Centralized Controller for Power Distribution Safety and Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution systems face challenges in balancing safety for personnel working on energized equipment with the need to maintain continuous power supply, as current safety measures can disrupt the system and are not adequately coordinated across all parts of the power system.
Innovation Solution
A centralized controller system that determines and switches between normal and alternate mode configuration settings for circuit breakers, allowing for localized control and reduced energy let-through modes to enhance safety while minimizing system disruptions, using a user interface and communication units to manage circuit breaker operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If circuit breaker sensitivity is increased to improve safety for personnel working on energized equipment, then safety is improved, but the system becomes more prone to nuisance trips and disruptions
Solution Approach 1:
The system performs preliminary actions by pre-configuring alternate mode settings for circuit breakers before safety incidents occur. When a safety event is detected (such as door opening or motion detected), the system automatically switches to alternate modes that reduce power in affected areas, thereby preventing harmful effects while maintaining system continuity.
Solution Approach 2:
The system dynamically adjusts circuit breaker settings based on real-time conditions. By switching between normal mode and alternate mode configurations, the system adapts its protection sensitivity and power distribution dynamically, allowing high sensitivity when needed for safety while maintaining normal operation during standard conditions.
2Reliability
If localized safety measures are implemented to protect personnel, then safety is improved, but coordination with other parts of the power system is insufficient
Solution Approach 1:
The system merges localized safety measures with centralized control by implementing a master controller that coordinates multiple circuit breakers across the entire power distribution system. This unified approach ensures that safety actions in one area are properly coordinated with other parts of the system, preventing unintended disruptions while maintaining comprehensive safety.
Solution Approach 2:
The system employs feedback mechanisms where the master controller continuously monitors system conditions and automatically adjusts circuit breaker settings based on detected events. This feedback loop ensures real-time coordination across the power distribution system, allowing safety measures to be implemented while maintaining overall system stability and proper coordination.
3Reliability
If circuit breaker delays are added to meet safety standards, then safety is improved, but power continuity to non-faulted branches is reduced
Solution Approach 1:
The system applies local quality by implementing selective power reduction only in areas where safety risks are present. Instead of applying uniform delays or shutdowns across the entire system, the master controller identifies specific circuit breakers and zones that require safety measures, leaving other areas operating normally to maintain power continuity.
Solution Approach 2:
The system changes operational parameters by switching between different configuration modes for circuit breakers. When safety events are detected, parameters such as trip thresholds, delay times, and power levels are adjusted in affected areas, while non-affected areas maintain their normal operating parameters, thereby preserving power continuity.
