摘要:

论述利用无线传感器网络构建线路纵联差动保护应急通信通道的技术方案，在考虑节点数量及其灾变损毁率情况下，提出了基于全网络通信可靠性及成本最优的节点冗余布置方法。并研究AODV路由方式下，节点通信距离、架空线路杆塔档距及转跳次数对通信延时的影响并分析了延时抖动。通过纵联差动保护数字仿真试验表明，基于无线传感器网络构建的保护通道采用节点冗余布置方法进行网络规划，在极端灾变情况下可获得较高的生存性，基本满足纵联差动保护的信息传输需求。

Abstract:

Optical fiber differential protection is widely used as the primary protection of power transmission line, but it may be influenced by extreme natural and man-made hazard which would impair protection performance. This paper discusses a technical scheme of pilot differential protection channel based on wireless sensor network. Taking the number of nodes and failure rates into account, redundancy arrangement of nodes based on reliability of the whole communication network and optimal cost is proposed. Besides, this paper studies the influence of the communication distance, line spans and communication range of nodes on end-to-end time delay under AODV routine. The results of pilot differential digital simulation test shows that emergency protection channel constructed by wireless sensor network which uses redundancy arrangement method to do network panning can achieve strong survivability and meet the need of pilot differential protection under extreme disaster. This work is supported by National High-tech R & D Program of China (863 Program) (No. 2015AA050201).
