【摘要】 本文提出了一种集中式双系统配置的ｌｌ０ｋＶ变电站微机保护与监控系统方案。该系统硬件采用工业控制机（主机）与ＰＣ３８６（辅机）相结合；软件编程语言为８０８８宏汇编和Ｃ语言；双系统管理单元采用可编程序控制器。该系统已于１９９４年在山东海阳１１０ｋＶ城阳变电站投入运行。经过半年的实际运行证明：该系统性能完善、可靠，保护动作准确。更多还原

【Abstract】 A new concentric double system control-ling scheme for ll0 kV substation that includes pro-tection,supervisory and measurement is presented inthis paper. Industrial real-time control computer andPC386 are adopted, The software is programmed byMicro-Assembly and C-Language.The double systemis monltored by a programmable controller. The Prac-tical experiences of the system for half a year indicatethat the svstem is reliable and the protection behavioris effective.更多还原
