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-RTDMSTM 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. |
