Process Bus Transformer Settings for Measurement Error Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current process bus systems face measurement errors due to missing or unidentified transformer settings, leading to maloperation of protection functions and requiring manual effort and expertise to identify compatibility issues.
Innovation Solution
A method and engineering tool that receive and parse files from a system configurator tool to identify transformer settings for process bus devices, fetch information from installation data when settings are missing, mark missing values for visual notification, and publish identified settings to a remote database to reduce measurement errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual identification of transformer settings is performed by technicians, then measurement errors can be identified, but the process requires significant manual effort and technical expertise
Solution Approach 1:
The system performs self-diagnosis by automatically comparing device configuration files (ICD/IID) with expected settings, identifying measurement errors without requiring technician intervention for the identification process itself
Solution Approach 2:
An automated analysis tool acts as an intermediary between the device configuration files and the technician, performing the complex comparison and identification work, then presenting results to the technician for verification
2Adaptability or versatility
If ICD/IID files from different vendors are used without crucial settings, then device compatibility is maintained, but measurement errors occur due to missing transformer settings
Solution Approach 1:
The system performs preliminary analysis of ICD/IID files during the configuration phase to identify missing transformer settings before the device is deployed, allowing settings to be added or corrected in advance
Solution Approach 2:
The system provides feedback to technicians by highlighting specific missing settings (such as ScndTmms, sample rate, MaxDI) in the configuration files, enabling targeted corrections to achieve both compatibility and measurement accuracy
3Productivity
If automated identification of transformer settings is implemented, then manual effort is reduced, but system complexity increases
Solution Approach 1:
The system uses a universal analysis approach that works with ICD files from any vendor by comparing against a standardized set of expected transformer settings, making the tool broadly applicable without requiring vendor-specific customization
Solution Approach 2:
The system creates a simplified representation of the device configuration by parsing ICD/IID files and extracting relevant settings information, working with this copied data structure rather than the original complex files directly
Data Source
AI summary
A method and device for reducing measurement error/s is provided. The method receives a file by an engineering tool from a system configurator tool and parses the file to identify a value associated with a transformer setting for a process bus device. The method fetches information from installation data to identify the value when the value is not identified in the file and stores the value in the engineering tool when the value is identified in the file or in the information. The method marks the value as a missing value to visually notify a technician when the value is not identified in the information or the file. The method publishes the value at a remote database for process bus subscriber device/s.
