Fault diagnosis in deregulated distribution systems using an artificial neural network

With the arrival of deregulation, the traditional vertically integrated power systems are faced with some challenging uncertainties. Many uncertainties concern the control, operation and protection of distribution systems in a competitive electric market especially with the introduction of deregulation. This paper presents the problems in fault diagnosis of high impedance faults (HIF) in deregulated distribution systems and a proposed solution based on artificial neutral networks (ANN).
