The detailed real-time simulation of MMC-based HVDC links is one of the most challenging tasks in power system validation today, requiring the combined use of CPU and FPGA technologies. The inclusion of surge arresters in the real-time fault tests further increases the difficulties because of the highly non-linear characteristics of such protective devices. In this paper, the OPAL-RT digital real-time...
Current control systems and emulation systems (Hardware-in-the-Loop, HIL or Processor-in-the-Loop, PIL) for high-end power-electronic applications often consist of numerous components and interlinking busses: a micro controller for communication and high level control, a DSP for real-time control, an FPGA section for fast parallel actions and data acquisition, multiport RAM structures or bus systems...
In many power electronic applications the request of short development time demands reliable simulation studies to prove the control concepts in early developments stages and avoid critical behavior in real application. Simulation studies are sufficient to prove the general behavior of a control code. However, the platform architecture of the target hardware influences control behavior and code stability...
