The RTDS Simulator has been the world's benchmark for performing real-time power system simulations for nearly three decades.
We’ve been able to maintain this status due to a dedicated in-house team of world-class power systems modelling experts. Our RSCAD software’s modelling library is the single most diverse, flexible, and accurate real-time simulation library available.
Customer-based innovation
We have the resources and expertise to make specific models and features a reality for customers. Many of our existing models were created for ambitious users with a specific application in mind.
Unmatched user support
Our team of engineers is intimately familiar with each component and can provide prompt and comprehensive user support. Our support goes beyond simple troubleshooting, focusing on providing the user with confidence that the simulation is valid and accurate.

A convenient module for creating user-defined models, built into RSCAD
RSCAD’s Component Builder module allows the real-time code for any custom component to be created in C. The graphics and data entry menus are created using drawing facilities and GUI input. The same Component Builder module available to users has been used by the RTDS Technologies team to develop most of the models found in RSCAD.
