Wide-Area Network Monitoring

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

	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.
	openPDC Data Stream in PowerWorld Retriever (wmv) Real-time contour at more than 30 frames per second, showing frequency from the Grid Protection Alliance openPDC Test Data Stream. The feature uses OpenGL graphics rendering and is in beta development. 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
