The dSPACE Electrical Power Systems Simulation Package allows for the real-time simulation of electrical models developed in Simscape Power Systems™.
The Electrical Power Systems Simulation Package allows the real-time simulation of electrical 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, e.g.:
Using the processor-based approach, a library containing equivalent models for power electronics is available for modifying a Simscape Power Systems™ model to allow real-time-capable code generation on dSPACE real-time processors by means of Simulink Coder™. The FPGA-based approach involves configuring a ready-to-use FPGA application according to the given Simscape Power Systems™ model. This achieves low latency HIL simulation.
For processor-based simulation, there are mean value models for bridge circuits used in power electronics to assure 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. The speed of both simulation types is increased by precalculating the model states. By providing model separation (model splitting), the package lets you use multiple dSPACE real-time platforms simultaneously for computation. An integrated scope function lets you capture high-frequency signals within the FPGA clock rate.
