摘要
针对用于铁路货运的直流传动SS4B型电力机车和交流传动HXD2型电力机车,结合线路实测数据,从工作原理、功率因数、谐波电流、机车能耗等4个方面进行了电气负荷性能对比,说明了交流传动电力机车的技术优势。随着直流传动电力机车的停产和交流传动电力机车的大量投运,在设计牵引供电系统时,必须充分考虑交流传动机车功率因数高、谐波电流小、能全功率范围再生制动的特点,同时,应尽快通过实测掌握各型交流传动电力机车的谐波特性,为牵引供电设计提供基础数据。
HXD2 and SS4B were selected as the representative of AC drive and DC drive electric locomotive respectively. Based on the actual measured data, their electrical load performance were compared in four aspects, i.e. working principle, power factor, harmonic current and the locomotive consumption. The technical advantages of AC drive electric locomotive were illustrated. With the production halts of DC drive electric locomotive and more and more AC drive electric locomotive putting into service, the properties of high power factor, low harmonic current and regenerative braking ability should be fully considered when designing the traction power supply system of electric railway. Meanwhile, it was also necessary to know the harmonic characteristics of AC drive electric locomotive in detail so as to provide the basic data for the designing of traction power supply system.
