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.
Synchrophasor Visualization in PowerWorld
Retriever (avi)
Contouring shows phase angle, with numeric
readings for angle differences across path and
flashing red for alarm condition.
Data are fictitious and for illustration only.
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 and state estimator
Gauges show voltage magnitude; contouring shows phase angle, with numeric readings
for angle differences across path and dynamic emphasis showing alarm condition (in pink)
