  • DistribuTech 2019!

    January 17, 2019

    The RTDS Simulator is the leading real time simulation tool for grid modernization. At DistribuTech, our experts can walk you through the interfacing process that allows power system engineers to test protection and control systems comprehensively prior to commissioning. Join us in observing the interaction between an SEL® Real Time Automation Controller and a simulated microgrid based on a real industrial park in the United States. Plus, have your questions answered and learn how real time simulation can be adapted for your grid modernization project.

  • Hot Topic: Interfacing RTDS Simulator to External Equipment Using Aurora Protocol

    October 31, 2018

    The Aurora protocol is a lightweight serial protocol developed by Xilinx that is suitable for high speed point-to-point communication links. Support for the Aurora protocol exist for PB5 and NovaCor based RTDS Simulators and is available within both the main timestep and small timestep simulation environments.  Aurora specifications for the PB5 and NovaCor hardwares are similar but slight differences do exist.  The overview provided here focuses on the NovaCor implementation.

    The RTDS Simulator’s Aurora protocol implementation allows the bi-directional exchange of 32-bit integers or floating point numbers between the simulator and another Aurora protocol compatible device.  Signals are exchanged via a fiber optic cable. 

    The ability to output or read-in Aurora formatted packets must be licenced for each PB5 card or NovaCor chassis.  Each license allows for interconnections over 4 different fiber optic cables.  Each fiber optic connection supports the output of 1-64 numbers as well as the input of 1-64 numbers.

    In order to read or write Aurora data to/from a fiber optic cable, either the mainstep or small timestep Aurora components must be used in DRAFT.  Both of these icons are shown below and can be found if the keyword ‘aurora’ is used to search the master library.


    Using the Aurora Protocol to exchange data with and external device is an attractive option in cases where a lot a data needs to be moved in a short period of time.  The other IO cards and not ideal for such applications.  The data exchange between the RTDS Simulators and an Aurora-compatible device can be either unidirectional or bi-directional.  The number of signals exchanged and the direction of that exchange is generally application specific.

    Examples of Interface options: (1/2) Unidirectional, (3) Bi-directional




    Tighter Closed-Loop Performance using Sequence Numbers

    For certain applications, data will be sent from the RTDS Simulator to an external device and the device will provide a response that should be read back into the simulation.  For such scenarios, we’ve introduced something called a sequence number that is useful for minimizing loop delays and improving closed-loop performance.

    A sequence number is an integer that is appended to the package of data sent to an Aurora compatible device.  This integer is incremented every timestep.  When the sequence number option is enabled in the Aurora DRAFT component, the component will send out its package of data (including the sequence #) and then its execution is paused until the sequence number of an incoming data package matches the one sent out.  NOTE: The Aurora compatible device is expected to echo the sequence number it receives.

    Use of sequence numbers makes it possible to send out data to external device using the Aurora protocol and then receive a response to that data within the same timestep.  This of course assumes the device is able to respond in significantly less time than a timestep.  Interfacing time delays can therefore be minimized.

    *Due to performance constraints sequence numbers are not available for the small timestep Aurora component.

    Aurora Interface Details

    When generating the Xilinx IP Aurora core to connect to the NovaCor Aurora link, the following settings are required:

    • Aurora lanes : 1
    • Encoding: 8b/10b
    • Lane Width : design dependent
    • Interface : Framing
    • Dataflow Mode : Duplex
    • Flow Control : None
    • Line Rate : 2 Gbps
    • Scrambler/Descrambler: No
    • Little Endian Support: No
    • CRC: No

    Additional Resources

    A demo case that includes a reference FPGA design that can be loaded onto a Xilinx VC707 board is available to provide a starting point for customers wanting to use the Aurora protocol to communicate between the RTDS Simulator and an external device.

    WPRC 2018

    traveling wave relay testing

    For many years, developers have investigated the possible use of traveling wave data for protective relaying applications.  Now the first commercial devices using traveling wave based algorithms have been released.  These new devices use sampling in the range of 1 MHz to very accurately measure the timing of reflections caused by faults. This creates a challenge for closed-loop testing of these relays with a real time simulator.  In order to test the traveling wave based relay algorithms, the simulator must operate with a timestep in the microsecond range, whereas previously protective relays were tested using timesteps in the 50 microsecond range.

    Join us at WPRC where we will be demonstrating NovaCor, which has the processing power to provide a flexible, high fidelity modeling capability well-suited to testing traveling wave based relays.  The raw processing power of NovaCor helps to facilitate simulation timesteps in the microsecond range.

    CIGRE Canada


    Learn about our GTFPGA MMC models capable of modelling up to 1024 SM per valve with half, full and mixed topology. We will be demoing the HVDC point to point and DC grid systems developed by CIGRE working groups.  See NovaCor’s ability to model large DC grids on a single NovaCor chassis!

    Also learn about GPES, our new general power electronic solver that’s runs on the GTFPGA unit. GPES provides a highly flexible platform to model custom converter topologies. Compared to our small time step environment, GPES will support more nodes, more switches, and more branches with a reduced time step size!

    IEC 61850 Global

    Real time closed-loop testing is the most thorough test method for relay engineers and has become an integral part of the daily testing tools. This closed-loop testing provides a method of not only evaluating the performance of the protection equipment, but also evaluating the response of the power system network to the operation or mis-operation of that protection device. To achieve this, a simulator that emulates various conditions of the physical power system would be required. Then the system voltages, currents, and the breaker status would need to be send from the simulator to the protection device, and also the trip, reclose signals from the device under test need to be fed back to the simulated system. The data exchange can be well handled by the IEC 61850 Sample Values, GOOSE messages and through MMS communications.

    The RTDS Simulator’s IEC 61850 communication capability is provided by the GTNETx2 card and the GTFPGA-SV board. A closed-loop relay testing will be demonstrated using IEC 61850 at the RTDS booth. Some new developments, including new models for supporting IEC 61850 Edition 2 will be presented as well. A presentation on integrated testing for IEC 61850 compatible IEDs in a simulated smart automation system is scheduled in the morning session of Day 2 program.
