城市轨道交通变电所综合自动化组网结构探讨

Structure of Integrated Automation Network of Urban Rail Transit Substation

介绍了重庆轨道交通1号线和成都轨道交通1号线的变电所自动化系统结构,从安全、可靠、经济、高效等方面分析了光纤环网(重庆1号线)和光纤星型(成都1号线)两种组网结构的特点。提出了一种新型组网结构形式——双星型组网结构,同时对间隔设备层中压保护装置组网情况进行了分析。

Different forms of integrated automation network of urban rail transit substation and their characteristics are in- troduced, the system structure applied in Chongqing rail transit Line 1 and Chcngdu metro Line l is analyzed from angles of safety, economy and efficiency. On this basis, a new network structurc-thc doublc-star network is proposed, the medium voltage protection device network on the interval device layer is compared and analyzed.
