OMT - Overview

• Customer driven.

• Customer outages are georeferenced.

• Logically connected network.

• Outages are assessed and prioritized.

Geographically related

Electrically related

Prioritized by number and type of customers affected

OMT – Problems

• Relies on customers to report outages.

May or may not report outage.

Customer observations may be unreliable.

• Reactive versus proactive.

• Labor and time intensive analysis.

• Delay in analysis causes restoration delays.

• Verification of outage restoration.

AMI – Overview

• Automated Metering Infrastructure (AMI).

Two-way Automatic Communication System (TWACS).

• Remote meter reading.

• Allows for the “ping” of the meter.

Implementation - Technology

• Visual Studio .NET and C#

• Component-based Scalable Logical Architecture (CSLA .NET) by Rockford Lhotka - www.lhotka.net

• ArcObjects used to create custom trace routines to trace the GIS logical network.

• Service Oriented Architecture (SOA) - Command Request Framework

• TWACS hijacking
