The processions of Fault Locating Fault Isolating and Restoration for Distribution are studied in this paper. The Feeder net model for Distribution Automation is built based on the Nod information matrix and the Line information matrix,and the nods represent the switches and the fault indicator in the distribution net. The method of fault Locating offered by this paper called line fault probability method,which locates fault by calculating the fault probability of line in the net. This paper also provides a method called Volts D.C. for restoration and offers the regulation of restoration. Finally,the design and development of this fault process software is described including the Multi-Fault process.
