既有电气化铁路牵引网电压损失改善措施研究

摘要

This paper presents the basic theory of traction network’s voltage loss of existing electric railway, a simulation model of traction power-supply system is presented to analyze it exactly. In order to reduce the voltage loss, two measures are adopted and the effectiveness is verified by simulation, and the harmonic character is also analyzed.%阐述了电气化铁道牵引网电压损失形成机理并作了相关理论计算,建立了牵引供电系统模型并进行分析,利用仿真软件对采用的两种改善方案进行了仿真验证,分析了改善效果及谐波特性。
