Faults in a distribution network cause partial or complete blackout of feeder. It is necessary to supply the power to the remaining healthy part of a feeder after isolation of faulty section. This can be achieved by proper opening and closing of tie-line switches (normally open switches) and sectional switches (normally closed switches). With that the topology of a network will change and the losses will be redistributed. In this paper Dijkstra’s algorithm is used as a high speed switching algorithm, which gives information about the status of the switches to restore the supply to all the load points in the event of outage of any line or a transformer/feeder. It also gives the minimum impedance path from source to all the load points. In this paper IEEE standard 16 node distribution test system is considered for a case study. Load flow analysis is carried out using a MATLAB tool.
