System Highlights

RTDMS is a phasor based monitoring application that offers real-time wide-area visibility, as well as monitoring and alarming functions on high resolution sub-second phasor data.

The system supports a centralized RTDMS Server performing key data management functions such as data reading, cleansing, computing and archiving.

Multiple RTDMS Client applications simultaneously access the information from the central RTDMS Server and, through various geographic and graphic displays, provide operators and dispatchers both real-time information and alarms.

Real Time information and Visualizations

	Situational Awareness Screen (Summary Dashboard) Provides an integrated information in a common centralized display Provides real time situational information at a glance
Voltage Magnitude and Relative Angles comprehensive profile of voltage angles and magnitudes identify the high and low voltage regions within the grid monitor angles relative to a specific reference
	Angle Differences across Identified Transmission Flowgates provides a birds-eye view of the sources and sinks of power monitor phase angle differences across key flowgates
System and Local Frequencies assess system coherency and dynamic stress under normal operating conditions identify approximate point of acceleration or deceleration (loss or load or generation)
	Real and Reactive Power Flows Across Monitored Lines monitor actual MW and MVAR flows at key flowgates track flows with respect to predefined thresholds
