Accurate fault location method based on local measurements and remote currents

摘要

The present disclosure relates to a computationally efficient technique for determining a location of a fault on a power line using local measurements and remote current measurements. For example, a method may include receiving one or more local measurements of a power line. The method includes receiving a signal indicating one or more remote current measurements of the power line. The method includes determining a location of a fault on the power line based on a fault voltage multiplied by a conjugate of a compensated differential current. The method includes providing the location of the fault.
