Abstract

This article presents a general approach for locating any type of short circuit faults on a double-circuit transmission line. By making use of the bus impedance matrix technique, voltage measurements at one or two buses are utilized as inputs, which may be distant from the faulted section. The bus impedance matrix of each sequence network with addition of a fictitious bus at the fault point can be constructed as a function of fault location by drawing on network analysis. Fault location can then be obtained based on bus impedance matrix and boundary conditions of different fault types. It is assumed that the network data are available. Quite accurate results have been achieved based on simulation studies.
