OPAL-RT Real-Time Simulation Software

OPAL-RT provides two primary software platforms (HYPERSIM and RT-LAB) that can each be customised for application-specific needs via a range of optional solvers, model libraries, editors, etc. These facilitate diverse Model-In-The-Loop, Software-In-The-Loop, Hardware-In-The-Loop and Power-Hardware-In-The-Loop simulations, with real-time simulation resolutions as fine as 2ns (2GHz) possible via dynamic, parallel processing on the simulator hardware CPUs and FPGAs.

All OPAL-RT's software suites can be used for 'offline' model development and verification (ie on your PC without the need for connection to the real-time simulator hardware), as well as for running 'real-time' simulations on the simulator hardware, using those models (where the simulation is optimised automatically and dynamically by sharing the computational load between the simulator's available CPUs and FPGAs).

HYPERSIM lets engineers build powerful network diagrams and populate them with real-world-validated component models ready for simulation and analysis. Alternately, non-real-time Simulink or Simscape Power Systems (SPS) models can be imported via the drag-and-drop interface.

It 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 busses.

Compatible modelling environments:

  • Simulink
  • Simscape Power Systems (SPS)

    Suite Options

    Add visualisation, automation and power electronics modelling capabilities to HYPERSIM with these optional software tools.

    ScopeView is supplied bundled with HYPERSIM. It allows users to visualise simulation data and create informative charts, perform extensive and advanced calculations, and produce detailed PDF reports.

    RT-Lab is the core product 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 modelling functions between the simulator CPUs and FPGA, as well as communication to 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 that allow models created using other non-real-time modelling tools to be utilised in the OPAL-RT real-time environment.

    Compatible modelling environments:

  • Simulink, Simscape Power Systems (SPS), SPS 'Battery Model Blocks' & Stateflow
  • PLECS, PSIM, NI Multisim and LabVIEW (requires eFPGASIM 'eHS Solver' option)
  • PSS/e, CYME, Power Factory and FMI (requires ePHASORSIM option)

    Suite Options

    Add enhanced simulation capabilities to RT-Lab with this extensive range of options from the eMEGASIM suite.

    RT-Events is an optional Simulink toolbox that allows fixed-step simulations of hybrid systems involving asynchronous events (ie with respect to the simulation clock). It is specifically intended for the simulation of high frequency modulation signals and power electronic controls.

    eHS Solver allows models created in SPS, PSIM, PLECS or Multisim to be brought into the RT-Lab simulation environment. It automatically programs the simulator FPGA to address higher resolution simulations in the 2ns - 2us time-step range, without users needing any FPGA or VHDL programming expertise.

    RT-XSG is an option that provides ready-made Simulink functional blocks for FPGA Hardware-in-the-Loop and Rapid Control Prototyping simulations. It allows users to custom configure the simulator's FPGA and to manage high-bandwidth data transfer between the RT-LAB software running on the CPU cores and the user-defined systems on the FPGA.

    The eFPGA Electric Machine Library option (now included with RT-XSG) provides a wealth of device models, including permanent magnet, asynchronous machines, stepper and other motor and generator types. The models contain dedicated I/Os for PWMs, resolvers, encoders and hall effect sensors. All I/Os can be reconfigured through the RT-XSG option and the models themselves can be edited via the eHS front end.

    The MMC FPGA blockset simulates MMCs with very high fidelity and unbeatable efficiency. The models can be seamlessly integrated into a complex electric circuit simulated in eFPGASIM/eHS (see also HYPERSIM). The blockset is directly accessible from MATLAB/Simulink, enabling users to further edit models and produce their own FPGA firmware (see also RT-XSG option) for integrating special I/O interfaces or customised control algorithms.

    Performs real-time and faster-than-real-time transient stability simulations for transmission and distribution grids with thousands of 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 simulation of large-scale networks (as large as 106,000 nodes verified) within a real-time simulation environment.

    It allow 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.
