摘要
随着变流技术、控制技术和计算机技术的发展,城市轨道交通已成为市民出行的主要方式,为了响应国家节能降耗政策,加快建设资源节约型、环境友好型社会,开展城市轨道交通车辆辅助供电系统节能方案研究,对城市轨道交通系统能耗优化具有重要意义。文章通过分析车辆辅助供电系统主电路结构和空调等重要负载供电电路,提出一种基于高频直流斩波降压电源的车辆辅助供电系统优化方案,描述其基本原理,并通过理论计算对优化方案的节能效果进行验证。
With the development of converter technology,control technology and computer technology,urban rail transit has become the main mode for people to travel.In order to respond to the national policy of energy saving and consumption reduction,accelerate the construction of resource-saving and environmental-friendly society,and carry out the research on the energy-saving solutions of auxiliary power supply system of urban rail transit vehicles,it is of great signifi cance for the optimization of energy consumption of urban rail transit system.By analyzing the main circuit structure of the vehicle auxiliary power supply system and the important load power supply circuits such as air conditioning,this paper puts forward an optimization solutions of the vehicle auxiliary power supply system based on the high frequency DC chopper step-down power supply,describes its basic principle,and verifi es the energy-saving effect of the optimization solutions through theoretical calculation.
