摘要
基于轨道交通供电系统与城市电网融合建设模式,对主变压电站定位的原则、方法、依据开展研究,指出城市电力系统是轨道交通供电系统的基础网,脱离母网研究轨道交通供电系统主变压电站的定位是不科学的。探析城市电网向城市轨道交通供电系统输能的主要路径和主要方式,指出两个系统的最佳耦合PCC点(公共连接点),结合对郑州地铁1号线一期变电站定位的分析,提出主变压电站定位策略。
Based on the integrated construction mode of rail transit power supply system and urban power grid,this paper studies the principle,method and theory basis of the positioning of the main transformer power station.It points out it’s unscientific to study the positioning of the main transformer power station without studying the urban system network since it is the basic network of the former.This paper analyzes the main paths and ways of energy transmission from the urban power grid to the urban rail transit power supply system,points out the best coupling PCC points of the two systems,and puts forward the positioning strategy of the main transformer power station based on the analysis of the positioning of the phase I substation of Zhengzhou Metro Line 1.
