| 摘 要： | 在研究变电站通信网络层次结构及其数据流特点的基础上,根据变电站继电保护数据流的传输实时性要求高的特点,利用OPNET网络仿真软件对变电站对间隔层继电保护设备和变电站层本地监控之间的通信进行了建模。通过对周期性数据流、随机性数据流和突发性数据流三种数据流仿真,研究了变电站通信网络实时性性能。通过仿真分析得出了影响端到端实时性的因素,并分别具体的研究了它们对变电站通信系统实时性性能的影响。

| Abstract: | Based on the study of the structure of communication network and the characteristics of data flow in substation,OPNET network simulation software was used in Substation-level network modeling.Through the emulation of periodic data flow,random data flow and burst data flow,the real-time performance of substation was researched deeply.The main factors of impacting the real-time property of end to end were obtained by simulation,and specific studies were made to reveal the influence of each of the factors to real-time performance of substation communication system. |
