我国兆瓦级交流牵引传动系统的试验研究

本文叙述了我国迄今功率最大的交流传动系统的地面试验结果。作为研制大功率交流传动干线电力机车的基础研究,所进行的试验研究对象包括四象限脉冲整流器、中间直流电路和脉宽调制逆变器,即为交-直-交电压型变流器,同时还研制了适合机车牵引用的电子控制装置。文中阐述了交流传动电力机车的特征、试验系统的方案选择、系统及部件的设计原理,最后给出了系统试验结果,包括1025kW的牵引特性、800kW的再生制动特性以及有关数据。

Test Study on Megawatt-rated AC Traction Driving System in our Country

The paper describes simulation test result for the AC driving system of the highest power to date in our country. As the basic research on mainline high power AC driving electric locomotive, its study objects contain fourquadrant pulse rectifier, intermediate DC circuit and PWM inverter, i.e.AC-DC-AC voltage source convertor. Besides, electronic control device for the locomotive has been developed. It is depicted in this article the features of AC drive electric locomotive, test system option, design principle for the system and its components. Finally, the test result for the system is given, including traction characteristics for 1025kW, regenerative braking characteristics for 800kW as well as relevant data.
