Abstract
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.
Highlights
High-speed rail (HSR) delivers fast, efficient, and reliable transportation in all weather conditions, fosters economic development in second-tier cities along train routes, links cities together into integrated regions that can function as a single stronger economy, broadens labour markets and offers populace a wider network of employers to choose from [1], and has been researched for stability and compensation [2]–[4], control [5], design optimization [6], and hardware-in-the-loop (HIL) application [7]
The technology of high-speed rail network is constantly evolving with the introduction of newer power semiconductor device, and an accurate and efficient hardware-in-the-loop simulation is necessary
With proper allocation of the high-sequential clocking ARM R core and massively parallel field-programmable gate array (FPGA) execution resource, real-time ultra small time-step modeling of detailed power converter system can be realized for both device-level and system-level transients
Summary
High-speed rail (HSR) delivers fast, efficient, and reliable transportation in all weather conditions, fosters economic development in second-tier cities along train routes, links cities together into integrated regions that can function as a single stronger economy, broadens labour markets and offers populace a wider network of employers to choose from [1], and has been researched for stability and compensation [2]–[4], control [5], design optimization [6], and hardware-in-the-loop (HIL) application [7]. With the advantages mentioned above, there is a growing need to model the SiC power device in the existing HSR AC traction scenarios to test and evaluate the performance of the control and protection algorithm and circuits, and controller in a device-level non-destructive environment repeatedly For this purpose, real-time HIL emulation of the HSR power system can be a promising answer in this application. This paper proposes real-time electrothermal behavioural models for the SiC hybrid IGBT module via the WienerHammerstein configuration with the equivalent electrical component representation in the study case of BeijingShanghai HSR AC traction system based on the hybrid multiprocessor system-on-chip (MPSoC) and field-programmable gate array (FPGA) platform.
