摘　　要：微机保护装置的保护功能是由软件实现的,因此用户就有将同一硬件配置成具有不同保护功能的可能性,可以通过程序设计工具软件增减功能和改变逻辑,以实现保护功能的现场重置,这在常规保护装置中是不可能实现的;讨论了实现用户进行微机线路保护装置保护功能现场重置的优势;简要介绍了目前国际上对这一技术手段的应用情况,并针对目前国内微机保护的开发和使用现状,分析了实现这一功能需要解决的技术问题;介绍了一种基于并行处理的图形化编程方法,并对其可信赖性进行了讨论。The protective function of microcomputer protective relay is realized by softwares, so users have the possibility of disposing different protective functions on identical useful harduares and they may fluctuate the functions and change logic through tool softwares of programming so as to realize protective function reconfiguration in the field, which is impossible in the conventional protective relay. This article discusses the advantages of users＇ reconfiguration of protective relay function of microcomputer line, briefly introduces the present international application of this technological means, briefly analyzes the technical problems that need to be soloved in realizing this function based on its domestic development and application,introduces a kind of graphical programming method based on parallel processing and discusses its reliability.
