A novel simulation scheme of power electronics system with the parallel inference machine (PIM)

For the dynamic simulation of a control system with power converters, the authors propose a novel scheme using a parallel inference machine (PIM), which emulates a parallel-computing machine with several hundreds of processors. Utilizing its parallel software, the simulation can be realized with a multi-layered structure, which is convenient to separately describe controllers, converters and plants. The authors examine the PIM simulator for two cases: an HVDC system and an SMES system. Simulation results were compared with analog simulator results and other simulation methods. It was concluded that power electronics control system simulation can be made on PIM without much knowledge of numerical techniques. The multilayered cell structure provides easy access to the model for modification and parameter adjustment. Improvement of the PIM itself will make this approach more powerful and possible for real-time control purposes
