摘　　要：配电网侧的终端通信接入方式多样,但多种通信接入方式之间并未完全实现互联互通,导致通信可靠性较差,因此,实现终端多种通信接入方式自动切换与多网融合,进而提高配电网通信网可靠性具有重要意义。基于对双向转发检测(bidirectional forwarding detection,BFD)链路双向监测、单刀双掷隔离、旁路(Bypass)技术及隧道技术等多种成熟技术在通信网络中广泛应用的研究,提出了提升配电网可靠性的关键技术和相融合的方法,并搭建实物仿真环境验证所提方案的可行性。仿真验证结果表明,所提方案能够很好地适用于复杂的配电网通信网络,从而提升其自愈能力,满足物理隔离要求以及业务传输对时延的要求,进而提升整个配电网通信网络的可靠性。The access methods for terminal communication on the distribution network side are diverse.However,due to the lack of complete interconnection among various communication methods,the reliability of communication is compromised.Therefore,it is of great significance to realize automatic switching of various communication access modes and multi-network integration of terminals to improve the reliability of distribution communication network.Based on the research on the wide application of mature technologies such as bidirectional forwarding detection(BFD)link bidirectional monitoring,single-pole double-throw isolation,Bypass technology and tunnel technology in communication networks,the key technologies and integration methods to improve the reliability of distribution network were put forward,and the feasibility of the proposed scheme was verified by building a physical simulation environment.The simulation results show that the proposed scheme can be well applied to the complex distribution network,so as to improve its self-healing ability,meet the requirements of physical isolation and service transmission delay,and improve the reliability of the entire distribution network.
