摘 要
城市轨道交通作为一种运量大、速度快、污染少、舒适性好的交通工具,很有力的缓解大中型城市乘车难、环境污染及交通拥堵等难题。近年来我国着力发展城市轻轨和地铁,本文主要以地铁作为研究对象。城市轨道交通站间距离短、运行密度高,机车频繁制动吋产生相当可观的再生能量,将产生的能量得以利用,不仅节约能源、保护环境同时降低电压利于机车安全运行。再生制动产生的能量得以利用是本文研究的重点,提出逆变电阻混合型再生制动能量吸收方案。本课题以建立地铁再生制动及能量吸收仿真平台为目的,利用仿真软件建立机车运行制动模型及混合型能量吸收模型。首先,分析和总结几种城市轨道交通车辆制动方案的优缺点,重点研究馈能型再生制动方案的基本原理及主要技术问题,提出逆变电阻混合型再生制动能量吸收方案。然后基于电阻制动原理,结合逆变并网电阻制动方案进行建模、仿真分析,并对再生制动产生功率及电流进行粗略的计算。 关键词:再生制动;逆变并网;电阻制动

Abstract
As a large capacity, fast speed, less pollution and comfortable transportation, urban rail transit effectively alleviate the transportation pressure of the large and medium-sized city, environmental pollution and traffic congestion . In recent years, China began to develop the light rail transit and subway. The subway stations has shorter distance and locomotive has haig density running. During locomotive frequently braking, it produced considerable regeneration energy. Reasonable utilization of the regeneration energy not only save energy, protect environment but also reduce the regeneration energy not only save energy, protect environment but also reduce the voltage grade for the locomotive’s safety operation. This paper is the focus on utilization of the regeneration energy, and The inverter-resistance hybrid method is propose. This topic is purposed to build Metreo regenerative braking and inverter-resistance hybrid energy absorption model by simulation software.
Firstly, the urban rail transit power supply system has been introduced. Several vehicle braking scheme has been summarized and analyzed for their advantages and disadvantages. The inverter-resistance hybrid of regenerative braking energy absorption solution has been purposed. Secondly, combined with inver and resistance braking scheme, the model was built analyze and the power and current ofregenerative
