集中式变电站微机保护与监控系统的设计

Research of a Centralized Microcomputer Protection and Supervisory & Control System for a Substation

针对某供电局１１０ｋＶ变电站的实际情况和具体要求，完成了一种以ＳＴＤ总线工业控制机为核心的集中式变电站微机保护及监控系统的软件设计和硬件设计。软件采用８０８６汇编语言编写，采用多层模块化结构；硬件采用ＳＴＤ５０００总线Ｖ４０Ⅱ系列工业控制机为主机，具有模板化、小型化的开放式结构和可用组合式设计方法的特点。

This paper briefly describes a microcomputer protection and supervisory control system for a substation using an STD bus computer. The software is programmed in 8086 assemble languages, microcomputerbased on an STD bus is used as the hardware of this system, it has the high ability of immunity to interferenceand is very reliable. Now this system has worked in 110 kV Zhaowang Substation for more than one year.
