摘要

直流自耦变压器(DCAT)牵引供电系统(TPSS)在解决轨道电位和杂散电流问题方面具有优势。然而，由于TPSS的高功率水平和高运行密度，在实际的城市轨道交通系统中进行验证难度大，成本高。为此，本文提出了一种新型的直流牵引系统硬件仿真器(DC- tshe)，利用静态电力电子电路来验证DCAT-TPSS的输出性能。首先阐述了DCAT-TPSS的结构和工作原理，然后详细分析了DCAT-TPSS的轨道电位分布规律。此外，还通过仿真模型和实验室样机验证了所提出的DC-TSHE的可行性。仿真和实验结果验证了所提出的DC-TSHE的可行性和有效性。

DC Traction System Hardware Emulator for Rail Potential Distribution in DCAT Traction Power Supply System

Direct current auto-transformer (DCAT) traction power supply system (TPSS) shows advantages in solving the rail potential and stray current issues. However, due to the high power level and high operation density in TPSS, it is difficult and costly to verify in the real urban rail transit system. Thus this paper proposes a novel DC traction system hardware emulator (DC-TSHE) for verifying the output performance of DCAT-TPSS by employing the static power electronics circuits. The configuration and operation principle are demonstrated firstly, and then the rail potential distribution laws of DCAT-TPSS are analyzed in detail. Moreover, the feasibility of the proposed DC-TSHE is also verified through simulation model and laboratory prototype. Both the simulation and experimental results verify the feasibility and effectiveness of the proposed DC-TSHE.
