Real-Time Hardware-in-the-Loop Emulation of High-Speed Rail Power System With SiC-Based Energy Conversion

Real-time device-level hardware-in-the-loop (HIL) emulation of a complete high-speed rail system is challenging due to its complex modeling and high computing demand. With higher energy-efficient and switching frequency semiconductor material being found and adopted in the power electronic electrified traction application, there is a need to develop such new material based real-time device-level power electronic models in the modern and future traction system to estimate and verify the device switching transients, energy efficiency, and power quality improvement capability. This paper proposes a real-time SiC IGBT model based on the Wiener-Hammerstein configuration. A complete Beijing-Shanghai AC traction application is utilized as the study case, implemented on the hybrid multiprocessor system-on-chip (MPSoC) and field-programmable gate array (FPGA) platform, to verify both the system-level and device-level performance of the proposed model with comparisons to commercial software PSCAD/EMTDC and SaberRD. The dedicated hardware implementation enabled model execution at $10~ns$ for device-level transients and 10 μs for system-level transients.
