Visualization Challenges

• Situation Awareness for large geographical area• Tracking of 1300 generators: unit status, MW and

MVAR output, unit reserves• Tracking system voltages throughout 13 state territory• Viewing transmission zone overviews for a large grid• Keeping track of wind generation output and forecast• Track MW transfers into PJM and across the

transmission system• Consistent displays in each control room

IEP Real-Time UI

Single UI Shows Operators, Correlated Data, Priority, and Operating Procedures in single interface.Supervisors can see which Operators are actively working or monitoring events. The application also shows updates to events after they have triggered.

IEP Rule Builder Form• Simple, form-driven UI

allows Operations users to create and update rules themselves.

• All approval workflow, rule activation/deactivation is controlled by Operations Staff. No programming knowledge is needed.

• Training on the rule builder is less than 1 hour.

• Rich-Text Alarm action box allows for charts, external links, and data formatting to provide the Operator with the data he needs to work the event at hand.
