Built on the GRID-3PTM Platform, Phasor Real-Time Dynamics Monitoring System (RTDMS) provides: Real-time Situational Awareness over wide-area or the entire interconnection Reliability Monitoring of key metrics to assure reliable, efficient, and secure grid operations Compliance Monitoring relative to key metrics, thresholds and standards Performance Assessment of key metrics and data quality

Information made available through Phasor-RTDMS
Wide Area View Provides a birds'-eye wide-area view of key monitored metrics across the grid within geographic and dashboard type summary displays.		Monitored Key Metrics System Frequencies, Voltages, Phase Angles, Angle Differences between major sources and sinks, MW and MVAR flows across key flowgates
Violation of Thresholds Real-time visual (color coded) and textual alarming upon violation of pre-defined thresholds and rate-of-change.		Reporting Ability to generate reports on the long-term trends of key metrics, PMU or PDC performance, and historical records of events and alarms.
Analytics and Forensics Ability to analyze captured event files for post-disturbance assessment.		Identification of System Anomalies Color coded visuals, histograms and statistical limits (“soft” limits) to detect system anomalies.

From X-Ray to MRI:

• High resolution, phasor data is sampled 30 to 60 times per second

• The wide area data is synchronized by GPS time stamping

• This data is processed real-time using advanced algorithms and modeling

• The information is presented to Operators and Reliability Coordinators visually

• The advanced visualization is designed for performance monitoring, rapid response
  and analysis

• The system also has threshold and event based alarm triggering, that automatically
  record violation events

• This high resolution, MRI quality information is archived for reporting, analytics
  and advanced forensics.

Phasor-RTDMS^TM has been developed by Electric Power Group, a member of CERTS,  with sponsorship
of Department of Energy’s Office of Electricity Delivery and Energy Reliability (OEDER) and California Energy Commission Transmission Research Program.

Phasor-RTDMS has been developed for use in the Western Interconnection by CAISO dispatchers and
 reliability coordinators and participating utilities. 

Phasor-RTDMS is also in use by the Eastern Interconnection Phasor Project participants.
