Voltage Rating Validator for Advanced Metering Infrastructure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to accurately validate voltage meter ratings in electrical power distribution systems, leading to potential damage from incorrect voltage readings, as they cannot effectively process Advanced Metering Infrastructure (AMI) measurements to detect varying voltages at end-user premises.
Innovation Solution
A system and method that filter voltage measurements to determine a commonly recurring voltage, compare it to candidate ratings, calculate differences, and select a measured voltage rating, while accessing and updating stored ratings to maintain the distribution system's accuracy and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If voltage measurements are collected from AMI devices at end-user premises, then voltage information can be obtained without sending a technician, but existing solutions cannot validate meter voltage ratings from these measurements
Solution Approach 1:
The system collects voltage measurements from AMI devices and uses this feedback to validate and update meter voltage ratings in the central system. The measured voltages are compared against candidate ratings to determine the correct rating, creating a closed-loop validation process that continuously improves accuracy
Solution Approach 2:
The system enables automated self-validation of meter ratings by processing AMI measurements through filtering, statistical analysis, and comparison algorithms. This eliminates the need for manual technician visits while achieving accurate rating validation through automated data processing
2Measurement precision
If voltage measurements are taken at each end point to detect varying voltages, then accurate local voltage detection is achieved, but the complexity of processing and validating these measurements increases
Solution Approach 1:
The validation process is segmented into distinct stages: data collection from AMI devices, filtering to remove outliers, statistical analysis to determine commonly recurring voltages, and comparison against candidate ratings. This segmentation simplifies the overall complexity by breaking down the validation process into manageable, automated steps
Solution Approach 2:
The system introduces a central processing system that acts as an intermediary between AMI devices and the meter inventory database. This intermediary automatically processes measurements, performs validation logic, and updates ratings, reducing the complexity burden from individual endpoints
3Reliability
If incorrect meter voltage ratings are stored in the central system, then erroneous actions may be taken that could damage user equipment, but manual verification of each meter rating is impractical
Solution Approach 1:
The system performs automated self-verification of meter ratings by comparing AMI measurements against candidate ratings and updating the central database accordingly. This eliminates manual verification needs while maintaining high reliability through continuous automated validation
Solution Approach 2:
The system uses feedback from actual voltage measurements to continuously validate and correct meter ratings in the central system. This closed-loop approach ensures reliability by preventing erroneous ratings from causing damage, while maintaining high productivity through automated processing

AI summary
Systems and methods for determining a voltage meter rating for a utility meter connected to a distribution system via one or more distribution lines. The system accesses voltage measurements provided by a meter that represent a voltage at different time intervals. The system filters the voltage measurements to remove any voltage measurements that fall outside a voltage range for the distribution line. The system further determines a measured voltage rating from a set of candidate voltage ratings for the meter. The system compares a stored voltage rating for the meter and the measured voltage rating to determine a confidence level for the measured voltage rating. When the confidence level for measured voltage rating exceeds a confidence threshold, the system uses the measured voltage rating to maintain the distribution system.
