Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual analysis is used for transfer paths and risks, then specific load transfer tasks can be analyzed, but it cannot process multiple tasks simultaneously and requires re-analysis for each task change
Solution Approach 1:
The patent pre-calculates and stores risk values for all possible transfer paths between substations before actual load transfer tasks are executed. This preliminary computation creates a reusable risk database that can serve multiple transfer tasks without re-analysis, directly resolving the contradiction between processing efficiency and re-analysis time
Solution Approach 2:
The patent creates a universal risk assessment model that can evaluate multiple transfer tasks simultaneously using the same pre-computed risk values. This multi-functional approach allows the system to handle various load transfer scenarios without requiring separate analysis for each task, improving productivity while eliminating redundant time consumption
2Reliability
If design of load transfer control parameters is performed, then transfer control can be achieved, but it is very difficult to take path risk and switch risk into account at the same time
Solution Approach 1:
The patent merges path risk and switch risk into a unified risk assessment framework. By combining these previously separate risk factors into a single integrated model, the system can simultaneously consider both risks without increasing design complexity, thereby improving transfer control reliability
Solution Approach 2:
The patent transforms complex risk considerations into simplified quantitative parameters that can be directly incorporated into control decisions. By changing the representation of risk from qualitative assessments to standardized numerical values, the system maintains reliability while reducing parameter design complexity
3Measurement precision
If power flow reverse examination is performed, then accurate risk assessment can be achieved, but it is a very difficult task
Solution Approach 1:
The patent replaces complex mechanical power flow analysis with an equivalent electrical circuit model approach. By substituting the difficult power flow reverse examination with an analogous electrical system analysis, the patent achieves accurate risk assessment while significantly reducing the difficulty of detection and measurement
