Özet

This paper presents a new setting-free approach to synchronization of two-end current and voltage unsynchronized measurements. Authors propose new non-iterative algorithm processing three-phase currents and voltages measured under normal steady state load condition of overhead line. Using such synchronization the line parameters can be estimated and then precise fault location can be performed. The presented algorithm has been tested with ATP-EMTP software by generating great number of simulations with various sets of line parameters proving its usefulness for overhead lines up to 200km length.
