OPAL-RT Real-Time Simulation Software

OPAL-RT offers two real-time modelling environments to choose from - HYPERSIM and RT-LAB - that each supports a range of model editors, solvers and libraries.

So the notion of having to build a simulator chassis to order to address a specific need - say, grid phasor studies - simply does not apply with OPAL-RT. Instead, chassis are purchased to meet price and/or model size/complexity needs, with software then purchased to 'Customising' can be as simple as purchasing an additional software solver or I/O card or breakout box; or as complex as networking multiple simulators and I/O expansion hubs to model even the largest and most complex networks.

And with real-time modelling resolution down to 2ns (2GHz) possible with their powerful multi-PC-processor/FPGA parallel processing architecture, engineers cna achieve things simply NOT possible with PC-processor-only based modelling tools.

So spend less time configuring and more time simulating with OPAL-RT.

To start, simply click the Real-Time Simulation Software Suite Selection Guide image and resolve which software environment best meets your need.

HYPERSIM is a powerful model builder and simulation environment developed jointly by Hydro-Quebec and OPAL-RT to deliver accurate simulations of very large power grids and their equally complex control systems.

It uses a schematic builder interface similar to the network planning tools power systems engineers are already familiar with. And because it's a real-time modelling application, it lets engineers delve into network issues that network planning apps alone can't. And it does it in real-time.

If that sounds impressive, HYPERSIM is the only real-time digital simulation environment with the power to simulate and analyse very large-scale power grids with more than 2,000 three-phase buses AND run EMT pre-simulation analyses in the cloud, providing an unprecedented research, design, fault-finding and verification tool to transmission and distribution network engineers and researchers.

HYPERSIM also supports models created in:

  • Simulink
  • Simscape Power Systems (SPS)


    eHS for HYPERSIM:

    eHS is OPAL-RT's powerful electrical hardware solver that allows co-simulation of power electronics and power grids and their connected devices (switches, safety relays, etc). eHS creates custom firmware for the FPGA to manage the smaller time step sampling required for high speed switching of electronic circuits. It also also includes a native schematic editor, so you don't need a 3rd party tool such as PSIM or NI Multisim to enter electrical circuit designs into your models. Learn more >>

    HYPERSIM On Demand:

    HYPERSIM On Demand is a powerful, Amazon Cloud based pay-as-you-go simulation service. It delivers high-end capability to supplement in-house OPAL-RT platforms - or use it when you need a powerful grid simulation tool but don't have in-house RTS capability. Note: HYPERSIM Cloud excludes HIL connectivity. Learn more >>

    RT-Lab is the core tool underpinning the eMEGASIM, eFPGASIM and ePHASORSIM simulation software suites. It manages the conversion of 'non-real-time' models created in Simulink or Simscape Power Systems (SPS) into C++ 'real-time' models, and the dynamic assignment of blocks between the simulator CPUs and FPGAs, as well as communications with I/O connected devices.

    Add-on modules provide application-specific solvers and user dashboards for a wide range of power systems and power electronics studies. These include options for importing models created in other 'non-real-time' apps.

    Models supported by the core RT-Lab environment include:

  • Simulink, Simscape Power Systems (SPS), SPS 'Battery Model Blocks' & Stateflow
  • PLECS, PSIM, NI Multisim and LabVIEW (requires the eFPGASIM 'eHS Solver' option)

    Performs real-time and faster-than-real-time transient stability simulations for transmission and distribution grids with as many as 100,000 single phase buses.

    ePHASORSIM's phasor domain solver, performing at a typical time-step of few milliseconds, provides voltage and current information equivalent to those of a phasor measurement unit (PMU) installed in a power grid. This unique electromechanical real-time simulation system enables precise modelling and analysis of large-scale networks - as large as 106,000 nodes (verified) - within a real-time desk-top environment.

    It allows the development of complex transmission and distribution network models in Simulink, PSS/e and other modelling tools, which can then be verified 'offline' (ie on a PC's CPU in non-real-time mode) or 'online' (ie on the simulator hardware where dynamic optimisation shares processing tasks across available CPUs and FPGAs).

    This level of accuracy and ability to scale from the small to the very large makes it ideal for testing and integration of EMS/SCADA systems, and wide area protection and control schemes.
