摘　　要：智能分布式快速故障自愈技术多依赖光缆介质通信,但由于个别地段光缆敷设路径开挖难的问题,导致光缆在某些项目中无法得以全线贯通。针对此问题提出了一种光纤、中压载波混合对等通信技术,在光缆难敷设段以10 kV电力线路作为通信介质,并从对等通信机制、关键载波通信节点布置、数据通信优先级三方面分析对等载波通信的可行性。以单环网供电网架为应用对象,叙述全线路的通信配置应用方案,结果表明智能分布式配网自动化基于文章提出的中压载波对等通信技术可以有效快速隔离配电网故障。The fast fault self-healing technology of distribution network automation mostly depends on optical cable medium communication.In some projects,the full coverage of optical cable can not be implemented because it is very difficult to excavate the optical cable laying path in some sections.To solve this problem,a hybrid peer-to-peer communication technology based on optical fiber and medium voltage carrier is proposed.10 kV power line is used as communication medium in the difficult laying section of optical cable.The feasibility of peer-to-peer carrier communication is analyzed from three aspects of peer-to-peer communication mechanism,communication structure and data communication priority.Taking powernetwork of single ring as the application object,the application scheme of communication configuration is described in the whole line.The distribution network faults can be isolated by using this communication schemeeffectively.
