Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing event reports generated by intelligent electronic devices (IEDs) in electric power systems often include a significant amount of irrelevant information, making it difficult to access valuable data that could improve the safety, reliability, and efficiency of the power system.
Innovation Solution
The development of adaptive protective relay event reports that can be customized to specific applications, allowing for the tailoring of information included in the reports to focus on the most relevant data, thereby improving resource utilization and data accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional event reports include all available data from intelligent electronic devices, then the completeness of information is improved, but the difficulty of accessing valuable data increases due to the significant amount of irrelevant information
Solution Approach 1:
The patent segments event report data into multiple priority levels (first priority, second priority, third priority) based on relevance to system safety and operation. This segmentation allows the report to maintain completeness by including all data while improving accessibility by organizing it into hierarchical groups where critical information is presented first, enabling operators to quickly access valuable data without being overwhelmed by irrelevant information.
2Reliability
If event reports include comprehensive data from multiple sources, then the reliability of analysis is improved, but the time required for analysis increases
Solution Approach 1:
The patent applies preliminary action by pre-categorizing and prioritizing event data before it needs to be analyzed. The system automatically classifies data into priority levels based on predetermined criteria related to system safety and operation during normal conditions. This pre-processing ensures that when analysis is needed, the most relevant information is already organized and accessible, maintaining reliability through comprehensive data while significantly reducing analysis time.
3Productivity
If adaptive protective relay event reports are customized to specific applications, then the efficiency of resource utilization is improved, but the complexity of report configuration increases
Solution Approach 1:
The patent implements parameter changes by allowing the prioritization criteria to be adjusted based on different system operating conditions and applications. The system can modify which parameters are used for data classification depending on whether the system is in normal operation, emergency mode, or maintenance mode. This enables customization for specific applications and optimizes resource utilization while managing configuration complexity through conditional parameter adjustment rather than complete reconfiguration.
Data Source
AI summary
The present application relates to generating adaptive protective relay event reports. In one embodiment, a system comprises a power system response subsystem to monitor electrical parameters in an electric power system and to receive a trigger signal from a trigger source based on identification of an event in an electric power system. An adaptive event report subsystem is configured to generate an adaptive report depending on the trigger related to the event and based on a pre-trigger start, a duration, and a sampling rate. The adaptive event report comprises at least one electrical parameter related to the event beginning at a time established by the pre-trigger start, covering an interval established by the duration, and recorded at the sampling rate.
