Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processes are used for protection relay settings upload and download, then device complexity is reduced, but productivity decreases and loss of time increases
Solution Approach 1:
The patent replaces manual mechanical processes (physical relay settings adjustment, manual data entry) with automated digital systems. The system automatically uploads and downloads protection relay settings through digital communication protocols, eliminating the need for manual intervention and significantly improving productivity while reducing time loss.
Solution Approach 2:
The system enables self-service functionality where protection relays can automatically update their own settings based on received commands, and automatically report their status and disturbance records. This eliminates the need for manual configuration and retrieval processes, enhancing productivity without proportionally increasing system complexity.
2Reliability
If a centralized protection relay database is implemented, then loss of information is reduced and reliability is improved, but device complexity increases
Solution Approach 1:
The centralized database serves multiple functions: storing protection relay settings, recording disturbance events, maintaining asset information, and supporting both operational and engineering activities. This multi-functional approach consolidates what would otherwise require separate systems, improving reliability through centralized data management while limiting the increase in complexity through functional integration.
Solution Approach 2:
The centralized database acts as an intermediary layer between field devices and management systems. It standardizes data collection and storage formats, enabling seamless integration with various power system simulation tools and asset management systems without requiring complex point-to-point connections, thus improving reliability while managing complexity.
3Measurement precision
If digital twin representation of actual asset information is created, then loss of information is reduced and measurement precision is improved, but device complexity increases
Solution Approach 1:
The system creates digital copies (digital twins) of physical protection relays and power system assets that mirror their actual state and parameters. These digital representations accurately reflect real-time asset information, disturbance records, and operational status, improving measurement precision and information availability while using standard digital modeling techniques to manage complexity.
4Productivity
If integration of asset management system with power system simulation is implemented, then productivity is improved and loss of time is reduced, but device complexity increases
Solution Approach 1:
The patent merges asset management system functionalities with power system simulation capabilities into an integrated platform. This combination allows simultaneous access to asset data, protection settings, and simulation analysis tools, improving productivity by eliminating the need to switch between separate systems while using standardized integration interfaces to manage complexity.
