【摘要】 简要回顾了微机保护的发展历程,介绍了微机保护装置开发手段的现状,通过讨论得出了微机保护装置的软件开发手段对其性能有着决定性影响的结论;进一步对常规微机线路保护装置开发方法的局限性进行分析,提出了一种基于图形化语言进行保护装置开发的方法;通过一个基于目前使用较为普遍的VISIO通用绘图软件和MS3专用工具软件相结合的微机保护软件开发应用实例,说明了使用图形化语言进行高可靠性微机线路保护装置开发的可行性和优势。更多还原

【Abstract】 This paper reviewed the development process of the microcomputer-based protection,and intro- duced its status in quo.Through disscussion,the author concluded that soft development methods of the micro- computer-based protection had a decisive influnce on its performance.Furthermore,the limitation of its develop- ment methods were analyzed,and a kind of development method based on graphical programming language were proposed.This paper developed the software of microcomputer based protection by using VISIO general graphics software and MSS special-purpose tool software,which explained the feasibility and superiority of microcomputer -based line protection by using graphical programming language.更多还原
