摘要
EPON系统因其具有高带宽、低成本、易使用、易升级的优良特性而越来越多地被应用到电力系统配电自动化通信系统中,因此对其安全性和可靠性也提出了更高的要求。为使EPON系统更好地服务于电力系统配电通信网的建设,介绍了EPON的技术特点以及EPON系统的保护方式,分析了不同厂家设备"手拉手"结构保护的实现机制及其实现的差异性,总结了"手拉手"保护组网的注意事项,并提出了一种"手拉手"保护在配电自动化通信网中的应用方案,可作为配电网EPON系统"手拉手"组网建设的参考。
EPON system is applied in the distribution automation communication system of power system more and more widely because of its characteristics of high bandwidth, low cost, easy to use and convenient for upgrade. Meanwhile, higher requirements for security and reliability are also put forward to the EPON system in power grid. The characteristics of EPON technology and the protection modes of EPON are introduced in this paper to develop the power system distribution communication network construction better. This paper also compares the discrepancy of the protection mechanism of ＇hand-in-hand＇ mode from different manufacturers and summarizes the precautions of ＇hand-in-hand＇ protection networking. Finally, this paper proposes an application solution of ＇hand- in-hand＇ protection for the distribution automation communication system. This application solution can be used as a reference for ＇hand-in-hand＇ protection networking construction of EPON system.
