摘　　要：牵引供电系统阻抗是指从机车或动车组受电弓处向牵引网看去的端口输入阻抗,其在宽频带范围内的变化特性在供电能力评估、稳态潮流计算、谐波谐振治理、机车控制优化等领域均有重要作用。本文对自主研制的牵引供电系统宽频带阻抗测试技术及首套装置进行介绍,并进行测试应用,获得了京沈高铁阜新供电区间8种供电方式下的16组测试数据。本文研究成果验证且丰富了电气化铁路牵引供电专业理论,为既有线供电安全运维、新建线路联调联试提供有力保障,也为未来光伏、风能等清洁能源接入电气化铁路稳定可靠运行提供技术和设备支撑。The impedance of traction power supply system refers to the input impedance of the port seen from the pantograph of locomotive or EMU to the direction of the traction network,its variation characteristics within the range of wide frequency band plays an important role in fields of assessment of power supply capability,calculation of steady state power flow,harmonic resonance treatment,optimization of locomotive control and other fields.The paper introduces the self-developed broadband impedance testing technology and first set of devices for the traction power supply system,its testing and application as well as the 16 sets of data obtained from the tests under 8 types of power supply modes in Fuxin power supply section of Beijing-Shenyang high-speed railway.the results of research verify and enrich the theories of traction power supply system of electrified railway.they are able to provide either the powerful assurance of safety operation and maintenance of power supply of existing line,integrated commissioning of newly constructed lines or the technical and equipment support for introducing of photovoltaic,wind energy and other clean energy into the power supply system of electrified railway.
