【摘要】 介绍一种以ＳＴＤ总线工业控制机为核心的单ＣＰＵ集中式变电站微机保护及监控系统的监控程序、保护程序和自检程序。该系统的程序采用８０８８汇编语言编写，多层模块结构，利用ＣＰＵ内部计时器设置周期性中断，保证继电保护功能的绝对优先；自检程序对工控机进行检查修复和报警。更多还原

【Abstract】 This paper presents a single CPU microcomputer centralized protection and control system for substation. It emphatically describes the supervisory control software, protection software and self checking software design. The STD bus computer as realtime controller is adopted in hardware dispostion. The software is worked out by using 8088 assemble languages. It has the ability of high immunity to interference and reliability.更多还原
