智能变电站过程层交换机设计及实现

Design and Implementation of Smart Substation Process Layer Switch

从智能变电站过程层网络传输报文的特点出发,对交换机的传输带宽、存储转发延时、强电磁干扰下的零丢包、采样同步、流量控制、配置管理等方面进行需求分析,提出了一种适用于智能变电站过程层网络交换机的整体研制方案,并对交换机的测试情况和试点运行情况进行了分析介绍。

Based on the smart substation process layer according to the characteristics of the network transmission message, this paper analyzes the requirements of the switch’s transmission bandwidth,storage and forwarding delay,zero loss packet under the strong electromagnetic interference, sampling synchronization, flow control, configuration management and so on. A method is presented for the smart substation process layer network switches the overall development scheme, and the switch test and pilot operation were introduced and analyzed.
