Fault phase selection and fault Identification in weak-infeed side
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 1
Abstract
Traditional low voltage phase selector and sequence current based fault phase selector will not operate satisfactory under weak infeed condition. The study proposes a new method of fault phase selection for transmission lines under weak infeed conditions. The method uses the relative phase angle relationship between negative and zero sequence voltages and superimposed positive and negative voltages to identify the faulty phase under weak infeed condition. The location fault is also determined by using negative sequence components of voltage and current at both ends of the line. The simulation of the system is done with MATLAB and PSCAD.
