Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current computerized systems for managing electric power distribution grids are used, then data collection and remote management capabilities are provided, but the systems become complex and expensive with limited configurability
Solution Approach 1:
The accessory device automatically performs self-configuration by reading its serial number from memory, generating configuration files with default parameters, and transmitting them to the publishing computerized unit without requiring manual user input. This eliminates complex configuration procedures while maintaining adaptability.
Solution Approach 2:
The configuration files are pre-generated with default parameters during manufacturing or initial setup, stored in the accessory device's memory, and automatically transmitted when needed. This preliminary preparation eliminates the need for complex real-time configuration by users.
2Reliability
If advanced monitoring services are implemented using data from protection relays, then monitoring capabilities are improved, but the cost and complexity of the system increase
Solution Approach 1:
The system is divided into independent functional modules: accessory devices for data collection at the grid level, publishing computerized units for data reception and processing, and optional configuration computerized units. This segmentation allows advanced monitoring to be implemented incrementally without requiring complete system replacement.
Solution Approach 2:
The accessory device serves multiple functions: collecting data from protection relays, storing configuration parameters, generating configuration files, and transmitting data over the Internet. The publishing computerized unit handles data reception, storage, and processing. This multi-functionality reduces the number of separate components needed.
3Manufacturing precision
If manual configuration procedures are used for accessory devices, then configuration precision can be maintained, but the ease of operation and installation is reduced
Solution Approach 1:
The accessory device automatically reads its serial number from onboard memory, generates configuration files with appropriate parameters based on this identifier, and transmits them to the publishing computerized unit. This self-service approach maintains configuration precision while eliminating manual intervention.
Solution Approach 2:
Configuration files serve as an intermediary between the accessory device and the publishing computerized unit. The accessory device generates these files with precise configuration parameters, and they are automatically transmitted and processed, eliminating the need for manual configuration while maintaining precision.
