We are excited to be bringing our popular RTDS Simulator Introductory Training Course to the USA! Join us in July for our 5-day course that focuses on the basic use of the RTDS Simulator’s hardware and software. This hands-on course is led by our industry experts from RTDS Technologies and Nayak Corporation. By the end of this course participants will be able to assemble and run simple power systems simulation cases in RSCAD, be familiar with the I/O features of the RTDS Simulator, as well as, connect a physical device to the RTDS Simulator for closed-loop testing!
Want more information? Head over to Training Courses page for more information or to register!
We’d love to hear from you! Is there a topic that you’d like to see covered in one of our Advanced Applications courses? Let us know!

We are excited to be bringing the 2018 User’s Group Meeting to Belgium!
Join us October 10 & 11 at Energyville in Genk, Belgium for this can’t-miss event!
We’re looking for RTDS Simulator users to share their work, experiences and accomplishments at this year’s User’s Group Meeting! If you have a project that the RTDS Simulator has played a key role in, we’d love to hear about it! Your participation not only help us as we continually develop new features and technologies, but it helps other users and inspires them to explore new applications!
Interested? Email email@example.com to submit your abstract! All abstracts should be a brief, one or two paragraphs, describing the presentation. There is no paper requested. In addition to the abstract, please send a colour photograph and a brief biography. This information will be published in the event program.

Average Models for Distributed & Renewable Energy Simulation
Power electronic based distributed energy resources such as wind, PV, fuel cells and energy storage are increasingly being integrated in distribution grid systems. Small simulation time-steps (< 4µsecs) are required to accurately model the high switching frequency transients in modern power converter circuits. Detailed modelling of the switching topology in power electronic converters for renewable generation require increased computation demand and place a limitation on the size of the power system that can be simulated.
For certain applications, such as the design of smart grid /microgrid control systems at the distribution level, the switched topology model of the power converters are not required in the simulation model and can be replaced with dynamic average models. In the RTDS Distribution Mode, the time-step is increased to allow for modeling large power systems. The increased distribution mode time-step is too large to simulate the high switching frequency transients of converter models. Dynamic models that represent the control dynamics and terminal AC and DC voltage-current relationships with sufficient accuracy and reduced computational resources are required for distribution applications.
Dynamic average value models use circuit elements and dependent sources to represent the voltage and current relationship on the AC and DC sides with the same control circuit as the switched converter model but neglect the firing pulse generation and switching transients. Large simulation time steps and an increased network size can be simulated with reduced computation burden.
Available models for distributed resource simulation with reduced computation burden in the RTDS library are:
- Figure 1: Dynamic PQ sources provide current injections based on given setpoints
- Figure 2: Single and Three phase average models to interface DC sources (PV, Battery)
- Figure 3: Three phase average models to interface AC sources (DFIG, PMSM).
The latest average models are available in RSCADv5.003.3 and higher. A Draft library search using keyword average will display the available components.
For simulation cases using these models, please email firstname.lastname@example.org

Team RTDS wins 1st Place at the University of Manitoba’s Make Your Move Challenge!
For the second consecutive year, RTDS Technologies joined the University of Manitoba’s Make Your Move challenge organised by WISE Kid-Netic Energy. Sixty grade 8 girls gathered at the University of Manitoba Engineering Atrium to design a device which will help a person with less mobility in their hands to grasp, let go, and move objects from one location to another, while also extending their reach by at least 30cm. Each team was mentored by a local female engineer and our Udeesha Samarasekera mentored the RTDS team of girls from Samuel Burland School! Udeesha loved their positive energy, teamwork, and determination as they narrowed down on their final design. Team RTDS received a total of 145 points landing them at 1st place with a whopping lead of 46 points!
The success of the team boiled down to these four concepts:
- Getting a clear picture of the objectives and desired outcome: Team RTDS discussed the objectives and studied the objects that they had to pick up even before finalizing their first design!
- Designing with the end-user in mind: This device helps someone with less mobility in their hands. With enthusiasm, one of the girls said, “I only have to move my thumb to operate this device!” During lunch break, her face lit up as she easily picked up her pop can and took a sip!
- Keeping on schedule: Team RTDS aimed for simplicity which allowed them to have plenty of time for testing and re-design within the 1.5hr time limit.
- Testing and Re-design. Team RTDS based their design on successful devices such as kitchen tongs, and crucible tongs. The girls suggested that the end of the device should have a large surface area with the perimeter studded with hot-glue for gripping objects. In the testing phase, they saw that some objects slipped out of their grasp. They rushed back to add toothpick “teeth” along the perimeter which did the trick!
The girls had lots of fun and learned important concepts from this design challenge! The event was held in conjunction with International Women’s Day to celebrate women’s achievements throughout history. We know that the girls in Team RTDS have a bright future ahead of them!

RTDS Technologies makes waves with the world’s most robust tool for testing traveling wave protection devices in a closed loop
The emergence of traveling wave line protection and fault location is a true breakthrough in the power industry, improving power system performance by increasing transient stability margins, increasing public and personnel safety, and limiting equipment wear and damage. The ultra-high-speed protective devices incorporating these techniques trip securely in a few milliseconds, record events in the MHz sampling rate range, and locate faults with unprecedented accuracy. With the release of our new TWRT functionality, the RTDS Simulator enables our users to comprehensively and flexibly test traveling wave protection devices in a closed loop.
Accurately test traveling wave protection and fault location (found in the SEL-T400L) in a closed loop with the simulated power system
The industry’s only tool with robust Frequency Dependent Phase Domain transmission line models operating at the necessary small timestep for traveling wave testing
Multiple line segments represent physical transposition and allow fault modeling at multiple locations
Why TWRT will be the world standard in traveling wave testing
TWRT was developed by RTDS Technologies’ world-class power system protection experts. The tool and models involved have been specifically designed to accurately represent traveling wave attenuation and dispersion for proper performance analysis of traveling wave protection and fault locating. Robust and accurate models developed by applications specialists is what makes the RTDS Simulator the world standard for the closed-loop testing of protection and control equipment.
Two hardware options for varying capabilities and budgets
TWRT’s high-speed frequency dependent phase domain transmission line models can run directly on the powerful multicore processor-based NovaCor simulation hardware. This is a highly flexible and expandable option with the ability to simulate larger systems – for example, parallel line schemes.
Using the dedicated GTFPGA Unit running the TWRT firmware allows for the high-speed simulation of frequency dependent phase domain transmission lines in parallel with the rest of the real time simulation running on main processing hardware. The GTFPGA Unit is a low-cost option that can be used in cases where small- or medium-sized systems are being simulated. GTFPGA-TWRT is directly interfaced with the small timestep simulation environment via a fibre cable.
GTFPGA-TWRT is compatible with both NovaCor and PB5 processor card-based simulation hardware.
