Outage Management System

The Outage Management System (OMS) leverages the smart meters’ internal battery and remote communications, to receive a “last gasp” outage alert, during the absence of external power. The OMS receives the load profile channels for the two minutes prior to the outage in order to analyze and diagnose the probable cause of outage, such as loss of phase, overload, or drop in frequency. This will provide important data in real-time to quickly detect a potential power outage event of transformer, feeders and substations, scoping the size and location of the outage and pinpointing affected service points and for both predictive and post-incident analysis to identify likely upstream incident devices.

The OMS automatically monitors levels of service by outages, and can provide reports to relevant stakeholders (utility personnel, consumers, media and regulators) on the state of the restoration process and automatically identifying equipment and customers affected by outages. The OMS can also generate intuitive reporting, introducing reporting data visually in chart format of outage information, as well as exporting this data for further analysis. All events are forwarded to the utility team in charge by SMS/Email.

This AMI based OMS provides accurate information on the behavior of the network in near real time eliminating costly and time consuming network analysis and predictions, field validation, etc. By using the OMS, dispatchers could easily view the network behavior in near real time and validate outages by simply pinging the smart meters in order to validate and identify the cause of the outage without having to send truck rolls to visually validate possible outages points.

During restoration, the OMS will verify the effectiveness and completeness of the restoration activity. As it receives “power-up notifications” from restored smart metering end-points, the OMS can ping the other meters associated with that feeder or transformer to validate that all endpoints have been restored or identify potential nested outages before crews leave the area.

The system will send an alert notifications to the Area Managers responsible for outages, and send another notification when the power is restored, and the event is closed. The OMS will manage the status of crew assignments to the outages, and monitoring the state of the restoration activities. When the maintenance teams are on-site, the OMS can inform the maintenance team that a specific switchgear of a particular feeder is disconnected, and validate that the power is off to safely and efficiently manage emergency-related work.

The flexible reporting tool with data filtering functionality, allowing application users to perform ID search by equipment ID or customer ID, increases efficiency of outage processing under system control with a high-degree of user functionality and ease of use.
