary mechanism that automatically projects interconnecting structures from higher hierarchy levels to lower hierarchy level views. This mediator handles the complex mapping relationships between hierarchy levels, eliminating the need for manual piecewise modeling while preserving the stable hierarchical structure.
Solution Approach 2:
The patent segments the display of interconnecting structures by hierarchy level, allowing the same interconnecting structure to be displayed appropriately in both higher and lower hierarchy level views through automatic projection, rather than requiring separate manual modeling at each level.
2Stability of the object's composition
If piecewise modeling of interconnecting structures is used, then the hierarchical structure is preserved, but errors increase and intuitiveness decreases
Solution Approach 1:
The automatic projection mechanism acts as an intermediary that ensures consistent and accurate representation of interconnecting structures across hierarchy levels, eliminating manual errors while preserving the hierarchical structure.
Solution Approach 2:
The patent creates projected representations of interconnecting structures at lower hierarchy levels based on the master definition at higher levels. These projections are automatic copies that maintain topological correctness without requiring manual recreation, thus improving reliability.
3Ease of operation
If fake graphical representations are displayed in Bay views, then the display is simplified, but correctness of connections is compromised
Solution Approach 1:
The automatic projection mechanism serves as an intermediary that generates accurate graphical representations of interconnecting structures in Bay views based on the hierarchical model data, replacing fake graphics with topologically correct displays while maintaining ease of operation.
4Adaptability or versatility
If manual configuration methods are used, then flexibility is maintained, but the risk of errors increases
Solution Approach 1:
The system performs self-service by automatically projecting interconnecting structures and maintaining their topological relationships across hierarchy levels. This automation reduces human error while preserving configuration flexibility through the underlying adaptable hierarchical model structure.

AI summary
A device uses linking rules to process and optionally update a hierarchical substation model of a power system substation. The linking rules determine to which substation object at a first hierarchy level substation objects at a further hierarchy level of the hierarchical substation model are to be connected.
