dSPACE Electrical Power Systems Simulation Package

The dSPACE Electrical Power Systems Simulation Package allows the real-time simulation of electrical models developed in Simscape Power Systems™.

Application Areas

The dSPACE Electrical Power Systems Simulation Package allows for the real-time simulation of electrical power system models developed in Simscape Power Systems™ (formerly SimPower­Systems™). The package provides various ways to integrate Simscape Power Systems™ models in a dSPACE hardware-in-the-loop (HIL) environment for processor-based and FPGA-based simulation. Typical applications are:

  • Wind turbines
  • Photovoltaic arrays
  • Micro grids
  • Smart grids

For processor-based simulation, there are mean value models for bridge circuits used in power electronics to assure the precise simulation of power semiconductor switching devices. Library functions for easy integration of multirate systems help avoid interference effects. For FPGA-based simulation, there are preconfigured FPGA applications to allow easy integration without time-consuming FPGA synthesis. In particular, no FPGA-specific software is required.

To enhance simulation speed and reduce memory consumption, Simscape Power System models can be divided into submodels and distributed to multiple processors or FPGAs to perform parallel real-time simulations. This makes it possible to simulate larger models in real-time.
