摘　　要：随着城市经济的快速发展,中心城市对周边地区的影响和带动作用越来越大,逐渐形成了中心城市和周边地区的都市圈发展概念,都市圈的发展使得中心城市与周边地区的客流量逐渐增大,对公共交通的需求增大,市域郊铁路的建设能够很好地解决中心城市和周边地区的衔接问题,带动沿线地区发展,为经济注入新的活力。市域郊铁路采用交流或直流牵引供电制式,车站设置降压变电所,全线降压变电所通过中压网络连接,保证供电的可靠性。中压网络也有多种电压等级,选择适合对应工程的中压网络电压等级对供电系统方案至关重要,结合目前国内市域郊铁路的建设情况,中压网络电压等级的选择应结合线网规划、资源共享、工程投资、运营维护等多方面来综合考虑。本文以温州市域铁路S3线工程的中压网络电压等级的选择为例,从线网规划、工程投资及资源共享等多方面综合分析介绍本工程的中压网络电压等级的选择。With the rapid development of urban economy,the central city has more and more influence and driving effect on the surrounding areas,and gradually formed the concept of metropolitan area development of central city and surrounding areas.The development of metropolitan area makes the passenger flow between central city and surrounding areas gradually increase,and the demand for public transportation increases.The construction of suburban railway in the city can well solve the connection problem between central city and surrounding areas,drive the development of areas along the line,and inject new vitality into the economy.The suburban railway adopts AC or DC traction power supply system,and the station is equipped with step-down substations,which are connected through medium voltage network to ensure the reliability of power supply.There are many voltage levels in medium voltage network,so it is very important to choose the voltage level suitable for the corresponding project for the power supply system scheme.Combined with the current construction situation of suburban railways in China,the selection of voltage level of medium voltage network should be comprehensively considered in combination with network planning,resource sharing,project investment,operation and maintenance,etc.Taking the selection of medium voltage network voltage grade of S3 line project in Wenzhou as an example,this paper comprehensively analyzes and introduces the selection of medium voltage network voltage grade of this project from the aspects of network planning,project investment and resource sharing.
