Utilizing Real-Time Digital Simulation (RTDS) Technology

INDEPENDENT RTDS TESTING LABORATORY FOR DEVICE/APPLICATION

PERFORMANCE EVALUATION

RTDS is a real-time power system simulation platform for precise modeling and analysis of transient phenomena, utilizing

simulation time close to the time frame of actual events. It was primarily developed and utilized for hardware-in-the-loop

(HIL) testing of protective relays, digital controllers and process control devices for performance evaluation and pre-

commissioning testing under real-world conditions. RTDS testing is also commonly used for prototype development and/or

finalizing a new application design involving several digital control, protection and measurement devices.

RTDS testing normally involves sequence of event analysis by developing

realistic test scenarios under which the application performance needs to be

evaluated. In an RTDS test setup, simulated power system quantities (e.g.

voltages and currents at secondary levels), status signals and control

commands (e.g. circuit breaker on/off positions and tap-changers status) are

exchanged with the control or protection devices in real time through several

analog and digital interface cards with high precision.

Simultaneously, the processed signals and/or control commands (e.g. trip

signals from protective relays and gating control signals for power electronic

apparatus), representing the reaction of the devices under the test to the

simulated phenomena are fed back to the real time simulator. The feedback

signals and control commands from the devices are used to adjust the power system topology and change any applicable set

points as typically performed by system operators or dispatch centers.

Utilities can benefit significantly by utilizing the computing power that RTDS provides. Most utilities do not own Real-Time

Digital Simulators because these are expensive testing tools. In addition, utilities find it hard to maintain a dedicated staff

proficient in running analysis/testing using RTDS. With this in mind, Quanta Technology has established an RTDS lab in partnership with North Carolina State University in Raleigh, NC. The lab currently performs testing/analysis for several utilities.

The precise representation of complex power system transient phenomena (faults, frequency oscillations, voltage collapse)

and real-time interactions with the actual control and protective devices (rather than modeling them) are the salient features of

RTDS testing. Practically unlimited number of test cases and study scenarios can be generated and used to evaluate device

performance and operation under system normal and contingency (N-1/N-2) conditions.

PERFORMANCE EVALUATION

Some of the questions that RTDS can answer for you:

Is the logic for the RAS/SPS system sound and sturdy

enough?

How will the PMU perform within a network? Is there a need

to do close loop testing and verify appropriate performance

of the PDCs?

Will the PV controls work appropriately when integrated into

an existing system?

Can actual relay hardware be used to verify the

dependability and security of the relays in a critical

transmission line?

After a thorough review of the system settings, there are still

some doubts about how specific logic will work. Is this

something RTDS can support?
