The PRISM Real-time Outage Management System (OMS) doesn’t just minimize network outages; it dramatically improves the network by accessing and updating the same data as SCADA, real-time automation and real-time analysis. These applications are presented as part of a unified operator interface, reducing reaction time, simplifying training, and optimizing data flow. It’s unique among comprehensive outage solutions is the industry’s first truly integrated OMS for the Smart Grid.
Minimal OMS Maintenance Costs
PRISM Real-time OMS solves the traditional database maintenance and synchronization problems inherent with traditional OMS systems by using the same model and the same data as SCADA and integrated DMS applications.
The electrical network database and model is maintained using the utility’s existing GIS as the source database editor.
Maximum Accuracy
Since PRISM employs a single network model, and therefore shares the same topology among OMS and all other DMS applications, PRISM Real-Time OMS is updated immediately when changes occur.
The topology is always up-to-date. This means accurate fault predictions and crew dispatch.
Maximum Performance
Most outage management systems are based on GIS platforms whose graphics and relational database were not designed for real-time performance.
As a result, these systems often suffer serious performance problems during emergencies and other periods of high activity. PRISM Outage Management System is built to meet the performance demands of a SCADA/EMS/DMS — both in its graphics and real-time data processing capability.
Reduced Customer Calls and Outage Time
PRISM Real-Time OMS includes optional feeder automation applications that automatically restore service to restorable sections of the feeder within seconds.
This not only minimizes calls, but benefits non-automated areas of the distribution network, since crews can be dispatched to where they are truly needed. Since the topology changes that result from automatic reconfiguration are known immediately by the OMS, operators know almost instantaneously that power has been restored.
Map View
The distribution and outage management systems share a common operator interface.
The same data model supports schematic and geographic network views. The integration of data and graphics, along with enhanced features, enhances call center and dispatcher operations.
Call Management
The PRISM OMS Customer tab organizes the information with a customer focus.
The customer information is organized and displayed both graphically and in tabular form by area in order to focus on critical accounts. OMS provides the following features:
Ticket Generation
PRISM Outage Management System provides a Ticket Management system that summarizes all of the ticket information and is primarily used by the Operator / Dispatcher.
Ticket Management is designed to assist the Operator Dispatcher to analyze the location of any ticket (prediction or confirmed outage) and to monitor the repair progress. The Ticket Summary display provides an itemized summary of all Tickets on the system in whole or by area.
Following calls or outage reports that are not telemetry-driven, a prediction of a device failure or outage location is made. The system automatically generates an Incident Ticket. Trouble Ticket Management manages outages as either Incident (predicted) Tickets or as Outage (confirmed) Tickets. A Ticket is automatically assigned to an area.
A roll-up numeric of the total number of Tickets for each level (# total) is displayed with each group. When a Ticket is generated the system updates the Trouble Ticket Summary display identifying the predicted outage devices and other relevant data for comparison and monitoring purposes. The Trouble Ticket Summary display shows a summary utilizing a single line per ticket.
Since PRISM Outage Management System incorporates SCADA telemetry, the system will behave differently on automated circuits than on non-automated circuits. The system will not generate a predicted incident against a device which the telemetry shows to be closed. The prediction algorithm will look further upstream to the next non-telemetered device. Any device which operates under SCADA control as a commanded change of state, the system will generate an outage ticket which does not have to be confirmed by a crew. If the automated switch operated automatically based on a fault condition (un-commanded), then the system will predict an incident downstream of the open switch.
Conversely if an open switch closes automatically, or under SCADA control, the system will close the outage ticket and commence with the call back process to inform the affected customers. The SCADA generated tickets are logged as SCADA generated so as to differentiate them from tickets generated manually or by the prediction algorithm.
Outage Prediction
PRISM Outage Management System uses entered customer call data as well as external event information from available system data sources including SCADA, AMI, IVR, etc. to perform an outage analysis.
The algorithm uses the real-time network topology-tracing algorithm with rules that provide automatic faulted device prediction in order to minimize the prediction accuracy resulting in the timely restoration of all customer outages. The system supports a number of user configured tuning parameters and features that adjust the behavior of the prediction analysis in order to meet the different operational preferences of each utility.
Crew Management
Crew Management provides an organized and efficient way to manage the correlation of crews to Work Orders or Tickets.
The Crew Management user interface is designed to enhance the dispatcher or supervisor’s situational awareness of the progress of outage restoration or work resolution. As such, the Crew Management tab enables the Operator / Dispatcher to create crews, monitor crews and assign crews to jobs. The dispatcher is able to monitor the crew workload and the crew’s progress. If improved crew workload balancing can be accomplished or if changes in the personnel or resources are required in order to accomplish timely restoration, the dispatcher can monitor and make these changes from the Crew tab.
Work Orders
PRISM Outage Management System provides the capability to manage crews and activity related to daily work orders.
Outages represent the emergency work. Work Orders are specifically non-outage related jobs. Since the majority of the utility work is not related to outages or emergencies but for capital or maintenance work, the Work Order Management subsystem in OMS is used to schedule the work for independent creation, tracking and management of each job. The Work Orders are often defined outside of OMS (in an IT Work Management System) or those jobs that are manually entered into OMS.
Work orders may be linked to Tickets if the work order is related to the outage. In this case even if the outage is closed following complete restoration of service, the work order may remain open until all repairs are completed.
Similar Summary screens and Detail screens are used to monitor and to manage Work Orders as those that are used to manage Tickets.
Reporting
The system offers both real-time dashboard summaries of the system as well as detailed tabular and graphic reports supporting drill-down and query capability.
A set of standard reports are provided which cover Crew, Ticket, Outage, Call, outage codes, call codes, failure codes, calculations, area reports, device operation, etc. The user is able to create custom reports using drag and drop from the data model.
PRISM Outage Management System automatically calculates the IEEE 1366 performance indices such as SAIDI, CAIDI, SAIFI based on the logged events, times and degree of restoration for display and reporting.
