变电站综合自动化系统微机通讯单元的设计

Design of Microcomputer Communication Module for the Integrated Automatic Substation

简要介绍了变电站综合自动化系统中通讯网络的硬件组成、结构特点,以及软件实现方法。为了满足变电站保护的实时性要求,系统采用保护控制单元和通讯监控单元两个CPU协同工作,用串行通讯方法实现两CPU之间的数据传输。保护装置通过以太网连接到变电站网络,以实现高速数据传输。

This paper briefly introduces the hardware composition,structure characteristics and software implement of the communication network which belongs to the integrated automatic substation.In order to meet the real-time request of substation protection,dual CPU corporate in the protect-control module and communication-monitor module,serial communication is adopted to transfer the data between the CPUs.The protector and substation system are connected by the Ethetnet for high-speed data transfer.
