Interactive Fault Diagnosis Interface for Power Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power system monitoring systems only present the final diagnosis of faults to users, without showing the actual measurements and variables that facilitate the diagnosis, and lack an interactive platform for further analysis.
Innovation Solution
A computing device that processes data from sensors in power systems, generates a graphical representation of fault data, and provides an interactive interface for users to select and analyze specific measurements and variables, enabling detailed fault diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the final diagnosis is presented to the user, then the information presentation is simple and direct, but the user cannot see the actual measurements and variables that facilitate the diagnosis
Solution Approach 1:
The patent segments the diagnostic information into multiple hierarchical levels: summary-level fault diagnoses and detailed-level measurements/variables. Users can access different levels of detail based on their needs, preserving comprehensive information while maintaining presentation simplicity through structured organization of data at different granularities.
Solution Approach 2:
The patent adds a temporal dimension to data presentation by showing both real-time measurements and historical trends. This allows users to view diagnostic information not just as static final results but as dynamic evolving data across time, enabling them to trace the development of faults and understand the diagnostic reasoning process.
2Ease of operation
If comprehensive measurement data is displayed to enable fault identification, then the user can see actual measurements and variables, but the data presentation becomes complex and difficult to navigate
Solution Approach 1:
The patent implements a dynamic interface that adapts to user interactions. The system allows users to drill down from summary views to detailed measurements on demand, and to filter or highlight specific data based on selected faults. This dynamic adaptability maintains ease of operation by presenting only relevant information at each interaction level while preserving access to comprehensive data.
Solution Approach 2:
The patent introduces an intermediary layer between the raw measurement data and the user interface - a structured data organization system that groups measurements by component, fault type, and temporal patterns. This intermediary structure simplifies navigation by providing logical categories and hierarchical organization, making comprehensive data manageable without losing detail.
3Adaptability or versatility
If an interactive platform is provided for selecting measurements and variables, then the user can perform detailed analysis, but the system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where user selections and interactions with the interface provide real-time updates and confirmations. When users select specific measurements or variables for analysis, the system responds by highlighting relevant data, adjusting displays, and providing contextual information. This feedback loop enhances adaptability by making the system responsive to user needs while managing complexity through automated response generation based on predefined analysis rules.
