The dSPACE Electrical Power Systems Simulation Package allows for the real-time simulation of electrical models developed in Simscape Electrical™ (Specialized Power Systems).
The Electrical Power Systems Simulation (EPSS) Package allows for the real-time simulation of electrical models developed in Simscape Electrical™ (Specialized Power Systems). The package provides various ways to integrate Simscape Electrical™ (Specialized Power Systems) models in a dSPACE hardware-in-the-loop (HIL) environment, e.g., for testing:
The FPGA-based approach involves configuring a ready-to-use FPGA application according to the given Simscape Electrical™ (Specialized Power Systems) model. This achieves low latency HIL simulation. Using the processor-based approach, an extension library is available for modifying a Simscape Electrical™ (Specialized Power Systems) model to allow real-time-capable code generation on dSPACE real-time processors by means of Simulink Coder™.
For FPGA-based simulation, there are preconfigured FPGA applications to allow easy integration without time-consuming FPGA synthesis. In particular, no FPGA-specific knowledge or software is required. For processor-based simulation, there are mean value models for different 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.
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. Furthermore, diverse comfortable analysis tools let you examine your model with regard to stability, switch combinations, and FPGA capability.
To facilitate the simulation of large and complex topologies, the EPSS Package contains most advanced multi-processor and multi-FPGA features. The tooling for semiautomatic model separation enables you to find a stable and most performant splitting position without expert knowledge. Therefore, you can easily set up multi-processor and multi-FPGA systems by using the individual cores, processors, or several FPGA boards. This feature can significantly speed up simulations by providing an option for parallel computing and a high-performance data exchange between individual simulation platforms. Moreover, you can assign the I/O boards and inter-FPGA connections by graphical programming. Thanks to the package's seamless integration into the dSPACE tool chain, you can easily extend the functionality to established XSG-based models and high-voltage load modules.
