摘要

光伏发电是一种绿色节能的发电技术，近年来在电力系统中得到大力发展，但在牵引供电系统中尚未有工程应用。针对光伏接入牵引供电系统的情况，提出了一种利用光伏能源来降低牵引供电系统负序的方法。根据牵引系统供电臂负荷电流差值选择光伏接入方式，采用理论分析了改善牵引供电系统负序的基本原理，提出了相应的控制方法。针对不同的负荷情况，在MATLAB/Simulink仿真平台上搭建了电气仿真模型进行分析，仿真结果表明所提方法和控制策略能有效改善牵引供电系统负序电流问题。

Abstract

Photovoltaic (PV) generation is a green energy-saving power generation technology that has been vigorously developed in power system in recent years

but there is no engineering application in traction power supply system. Aiming at the situation of photovoltaic access traction power supply system

a method of using photovoltaic energy to improve the negative sequence of traction power supply system is proposed. According to the load current difference of power supply arm of traction system

theoretical analysis is used to select the photovoltaic access method and to improve the basic principle of the negative sequence of traction power supply system

and then the corresponding control method is proposed. According to different load conditions

the electrical simulation model is built on the Matlab/Simulink simulation platform. The simulation results show that the proposed method and control strategy can effectively improve the negative sequence problem of traction power supply system.
