Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If power distribution is monitored only in rough units of high-voltage and low-voltage systems, then device complexity is reduced, but measurement precision deteriorates and abnormalities in smaller units are overlooked
Solution Approach 1:
The patent segments the power distribution system into multiple hierarchical levels: high-voltage system level, low-voltage system level, and individual facility level. The search unit divides the monitoring task by systematically investigating junctions and facilities in a segmented manner, allowing precise monitoring at each level while maintaining overall system manageability. This segmentation enables the system to detect abnormalities at any hierarchical level without requiring a single complex monolithic monitoring structure.
2Measurement precision
If detailed investigation of all junctions and facilities is performed, then measurement precision is improved, but productivity deteriorates due to increased investigation time
Solution Approach 1:
The search unit performs preliminary actions by systematically investigating junctions and facilities in a predetermined sequence before full monitoring is required. The electrical connection storage unit pre-stores the hierarchical structure and connection information, allowing the search unit to quickly navigate and identify target facilities without performing exhaustive investigations in real-time. This preliminary organization of data enables efficient retrieval and monitoring when needed.
Solution Approach 2:
The monitoring system dynamically adjusts its investigation scope and depth based on the current monitoring needs and system state. The search unit can selectively investigate specific junctions and facilities rather than uniformly monitoring everything at maximum detail. This dynamic approach allows the system to maintain high measurement precision for critical areas while reducing investigation overhead in stable areas, thereby improving overall productivity.
3Adaptability or versatility
If reverse power flow from distributed power sources is considered, then adaptability is improved, but device complexity increases due to bidirectional power flow management
Solution Approach 1:
The search unit and electrical connection storage unit are designed with universal functionality that handles both unidirectional and bidirectional power flows. The system structure can accommodate distributed power sources by simply activating the reverse power flow detection capability already present in the hierarchical monitoring framework. The same search mechanism that investigates facilities from the high-voltage side can equally investigate from the low-voltage side when reverse power flow occurs, eliminating the need for separate specialized systems.

AI summary
A power distribution management apparatus (10) stores electrical connection information in which a combination of a plurality of junctions at which a plurality of facilities of a power distribution system are electrically connected to each other and a facility determined based on the combination are associated, and searches a facility corresponding to the combination while investigating an uninvestigated junction among the plurality of junctions contained in the combination starting from a predetermined junction with reference to the electrical connection information, and acquires a display scale for displaying the power distribution system, and displays a facility having a junction near a substation from a predetermined facility among the facilities obtained as a result of the searching when the scale is equal to or less than a predetermined scale, and displays a facility obtained as a result of the searching when the scale is larger than the predetermined scale.
