摘要
本文对广域继电保护的通信系统基本模式进行了研究,利用通信仿真软件Network Simulator对通信网络性能进行仿真与分析。以鄂东地区220kV局部电网为例,对不同网络环境、多次路由转发模式下的网络通信仿真,将其网络通信延时与掉包率进行比较分析,验证了基于SDH广域通信的可行性。
This paper investigates the basic mode of communication system for wide area protection and also carries out the simulation and analysis for the feasibility of the communication network by using the communication simulation software Network Simulator.Taking the local 220 kV grid at east Hubei Province as an example,we have compared and analyzed the network communication delay and transmission packet loss rate caused by the different net environment and multiple routes switching communication simulation,which confirms the feasibility of the wide area communication based on the SDH.
