Intelligent Circuit Breaker Dynamic Coordination System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circuit breakers lack a proactive correction mechanism for incorrect configuration settings and fail to alert users of potential trip events, leading to nuisance tripping, operational losses, and downtime due to manual intervention requirements.
Innovation Solution
A dynamic coordination system within intelligent circuit breakers that monitors real-time data, identifies necessary configuration adjustments, and transmits alerts to users, enabling remote or manual adjustments without system shutdowns, using existing communication modules and energy monitoring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to adjust trip unit settings of circuit breakers, then coordination among circuit breakers can be established, but operational losses and downtime increase due to manual intervention requirements
Solution Approach 1:
The system enables circuit breakers to automatically detect configuration issues, identify coordination problems, and alert operators without requiring manual inspection or intervention. The circuit breakers self-diagnose their settings and communicate status, eliminating the need for operators to manually check and adjust trip unit settings during normal operation.
Solution Approach 2:
The system proactively identifies configuration errors and coordination issues before they cause nuisance tripping or system-wide blackouts. By continuously monitoring and comparing trip unit settings against system requirements, the system alerts operators in advance, allowing them to make adjustments during scheduled maintenance rather than during operational disruptions.
2Device complexity
If conventional circuit breakers are used without proactive correction mechanisms, then device complexity is reduced, but nuisance tripping occurs due to wrong setting configuration
Solution Approach 1:
The system incorporates continuous monitoring of trip unit settings and system conditions, comparing actual configurations against required coordination parameters. When discrepancies are detected, the system provides feedback to operators through alerts and notifications, enabling correction of configuration errors before they cause nuisance tripping. This feedback loop maintains high trip accuracy without requiring complex mechanical or electronic correction mechanisms within the circuit breaker itself.
3Ease of operation
If manual adjustment of trip unit settings is performed, then incorrect configuration can be corrected, but system shutdown is required leading to productivity loss
Solution Approach 1:
The system performs continuous automated monitoring and identification of configuration issues during normal system operation. By detecting and alerting operators to problematic settings in advance, the system enables adjustments to be made during scheduled maintenance windows rather than requiring emergency shutdowns to correct configuration errors, thereby maintaining production continuity.
Solution Approach 2:
The circuit breakers automatically monitor their own configuration settings and communicate status to operators without requiring system shutdown or manual intervention during normal operation. This self-diagnosis capability allows operators to plan and execute configuration adjustments during scheduled maintenance rather than forcing unplanned production stoppages.
4Reliability
If circuit breaker coordination is implemented, then system-wide blackouts are avoided, but identifying fault source and location remains challenging
Solution Approach 1:
The system continuously monitors trip unit settings, operational status, and system conditions across all circuit breakers, providing real-time feedback to operators. When faults or coordination issues occur, the system identifies and communicates the specific location and nature of the problem, enabling rapid fault isolation and resolution while maintaining system-wide coordination to prevent cascading failures.
