Abstract/Summary In this paper we present a novel approach for the study of faults on the transmission network of a power system. This is achieved by deriving an analytical nonlinear model of the power system with the fault signals modelled as inputs. The power system is assumed be to comprised of an 8th order machine, a 3rd order exciter and a 3rd order governor, resulting in a 14th order nonlinear model of the generating unit. This is then connected to an infinite bus through a transmission system. Faults on the transmission system are modelled and incorporated with the generating unit model to construct an overall nonlinear model of the power system. In addition to fault studies, the developed model can also be used for protection, dynamic and transient stability studies.
