城市轨道交通变电所综合自动化通信网络

Integrated Automatic Communication Network of Substation in Urban Rail Transit

认为通信网络是变电所自动化系统的关键。介绍城市轨道交通变电所综合自动化系统的结构,在分析通信网络技术特征和通信实时性要求的基础上,阐述现场总线和以太网在变电所综合自动化中适用的层次;提出在变电站自动化系统中,提高站内通信网的通信开放性的最佳途径是所有厂家都采用标准的通信协议。

Communication network is the key section in substation automation system. In this paper the configuration of the substation integrated automation system of urban rail transit is presented. Based on the analysis of the technical characteristics of communication network and the real-time demand of communication, the paper indicates the proper position where field bus and ether net are adaptable in substation integrated automation system and points out that all suppliers applying the standard communication protocol should be the most possible beneficial solution to improving the openness of communication in substation automation system.
