Reliability Improvements in Distribution Systems

This analysis covers all of the SGIG projects that deployed smart systems on electric distribution circuits for automated feeder switching, equipment health monitoring, and AMI-connected outage notification through smart switches, line monitors, reclosers, and controls to limit the scope, frequency and duration of power outages.

The key analysis question concerned how, and to what extent, smart grid technologies improved distribution system reliability by reducing outage duration and the number of customers affected. Analysis objectives included:

  • Determining the reduction in outage duration and scope within distribution systems through the application of technologies used to identify outages and reconfigure faulted segments of distribution feeders.
  • Determining the effect on reliability from equipment health monitoring technologies.
  • Determining technology configurations that are most important for delivering measurable results.
