Introduction

Grid Operations is a program for managing analytics related to the electric distribution system. Grid Operations is part of Grid Reliability in the Intelligent Edge Operating System (IEOS). Its use cases include:

• DI Active Transformer Load Monitoring

  • Identifies transformer load issues such as high load, reverse load, poor power factor, or unbalance load based on data from Distributed Intelligence (DI) agents on end-point meters under the transformer

• DI Active Transformer Voltage Monitoring

  • Identifies over and under voltage issues based on data from Distributed Intelligence (DI) agents on end-point meters under the transformer

• EV Charging

  • Identifies service points whose electric usage pattern indicates high likelihood that an electric vehicle is being charged there

• Exceptions / Connection data issues

  • Identifies service points not connected to a transformer, transformers with no connected service points, and transformers not connected to a feeder according to the data supplied by the utility

• Exceptions / Service Type Mismatch

  • Identifies the electric service type based on phase data provided by a Power Quality data feed from AMM

• Solar Service Points

  • Identifies service points whose recent received electric pattern indicates that there is a high likelihood that solar panels are installed on the premise

• Transformer Loading (Loss of Life)

  • Identify transformers whose IEEE loss of life calculations indicate approaching end of life and/or rapid loss of life

• Transformer Loss Balance

  • Identifies transformers with high calculated loss, comparing usage metered at the transformer to the sum of the usage metered at downstream meters

• Transformer Phase Balancing

  • Identifies transformers with consistent, high differences in current levels across the three phases

• Transformer Over/Under Voltage (End Pts)

  • Identifies transformers whose underlying service points are frequently over voltage or under voltage

• Transformer Over/Under Voltage (Trans Mtr)

  • Identifies transformers whose transformer meter's phase voltage readings are frequently above or below the desired threshold relative to nominal (default +/-5%)

• Over-/Under-Utilized CTs

  • Identifies transformer-rated service points whose interval readings indicate that the service's current transformer may be sized too large or too small for the usage at the service point

• Power Factor Low at Peak

  • Identifies all service points that have a positive KVA correction value for the most recent complete month
