Watch our latest webinar where we’ll introduce the newest solution for power electronics modelling with the RTDS Simulator: the Universal Converter Model (UCM).
The UCM offers unique advantages and capabilities, representing a step change in the industry when it comes to real-time power electronics simulation and the hardware-in-the-loop testing of power electronics controllers.
The UCM takes a Descriptor State Space modelling approach, and can achieve accurate switching at over 100 kHz in the Substep environment via an Improved Firing algorithm. In the Mainstep environment, in the 30-50 microsecond timestep range, the UCM allows for accurate switching in the 3 kHz range – without decoupling at the DC bus.
- Get a brief history of converter modelling with the RTDS Simulator and a review of models and approaches
- Learn the details, benefits, and applications of the new UCM
- Watch a software demonstration via RSCAD screenshare
- Q&A with an expert in power electronics modelling
Note: This webinar does not include a detailed introduction to electromagnetic transient (EMT) simulation or real-time operation. To learn more about these topics, listeners should watch this short video before joining.
RTDS Simulator users can access the demo case files via the Downloads section of the RTDS Client Area. Some changes need to be made to the cases if they are run in RSCAD FX, so please view the Q&A Document for a list of those changes.
Please note the following errata from the webinar presentation:
- For validation of the UCM, a single-phase fault case was used (not a three-phase fault, as was erroneously mentioned in the presentation).
- For the STATCOM demo case, when Vac_ref = 1.0, the currents of the “Improved FP” with 5 μs has more non-characteristic harmonics. We are still investigating this difference.
