Abstract
A new adaptive numerical algorithm for overhead line protection is presented in this paper. It uses an advanced fault model taking into account the arcing phenomena at the fault location and an efficient parameter estimation technique. A dynamic arc model is included in fault modelling to represent the arc interaction with the transmission system. Performance of the proposed estimation technique is extensively verified at different arc model parameters. The algorithm is derived in the time domain and it is based on synchronized acquisition of currents and voltages at both line terminals. It is tested through computer-based simulations of a line connecting two active networks. ©2007 IEEE.
