This invention relates to methods for detection and experiment for distribution net automation system. When in experiment distribution, net circuit fault points are analoged on a single line picture of a primary station computer system sending down current values with time scale in a way of loading a software then a sub system transfers it to FTU analyzing the time scale sent by the primary station and sending up fault virtual distance information at the said time point and simulating misalignment on a related gate out switch of the electric substation side, the substation computer system starts DA process and the master system examines if DA process is correct. 本发明涉及一种配网自动化系统的检测、试验方法，特别是一种配网自动化故障隔离和网络重构系统的整组试验方法。试验时，在主站计算机系统的单线图上模拟配网线路故障点，然后以加载软件的方式通过主站系统下发带时标的电流值，再由子站系统传递给所涉及的FTU，FTU解释主站系统下发的时标，并在此时间点上上传故障虚遥信，同时，在变电站侧相应的出口开关上使其模拟重合不成现象，由子站计算机系统在收集到这些条件后启动DA过程，在主站计算机系统上观察、验证DA过程的是否正确。本发明试验过程方便、耗时短、试验成本低，并可使进行DA整组试验所受限制较少，可作为配网自动化系统DA整组试验的通用试验方法。
