Integration of OMS with these systems results in improved workflow efficiency and enhanced customer service. OMS systems have also become more integrated with other operational systems such as Geographic Information Systems (GIS), Customer Information Systems (CIS), Work Management Systems (WMS), Mobile Workforce Management (MWM), SCADA, and AMI.

Interfaces to Interactive Voice Response systems (IVR) permit trouble call entry into an OMS without call-taker interaction and also permits the OMS to provide outage status information to customers and provide restoration verification call-backs to customers who request them. Outage prediction вЂ“ the process of analyzing outage events such as trouble calls, AMI outage notifications, and SCADA-reported status changes вЂ“ has improved. In recent years, OMS has become more automated. Connectivity maps of the distribution system assist operators with outage management, including partial restorations and detection of nested outages. OMS typically includes functions such as trouble-call handling, outage analysis and prediction, crew management, and reliability reporting.

Modern computer-based OMS, utilizing connectivity models and graphical user interfaces, has been in operation for some time now. Recent trends in SCADA include providing increased situational awareness through improved GUIs and presentation of data and information intelligent alarm processing the utilization of thin clients and web-based clients improved integration with other engineering and business systems and enhanced security features. Installed at a centralized location, such as the utility control center, are front-end data acquisition equipment, SCADA software, operator GUI (graphical user interface), engineering applications that act on the data, historian software, and other components. RTUs (Remote Terminal Units) are used to collect analog and status telemetry data from field devices, as well as communicate control commands to the field devices. SCADA systems are globally accepted as a means of real-time monitoring and control of electric power systems, particularly generation and transmission systems. Finally, a proposed architecture for an integrated distribution operations center is presented. Next, the integration of SCADA with DMS/OMS is discussed, including the functionality of the integration and the resulting benefits. Considering that both OMS and DMS require a connectivity model of the distribution system, the benefits of integrating OMS and DMS are presented.

This article first reviews SCADA, OMS, and DMS systems. While a DMS can include and improve the traditional outage management functions, a DMS also typically includes applications that assist in the improved operation of the electric distribution system, as well as functionality for improving planned work on the system. The implementation of DMS functionality is a relatively recent trend. Modern OMS, utilizing GIS-based connectivity models, is now well established and a key component of many organizationsвЂ™ outage management business processes. SCADA, which has long been prevalent throughout transmission systems, is finding increased applications on distribution systems. Print Many electric distribution organizations are presently evaluating their approach to integrating three key operational systems вЂ“ SCADA (Supervisory Control and Data Acquisition), OMS (Outage Management System) and DMS (Distribution Management System).
