Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If large volumes of operational and non-operational data are collected from various assets and monitoring equipment, then the value for monitoring and analyzing substation operation increases, but the difficulty of organizing and analyzing the data increases
Solution Approach 1:
The patent segments the large volume of substation data into distinct operational data and non-operational data categories, with further subdivisions into equipment condition information, analytical data, and ambient condition information. This segmentation allows the system to organize and analyze different data types using appropriate methods, reducing the overall complexity of data management while preserving the full value of collected information
Solution Approach 2:
The patent introduces an intermediary data processing layer that sits between data collection from field devices and the final analysis system. This intermediary layer standardizes and structures the diverse data formats from multiple sources, transforming raw data into organized information that can be efficiently analyzed without losing valuable insights
2Reliability
If comprehensive monitoring and diagnostic functions are implemented, then maintenance and repair optimization improves, but system complexity increases
Solution Approach 1:
The patent implements a universal monitoring and diagnostic system that handles multiple functions through integrated components. The system simultaneously performs data collection, data organization, condition monitoring, diagnostic analysis, and maintenance scheduling across various substation assets using a common platform, reducing overall system complexity compared to implementing separate specialized systems for each function
Solution Approach 2:
The monitoring and diagnostic system is designed to automatically analyze equipment condition data and generate maintenance recommendations without requiring constant human intervention. The system self-manages data processing, identifies equipment issues, and provides actionable insights, reducing the operational complexity of managing comprehensive monitoring functions
