چکیده

This study presents a fault location algorithm (FLA) for series compensated transmission lines (SCLs). It is established based on synchronised voltages sampling and Thevenin impedance estimation from both ends of SCL. The method is based on the use of phasor measurement units technology which is aimed to be independent of current measurements. This method includes two subroutines for the faults located on the right-hand and left-hand sides of series capacitor (SC). Lumped modelling is considered for SCL with SC equipped with metal–oxide varistor (MOV) arrester. The non-linear behaviour of SC-MOV system is investigated in the analysis. The proposed current independent FLA has been thoroughly tested using signals taken from simulations. According to the results, the percentage errors for the fault distances estimation are in proper ranges.
