广州轨道交通延长工程供电环网拆分方案设计

广州市轨道交通二、八号线延长工程将运行的既有二号线拆分并延长,形成新二号线和八号线,其供电系统环网结构亦随之调整.由于须同时考虑既有线运行、新旧网络的衔接、工程投资及施工方案等因素,该工程的环网方案设计有特殊之处,文中对此作了详细论述.

Design of Scheme for Separation of Power Supply Loop Network for Extension Project of Guangzhou Rail Transportation

The extension project of line 2&8 divides the currently-operating line 2 into two parts,and extends them to the new line 2 and line 8.The loop-network structure of their power supply system must be adjusted accordingly.The design scheme has to consider actual complex conditions,such as the operation of existing line,the interface between old networks and new,the investment and construction plan,etc.In this paper,the special characteristic of such loop-network design is introduced in detail.
