Determining the Fault Position in the Power System

This paper describes the determination of the fault location in the power system. This problem is solved in two steps: by determining the line on which the fault occurred using the classification algorithm of the decision tree and determining the fault location on the line by linear regression. In the first step, the decision tree algorithm is used to classify the short circuit and to determine the faulted line based on the information about the residual voltages (voltage dips) on the buses due to the occurrence of a short circuit. In the second step, linear regression is used to find the fault location on the faulted line. The algorithm is tested using the 39-bus IEEE test system.
