摘　　要：针对枢纽牵引供电系统严重的谐波问题,基于实测数据进行剖析、分类,建立枢纽牵引供电系统数学模型,并结合实测数据建立牵引负荷非耦合谐波诺顿模型。最后,仿真分析了多种枢纽牵引供电系统实际运行工况,得到了其谐波特性。For the serious harmonic problems of the hub traction power supply system,the mathematical model of the traction power supply system of the hub was established based on the measured data for analysis and classification.The uncoupled harmonic Norton model of traction load was established based on the measured data.Finally,the actual operating conditions of various hub traction power supply systems and obtains their harmonic characteristics were analyzed through simulation.
