摘　　要：针对我国现行变电站网络通信系统中存在的不足之处,提出了一种新型的基于IEC61850通信协议和嵌入式以太网技术的变电站网络通信系统结构。介绍了IEC61850通信协议的主要特点,提出了以太网和LonWorks现场总线相结合的以太网应用模式,给出了IED(Intelligent Electronic Device)的硬件结构图。实验结果表明,与传统变电站网络通信系统相比,该新型变电站网络通信系统的网络带宽大大增加了,能够实现变电站的间隔层至远动控制中心的无缝通信连接,并且易于和PC机和广域网相连,具有很好的应用前景。To deal with the weakness of current substation network communication system of our country, presented a new architecture of substation network communication system based on IEC61850 communication protocol and embedded Ethemet technique. The main characteristics of IEC61850 communication protocol were introduced, Presented the application mode of Ethernet which combined Ethernet with LonWorks field bus and put forward the hardware framework of IED（ Intelligent Electronic Device）. Experimental results show that compared with traditional substation network communication system, the bandwidth of this new system increases greatly, and it can realize the seamless communication from the bay layers of substation to telecontrol centers and is ease to connect to PCs and WAN, so it has a good applying outlook.
