Solution Overview
Problem
Electricity suppliers face challenges in timely detection and localization of abnormal conditions and electrical faults in electrical grids, leading to potential wide-area power outages due to insufficient information and difficulty in determining the location of faults within vast networks.
Innovation Solution
A system utilizing an Internet Protocol (IP) backplane with Session Initiation Protocol (SIP) for efficient communication between utilities and electrical devices, enabling real-time monitoring and control through a Supervisory Control and Data Acquisition (SCADA) system, which displays alerts and status information in geo-spatial, schematic, or tabular views to facilitate prompt action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional electrical grid monitoring systems are used, then system simplicity is maintained, but fault detection speed and localization accuracy deteriorate
Solution Approach 1:
The patent segments the electrical grid into multiple zones with dedicated monitoring devices at strategic locations. Each monitoring device independently tracks electrical parameters in its specific zone, enabling parallel fault detection across the grid. This segmentation allows rapid localization of faults to specific zones without requiring a single complex centralized system to process all data sequentially.
Solution Approach 2:
The patent introduces a communication network as an intermediary between monitoring devices and the central control system. This intermediary enables real-time transmission of electrical parameter data and fault information across the grid, significantly speeding up fault detection and localization. The communication network acts as a mediator that connects distributed monitoring points without requiring direct physical connections to the central system.
2Measurement precision
If comprehensive monitoring of all electrical devices is implemented, then fault localization accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent implements local quality by equipping specific electrical devices or zones with dedicated monitoring capabilities based on their criticality and fault risk. Rather than uniformly monitoring all devices with identical complexity, the system applies enhanced monitoring precision to high-priority areas while using simpler monitoring for less critical components. This approach achieves accurate fault localization in key areas without overwhelming the system with uniform complex processing across all devices.
Solution Approach 2:
The patent divides the electrical grid into multiple manageable zones or segments, each with its own monitoring and analysis capabilities. This segmentation allows the system to process electrical parameter data in distributed units rather than as one overwhelming data stream. Each segment can independently identify and report anomalies, reducing the processing burden on any single system component while maintaining comprehensive coverage.
3Reliability
If real-time monitoring of electrical parameters is implemented, then power outage prevention capability is improved, but system resource consumption increases
Solution Approach 1:
The patent implements periodic monitoring of electrical parameters at strategically selected locations and intervals. Rather than continuously monitoring all parameters at all locations simultaneously, the system periodically samples electrical data from multiple points, analyzing trends over time. This periodic approach maintains the ability to detect developing faults and prevent power outages while significantly reducing the energy consumption and computational resources required compared to continuous full-grid monitoring.
