智能配电网光纤通信技术选择

Selection of Optical Fiber Communication Technologies for Distribution Network

摘要: 本文对工业以太网交换机和EPON技术在配网中应用中的几个关键问题进行了对比，并结合中压配网一次结构和配电自动化、用电信息采集业务节点布置情况，选择适宜的光纤通信技术。配电自动化业务应用光线通信网络宜采用环型结构，优先采用工业以太网交换机；在用电信息采集业务应用光线通信网络时，宜根据光缆建设是环型或星型结构，相应选择采用工业以太网交换机或EPON。

Abstract: This paper compares several key problems in the application of industrial Ethernet switches and EPON technology in distribution power network, combined with a structure of medium voltage distribution network and distribution automation, electrical layout information collection service node, selecting the appropriate optical fiber communication technology. Distribution automation business application light communication network should use the ring structure, giving priority to the adoption of industrial Ethernet switch; the electric energy data acquisition application light communication network should be based on fiber optic cable construction which is a ring or star structure, to select using industrial Ethernet switches or EPON accordingly.
