Circuit Breaker Error Correction via Weighted State Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In energy management systems, the large number of circuit breakers and disconnecting switches requires inefficient and unreliable error correction methods, as existing inconsistency inspections are labor-intensive and difficult to manage due to the sheer volume of devices needing inspection.
Innovation Solution
An apparatus and method that determines the states of circuit breakers and disconnecting switches using data from a remote control system, assigns weights based on consistency, and generates alarms when accumulated weights exceed a threshold, ensuring stable and efficient error correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inconsistency inspection is performed on all circuit breakers and disconnecting switches, then error detection reliability is improved, but system complexity and operational burden increase significantly
Solution Approach 1:
The patent segments the inspection process by dividing circuit breakers and disconnecting switches into different stations, and further segments the inspection methodology by creating multiple inspection tables (first inspection table for normal operations, second inspection table for abnormal operations). This segmentation allows the system to handle large numbers of devices through structured, manageable units rather than treating all devices uniformly, thereby improving reliability without overwhelming system complexity
Solution Approach 2:
The patent performs preliminary actions by pre-defining inspection tables with expected normal and abnormal operational states before actual inspection occurs. The system pre-establishes what constitutes consistent versus inconsistent states for various operational scenarios, allowing automated comparison during runtime. This preliminary structuring enables reliable error detection without requiring complex real-time analysis of all possible states
2Ease of operation
If arbitrary selection of circuit breakers and disconnecting switches is used for inspection, then operational burden is reduced, but error detection reliability deteriorates
Solution Approach 1:
The patent creates a universal inspection framework that handles both normal and abnormal operational states through a single integrated system. The same inspection mechanism universally applies to all circuit breakers and disconnecting switches across all stations, regardless of their specific operational context. This multi-functional approach allows the system to maintain high reliability through comprehensive coverage while keeping operations simple through standardized procedures
Solution Approach 2:
The patent implements feedback mechanisms where the inspection system continuously compares actual operational states against expected states from the inspection tables. When inconsistencies are detected, the system generates alerts that feed back to operators for correction. This closed-loop feedback ensures high reliability by systematically identifying errors while maintaining ease of operation through automated monitoring rather than manual inspection of all devices
3Measurement precision
If comprehensive inspection of all devices is performed, then data accuracy is improved, but time consumption and productivity loss increase
Solution Approach 1:
The patent implements periodic action by structuring inspections around discrete operational events rather than continuous monitoring. The system performs inspections at specific periods: when operational commands are issued, when state changes occur, or when alerts are triggered. This event-driven periodic inspection maintains high data accuracy by checking at critical moments while minimizing time loss by avoiding constant continuous inspection of all devices
Solution Approach 2:
The patent applies partial action by focusing inspection resources on detecting inconsistencies rather than verifying every single operational parameter of every device. The inspection tables define specific critical states to check (normal vs. abnormal operations) rather than examining all possible parameters. This selective partial inspection maintains sufficient data accuracy for system safety while dramatically reducing the time and computational resources required compared to exhaustive inspection

AI summary
Disclosed are an apparatus for correcting an error of acquired data and a method thereof. The method includes determining whether states of at least one circuit breaker and at least one disconnecting switch included in at least one station are consistent with each other based on data received from at least one remote control apparatus including the at least one station; assigning a weight to a corresponding circuit breaker and a corresponding disconnecting switch and the station including the corresponding circuit breaker and the corresponding disconnecting switch when the determination result represents that the states of the circuit breaker and the disconnecting switch are inconsistent with each other; creating alarm information notifying a malfunction of the corresponding circuit breaker and the corresponding disconnecting switch when an accumulated weight value is equal to or greater than a preset reference weight value; and outputting an alarm corresponding to the alarm information.
