摘　　要：短路电流值是供电系统设计和改造中选择电气设备和进行短路保护装置整定、校验过流保护装置灵敏度的重要依据,图表法是目前煤矿井下供电系统中短路电流值获取的主要方法,但其自身的局限性又大大限制了其应用。针对这种情况开发的"矿井供电系统短路电流Id-l图表生成及动画演示程序",使得Id-l图表的生成十分快捷、灵活、高效,让图表法更为实用,适用性大大拓展。Short--circuit current value is the important basis for selecting electrical equipment, setting short-- circuit protection device and checking the sensitivity of over--current protection devices in design and transfor- mation of power system. The diagram method is the current main method of obtaining the short--circuit current value in coal mine power system, whose limitations greatly limits its application. The paper introduces the development of ＂mine power system short--circuit current Id--1 diagram generation and animation program＂, which makes the Id--1 diagram generation fast, flexible and efficient, the diagram method more practical with expanded applicability.
