D4: Distribution Operator Locates Outage Using AMI Data and Restores Service

AMI offers excellent opportunities for enhancing a utility’s ability to identify and rectify outages. Currently, utilities are constrained in their response to outages by the sensors, or information available to them. SCADA systems typically extend only to the substation. Remote Fault Indicators (RFIs) provide insight further into the network, but are limited in number. AMI is the only system that extends (by definition) to the extreme ends of the utility network. AMI systems can sense every line segment and transformer on the system. This capability can be used to verify not only pinpoint outages but power restoration as well, enabling utilities to proactively identify customers who have not yet been restored. Outages reported by other systems (SCADA, DCMS or even customers) can be explored to determine the extent of the outage. This capability can reduce labor and truck roll costs by better identifying the cause of outages and sending the proper people and equipment. Further truck rolls can be eliminated by verifying customer reported outages are not customer equipment issues.
