Abstract
A phase to ground fault apparent (PGFA) admittance system and method with phase/ground boundaries for detecting electrical power line faults. The PGFA admittance method with phase/ground boundaries is based on measuring the A, B and C phase admittance magnitudes for faulted and non-faulted phases, resulting in greater than zero and near zero, respectively, and using the phase/ground boundaries to distinguish between the LL and LLG electrical faults. The PGFA admittance method with phase/ground boundaries is based on a pre-setting of values by using the zero, positive and negative sequences of power line sections, to determine phase and ground boundaries. The PGFA admittance algorithm with phase/ground boundaries was built with MATLAB/Simulink software and tested and evaluated with a confusion matrix. The measured and predicted values matched in more than 90% of the tests, and the PGFA admittance method presented an accuracy of 94.3% and a precision of 100%.
