8 - Processor-based real-time simulation of power electronic systems

Abstract

Processor-based real-time simulation uses general computational hardware resources to compute the model. The common processors used in real-time simulations are the RISC processor, the central processor unit (CPU), the digital signal processor (DSP), and the graphics processing unit (GPU). In this chapter the hardware structure of a processor-based simulator is first given. Then the model implementation method in the real-time target processor is discussed. Afterward the choice of the numerical method is discussed using an R-L circuit as an example. Moreover the design process of converting a power converter model to a real-time simulation is presented by implementing an AC-DC-AC power electronic system in DSP. The general procedures, the involved problems, and the potential solutions are also discussed.
