Paper Title:
A New Practical Fault Location Algorithm for Two-Terminal Transmission Lines
  Abstract

A new practical fault location algorithm using two-terminal electrical quantities is presented in this article, which takes into account the distributed parameter line model. The analytical expression of algorithm derives from Three-Phase decoupling. First, an analytical synchronization of the unsynchronized measurements is performed with use of the determined synchronization operator and the non-synchronizing angle is calculated with the two-terminal pre-fault electrical quantities. Then, the real-time transmission line parameters are calculated using two-terminal non-synchronized electrical quantities and the non-synchronizing angle. The algorithm overcomes the drawbacks of the traditional fault location algorithms, which does not exist the pseudo-root problem. Besides, it has the advantages of simple, practical, litter computation, no need to search and iterative and robustness. The algorithm has not influenced by fault types, the transition resistance and other factors. At last the developed fault location algorithm is tested using signals of ATP-EMTP versatile simulations of faults on a transmission line.
