摘要
在通信网可靠性分析理论的基础上,提出了针对配电通信网接入层以太网无源光网络(EPON)保护组网方式的网络可靠性分析方法。采用系统可用度理论,定量分析研究了单电源冗余保护树形网、全链型保护手拉手网、全链路保护双电源双T网、环形保护网等几种配电通信网接入层EPON保护组网方式的可靠性,并对组网成本进行了分析。讨论和总结了当前实施中的配电通信网建设和改造工程EPON保护组网的最优组网方案。
Based on the reliability theory of power communication network,reliability analytic methods are proposed for Ethernet passive optical network（EPON） protection networking of the power distribution communication access layer.By using the system availability theory,the reliability and cost of EPON protection networking are quantitatively analyzed for the access layer of four kinds of power distribution communication network,i.e.,tree-type network of single power supply redundancy protection,hand-in-hand network of whole chain protection,dual-power dual-T network of full link protection,and ring-type protection network.The optimal networking solutions are discussed and summed up for the EPON protection networking schemes of power distribution communication network in current operation.
