基于STD总线的变电站微机保护及监控硬件系统

A RESEARCH ON THE HARDWARE SYSTEM OF MICROCOMPUTER PROTECTION& SUPERVISORY CONTROL SYSTEM IN SUBSTATIONBY USING THE STD BUS COMPUTER

介绍一种以ＳＴＤ总线工控机为核心的单ＣＰＵ集中式变电站微机保护及监控系统的硬件结构和抗干扰、可靠性措施。该系统具有继电保护、测量监视、操作控制、中央信号、接地选线和记录打印等功能，已成功地应用于３０多个３５ｋＶ变电站。

This paper briefly describes a microcomputer protection & supervisory control systemfor substation by using the STD bus computer. After describing the scheme of protection andsupervisory system. a new concentrated architecture is put forward. This system can be used in35 kV substations.
