摘要: 光纤纵联差动保护被普遍用作输电线路的主保护,但在极端灾变情况下,可能因光纤通道中断导致保护失效。为了重构灾变后的紧急通信通道,提出利用无线传感器网络结合电力设施监测构建线路纵联差动保护紧急通信通道的技术方案。介绍了WSN的网络结构和特点,分析了WSN在极端灾变情况下相对于传统继电保护通信方式的优越性,探讨了节点的布置方式和能量供给,并对WSN应用于通信通道重构时的可靠性和时延等关键技术进行了阐述,最后设计了一种适用于此紧急通信通道的路由协议,保证了保护信息的可靠传输。

Abstract: Optical fiber differential protection is widely used as the primary protection of power transmission line, but it may fail influenced by extreme natural and man-made hazard which would impair protection performance. In order to reconstruct emergency communication channel after hazard, combining with power facilities monitoring system, this paper presents a technical scheme of pilot differential protection channel based on wireless sensor network,introduces the network structure and characteristics of wireless sensor network(WSN), analyzes the superiority of communication mode on WSN for protection of traditional mode . In addition, the paper researches the arrangement mode and power supply of sensors, discusses the key technology including network reliability and time delay , and designs a routing protocol applied to emergency communication channel to ensure reliable transition of protection information.

Key words: wireless sensor network(WSN), emergency communication channel, pilot differential protection, routing protocol, reliability
