Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power system operators face difficulties in selecting an appropriate operation candidate within a few seconds during system events due to numerous operation candidates, even with existing techniques like stabilization control based on control target information from a control table.
Innovation Solution
An operation support device with a similarity determination unit and a control candidate table update unit that compares actual measured data with simulated data to determine the similarity and update the control candidate table, presenting a more appropriate control candidate to the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operators manually evaluate multiple operation candidates during system events, then they can select appropriate control actions, but the selection time exceeds the required few seconds due to the large number of candidates
Solution Approach 1:
The patent creates simulated data copies representing hypothetical system states after executing each control candidate. Instead of manually evaluating all candidates, the system generates simulated copies of system behavior for each candidate and compares them against actual measured data. This copying approach enables automated evaluation of multiple candidates within seconds while maintaining selection accuracy.
Solution Approach 2:
The patent performs preliminary simulation of system responses to all control candidates before the operator needs to make a decision. By pre-computing simulated data for each candidate and preparing comparison results, the system eliminates time-consuming manual evaluation during actual events, enabling selection within the required few seconds.
2Adaptability or versatility
If the control candidate table includes all possible operation candidates, then comprehensive control options are available, but the operator cannot appropriately select from the large number of candidates within a few seconds
Solution Approach 1:
The patent implements automated feedback by comparing actual measured data with simulated data for each control candidate. The system evaluates similarity between measured and simulated responses, automatically ranking candidates based on how well their simulated outcomes match actual system behavior. This feedback mechanism transforms the overwhelming selection task into an automated evaluation process that maintains comprehensive options while dramatically improving selection ease.
Solution Approach 2:
The patent replaces the mechanical process of manual operator evaluation with an automated computational system. Instead of operators manually assessing each candidate's suitability, the system automatically computes similarity metrics between measured and simulated data, substituting human cognitive effort with computational algorithms that can process all candidates within seconds.
3Extent of automation
If stabilization control is performed based on control target information from a control table, then control automation is improved, but appropriate control candidate selection remains difficult during system events
Solution Approach 1:
The patent introduces dynamic evaluation of control candidates by continuously comparing actual measured data with simulated data for each candidate. Instead of relying on static control tables, the system dynamically assesses which candidates produce simulated responses most similar to actual system behavior. This dynamic approach maintains automation while improving the reliability of candidate selection by adapting to real-time system conditions.
