摘要

随着电气化铁路在现代铁路运输中的广泛应用，牵引负荷在电力负荷中所占比重越来越高，对电网产生的影响不容忽视，但当前对牵引变电站综合负荷特性的研究比较薄弱。在系统分析电气化铁路牵引供电系统的组成结构及运行特性的基础上，提出一种基于电气化铁路牵引供电系统实际负荷构成特性的“感应电动机并联牵引电机和恒阻抗”的机理负荷模型。该模型结构简单，物理意义明确，使用方便。基于Simulink仿真平台测量数据的总体测辨建模表明，模型具有良好的描述能力，可以作为研究电气化铁路牵引负荷对电力系统影响的实用负荷模型。

Abstract

With the fast development of electrified railway， the proportion of traction loads in the power system is increasing， which imposes effect on power system stability. However， the research on the synthesis load characteristics of traction power supply system is still weak. to solve the problem， a novel load model is introduced based on the actual load structure of the traction power supply system， which consists of an induction motor and a traction motor and constant impendence model. The model has simple structure， clear physical meaning and easy to use. The model is verified by simulation using Simulink. The results show that the model reflects a real traction system， and can be used in studying the effects of electrical railway on the power system.
