摘　　要：过程层网络的通信性能对智能变电站的安全稳定运行起着关键的决定作用。而通信以太网络的不透明、不可视,使过程层网络通信过程不可控,这成为智能变电站发展的瓶颈。以过程层网络报文特性为切入点,对典型智能变电站——琴韵变的过程层网络报文特征进行分析,进而对过程层网络的通信特性做出研究,指出现有过程层网络通信配置中的一些不足,并给出了改进办法。这在一定程度上使过程层网络变得透明、可控,并对智能变电站的建设工作具有一定的探索性参考意义。The network communication performance of process layer plays a decisive role in the safe and stable operation of intelligent substation. However, the opaque and invisual features of the Ethernet network makes the network communication of process layer uncontrollable, which hinders the development of the intelligent substation. Starting from the message characteristic of process layer network, this paper analyzes the message characteristics of a typical intelligent substation i.e. Qin Yun intelligent substation, then studies the communication characteristics of the process layer, points out the deficiency of the communication configuration, and proposes some improvement methods. It can make the process layer network transparent and controllable to some extent and has a certain exploratory significance on the construction of the intelligent substation.
