配电网故障定位中通信系统协议设置

摘要

In this paper,the wireless ad hoc network is used to achieve distribution network fault detection.Real-time online monitoring of the distribution network is achieved by installing wireless nodes to distribution networks.This paper simulated protocol of wireless ad hoc networks using the NS2 software to select the protocol for this system to improve system performance.A Comparison is made between end-to-end delay and packet delivery ratio under different number of nodes and the residence time of three protocols,namely DSDV,DSR,and AODV.Their throughputs under the basic access mechanism and RTS/CTS mechanism are also compared.Finally,the AODV protocol is chosen and the frame size threshold is set.%采用无线自组织网络实现配电网故障检测。通过在配电网上安装无线节点,架构无线网络实现对配电网实时在线监测。文中主要利用NS2软件对无线自组织网络的协议进行了仿真分析,目的是选择适用于该系统的协议,以提高系统的性能。对DSDV、DSR、AODV的3种协议在节点数和停留时间不同情况下的端到端延时、分组投递率进行了比较,并且对基本接入机制和RTS/CTS机制下的吞吐量进行了比较,最终选择AODV协议并设置帧长门限值。
