Utilization of Regenerative Braking Energy and Energy Saving Analysis for Shuozhou-Huanghua Railway

为研究朔黄铁路神池南至定州西段再生制动能量利用情况,本文根据实际运行的两种车型分析了再生制动能量产生原理和流向,利用OpenTrack和OpenPowerNet软件建立牵引供电系统模型,以50%HXD1机车上线比例作为初始值,对6种工况进行仿真,得到HXD1、SS4B机车实际运行功率曲线以及6种工况下牵引变电所总功率曲线和能耗,分析得出再生制动能量利用率和节能情况,并针对优化再生制动能量技术方案提出明确建议。

In order to study the utilization of regenerative braking energy of Shenchinan to Dingzhouxi section on Shuozhou-Huanghua railway,this paper analyzes the generating principle and flow direction of regenerative braking energy based on the two models of locomotives which are being in service on the line concurrently.A model of the Shuozhou-Huanghua railway traction power supply system is established by adopting of OpenTrack and OpenPowerNet software,with 50%of HXD1 locomotives being in service on the line as the initial value,six operating conditions are simulated to obtain actual power curves of locomotives of HXD1 and SS4B,as well as the total power curves and energy consumption of the traction substation under six operating conditions.The utilization rate of regenerative braking energy and energy saving are analyzed,and clear suggestions with regard to optimizing the technical scheme of regenerative braking energy are put forward accordingly.
