| 摘 要： | 通过对牵引供电系统中交直交机车运行原理的分析，建立以有功功率、功率因素、直流侧电压作为重要指标的CRH380B型机车简化模型，采用PSCAD/EMTDC搭建了机车-牵引网-电网牵引负荷联合仿真平台模型，并分析CRH380B型动车组在稳定运行时，机车位置与机车数量对电网电流谐波畸变的影响，以及机车位置对接触网电压的影响。仿真结果表明，所搭建的CRH380B型机车模型和高速牵引负荷联合仿真平台结构简单合理，能较好分析机车电流谐波特性、牵引供电系统接触网电压分布规律和电网谐波畸变特性。

| Abstract: | Through the analysis of operating theory of AC-DC-AC locomotive in traction power supply system, this paper established a simplified model of CRH380B and active power, power factorand DC side voltage act as important factors. The united simulation platform of traction loads of locomotive, traction grid and power system were built in PSCAD/EMTDC IDE. The paper analyzed the effect of running position of locomotive in traction power supply system for the voltage level of the catenary when CRH380B was in the stable operation, and the effect of locomotive position on the grid and the number of locomotive for current harmonic distortion. Simulation results show that the CRH380 model and the united model built in the paper are simple and reasonable. And they could be able to analyze locomotive current harmonic characteristic, the catenary voltage distribution of traction power supply system and the total harmonic distortion characteristics of the grid. |
