Fault Location and Diagnosis Algorithms for Radial Distribution Systems

In this paper, a fault location and diagnosis algorithm is proposed. The proposed scheme first identifies fault locations using an iterative estimation of load and fault current at each line section. Then an actual location is identified applying the current pattern matching rules. If necessary, com...

Summary:In this paper, a fault location and diagnosis algorithm is proposed. The proposed scheme first identifies fault locations using an iterative estimation of load and fault current at each line section. Then an actual location is identified applying the current pattern matching rules. If necessary, comparison of the interrupted load with the actual load follows and generates the final diagnosis decision. Effect of load uncertainty and fault resistance has been carefully investigated through simulation results, that turns out tobe very satisfactory.
