FAULT LOCATION IN A NON-HOMOGENEOUS ELECTRIC POWER LINE

摘要

Fault location on a non-homogeneous electric power line that includes aplurality ofsections by determining a section in which negative-sequence voltage magnitudeprofilescalculated from each terminal of the power line intersect. The fault locationmay determinethe faulted section and determine the location of the fault within the faultedsection. Todetermine the fault location, the negative-sequence voltage magnitude profilesmay becalculated from measurements taken at each terminal of the power line andcompared todetermine a point where the profiles intersect. The profiles may be calculatedusing powerline properties and measurements from each terminal.
