CIM-based fault detection analysis of distribution system

Fault detection in distribution system, is one of the most attractive features of smart grid, and an important application in intelligent monitoring and outage management tasks used for realization of self-healing networks. This raises a need for an optimal solution that is able to determine the best result using the knowledge about network parameters, current topology of the network and type of data and algorithms that maybe used to calculate the fault detection. However, the data gathered from various intelligent electronic devices (IEDs) installed throughout the power system, it is necessary to build fault information model platform system in the dispatch center, and follow the international standard IEC61970 and IEC61968. On the basis of the fault information model, this paper introduce the depth-first search method to track the path of power supply (that is the upstream areas) and downstream areas, locate the fault zone through the fault flag, and ensure switch is closed from the side of the electric power source. Finally, this paper presents a practical electrical connection diagram to validate this method described in this paper. The result shows that this method can diagnose the fault zone quickly and accurately.
