摘　　要：文中介绍了配电线路微机保护装置软件系统的总体结构及各功能模块的算法流程图。该系统能够完成线路的单相接地短路保护以及相间短路的电流速断保护和反时限过电流保护;并能够实现单相接地时线路故障点和故障类型的自动判断,便于线路的检修维护。该系统的应用将会大大提高广大城乡电网和工业企业配电网的保护水平。In this paper, distribution line microcomputer protection software system main structure and the function of its every module are introduced and the flow charts is designed, too. This system has the functions of phase to earth short protection, phase to phase short current instantaneous protection and inverse time current protection. The system can distinguish the fault position and fault type of phase to earth short automatically and this is convenient to distribution line maintenance. Its application will improve distribution line protection.
