PowerWorld Corporation | Retriever and NASPI

PowerWorld Corporation has been participating in the North American SynchroPhasor Initiative (NASPI, formerly the Eastern Interconnect Phasors Project) to develop specialized tools and features for wide-area phasor monitoring in PowerWorld Retriever.


	PowerWorld Retriever is the weather map of the control room, providing an instant overview of wide-area system health and helping operators discern what is most important during system emergencies.

PowerWorld Retriever is ideal for wide-area monitoring and visualization:

Simultaneous visualization of related quantities such as voltage magnitude, phase angle, and angle differences across transmission paths;

Flexible specification of system reference angle;

Connection to TVA's DatAWare host, allowing eastern interconnect utilities and RTOs to view the same displays at the same time

Tolerance of communication faults to recognize temporary dropouts of readings

Automatic topology processing to create a power flow case from a bus-breaker system model

Gauges show voltage magnitude; contouring shows phase angle, with numeric readings for angle differences across path and dynamic emphasis showing alarm condition (in pink)
