变电站光纤以太网开发及应用

Solutions of Ethernet Network in Substation

目前以太网通信已应用于变电站综合自动化系统,为了提高以太网的抗干扰能力和传输距离,开发光纤以太网产品是必然选择。针对变电站的特殊应用场合,提出介绍了自主开发光纤以太网的方案,以及光纤以太网在设计和施工时的一些注意事项。采用上述方案,可提高以太网络通信的可靠性,有利于推广以太网在变电站综合自动化系统中的应用。

Ethernet communication is applied in integrated substation automation system（ISAS） now,In order to improve Ethernet anti-jamming ability and extend Ethernet communication distance.This is necessary that fiber Ethernet products are developed. This paper shows some Ethernet advantages.Share technology,switch technology and layer 2 switches are introduced in detail.In allusion to the substation special situation,the schemes of developing fiber Ethernet products for oneself are lodged. Some notes are put emphasis on Ethernet networks design and building.
