Alstom has delivered a new Outage Management System (OMS) and Distribution Management System (DMS) upgrade to Alabama Power, a subsidiary of Atlanta-based Southern Company, completing delivery of Alstom’s full Integrated Distribution Management System (IDMS).
The Distribution SCADA and DMS modules of the IDMS delivered previously have been efficiently directing the flow of electricity to Alabama Power’s 1.4 million customers. The addition of the OMS ensures more efficient and faster decision making especially during large scale outage restoration efforts, ultimately improving service to Alabama Power’s customers.
In preparation for system acceptance, the new OMS was tested using Alstom’s integrated Distribution Operations Training Simulator (DOTS). Performance and scalability testing were simulated using DOTS generated inputs from SCADA, AMI, customer calls and based on some of the largest storms that may impact the Alabama Power’s service territory — with more than one million customers out, over 160 concurrent users of IDMS, 60 percent AMI outage response, loss of the entire SCADA communications infrastructure, and about 2,000 distribution circuits with active outages.
Built for high availability and performance during major events, as well as routine maintenance outages, Alstom’s OMS is designed to handle over 200,000 trouble calls per hour.
The new OMS, which is based on Alstom Grid’s e-terradistribution platform, provides Alabama Power’s distribution grid operators more accurate information and enhanced overall visibility to better manage unscheduled and planned network outages. Based on a Service Oriented Architecture, the new OMS includes web service APIs for seamless integration with Alabama Power’s enterprise systems, through the Enterprise Service Bus to the Geographic Information System, Customer Information System, Advanced Metering Infrastructure, Mobile Workforce Management, and Automatic Vehicle Location.
The new OMS also captures and integrates all available data to automatically calculate performance indices, like System Average Interruption Duration Index (SAIDI) and Customer Average Interruption Duration Index (CAIDI), ensuring accuracy and confidence in overall outage reporting metrics.
