Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing monitoring systems for electrical power grids are costly, require technical skill and labor, and are primarily reactive, failing to predict and prevent equipment failures that lead to widespread power outages due to the lack of real-time condition monitoring of structural elements and conductors.
Innovation Solution
A system comprising a detector alert assemblage with sensors, a computer controllable radio receiver, and a GPS for detecting and locating incipient faults in structural components of the electrical power delivery system, using signal propagation and impedance measurement to classify fault probabilities and submit data for predictive maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional monitoring systems are used for electrical power grids, then equipment failures can be detected, but the systems are costly and require technical skill and labor
Solution Approach 1:
The system enables structures to self-report their condition through embedded sensors that automatically detect and communicate structural health data, eliminating the need for manual inspections and reducing technical labor requirements while maintaining reliable failure detection
Solution Approach 2:
The patent replaces manual mechanical inspection systems with automated electronic sensing and communication systems, substituting human labor and technical expertise with self-monitoring infrastructure that continuously tracks structural conditions
2Reliability
If traditional monitoring systems are used, then some equipment failures can be detected, but they are primarily reactive and fail to predict and prevent equipment failures
Solution Approach 1:
The system performs preliminary actions by continuously monitoring structural parameters and identifying early signs of deterioration before failures occur, enabling predictive maintenance and preventing equipment failures rather than merely reacting to them after they happen
Solution Approach 2:
The patent implements continuous feedback loops where sensor data is constantly analyzed, compared against threshold values, and used to trigger alerts or maintenance actions, creating a closed-loop system that adapts to changing structural conditions and predicts failures before they occur
3Reliability
If comprehensive monitoring of all structures is implemented, then grid reliability improves, but the cost and complexity of the monitoring system increases
Solution Approach 1:
The system divides the extensive transmission infrastructure into discrete monitorable segments, with each structure equipped with its own sensor suite, allowing selective deployment based on criticality and enabling scalable implementation that balances comprehensive monitoring with cost constraints
Solution Approach 2:
The patent employs universal sensor platforms and communication protocols that can be deployed across diverse structure types (towers, poles, supports), reducing overall system complexity and cost through standardized components while maintaining the ability to monitor the entire grid infrastructure
