Strategic Importance
“…it's clear that the power grid needs an overhaul. It needs to be
modernized. As we go into an exciting new period of American
history, we want the most modern electricity grid for our people… we need more investment; we need
research and development…”President BushSeptember 2003
“When the lights go out, modern life as we know it grinds to a sudden halt.
Transportation is interrupted, communications fail, water systems
shut down, factory work is disrupted, food spoils, businesses lose money, and people are inconvenienced and
even endangered. ”
Secretary AbrahamApril 2004

Retriever Study Mode
• Create a power flow case from real-time state estimator data
• Phasor retrieval from state estimator or PMU
• Applications– operator training for emergency operation or post-
mortem analysis– Contingency, ATC, voltage stability analysis based on
real system conditions

Real-Time Phasor Visualization 34June 24, 2005
Retriever Connection:Secure Shell
• By setting up a VPN tunnel in another application , you can retrieve data via FTP or HTTP encrypted.
• Involves mapping requests against a particular local port to a port on a remote VPN server.

HTTP
Real-Time Phasor Visualization 35June 24, 2005
Retriever Connection: DatAWare
• Dataware is a data archiving tool written by TVA Nuclear Operations
• Provides both a client-side and a server-side API• PowerWorld has written a server-side Dataware-Retriever bridge
– Periodically queries the server for new data– Publishes the newly retrieved data to a flat file– Retriever then downloads this flat file using ftp, http, or direct disk
access
Real-Time Phasor Visualization 36June 24, 2005
Retriever Connection: OPC
• Retriever can download data from an OPC server
• Data is cached locally as it is generated at the OPC server
• Displays are refreshed at a user-specified interval
Real-Time Phasor Visualization 37June 24, 2005
Summary
• Retriever brings all the visualization techniques of PowerWorld to the on-line environment
• Advantages– Flexibility in data and display format
– Ability to communicate complex data and trends quickly, in a manner that is easily understood by engineers and management
– Visualization platform developed over several years and guided by hundreds of customers and research
