摘要
通过研究典型电力机车的负荷构成特性,认为电力机车的负荷特性主要由牵引回路特性所决定.通过对系统运行于稳态和暂态两种状态下串励牵引电机特性的分析和数学模型的推导,得到脉流牵引电机的运行特性规律.利用总体测辨法,得到了能够描述牵引电机运行特性的负荷模型及参数.数字仿真结果也验证了该方法和结论的正确性和有效性,从而为研究电力机车的负荷特性及电气化铁路负荷的综合负荷特性提供了一种新的思路.
By estimating the load structure of the locomotive, it has been proved that the characteristics of locomotive depend on traction loop. By studying the steady-state and transient characteristics of traction motor, a new method for the study of the pulsating-current traction motor and synthetic load characteristics of electric railway load has been introduced. The representative parameters of traction motor have been deducted in mea- sured-based method and the results of simulation have proved the validity of the method.
