Location of single line-to-ground faults on distribution feeders using voltage measurements
This paper proposes a dedicated algorithm for lation of single line-to-ground faults in distribution systems. The proposed algorithm uses voltage and current phasors measured at the substation level, voltage magnitudes ...
PMUs optimized allocation using a tabu search algorithm for fault location in electric power distribution system
Phasor Measurement Units (PMUs) optimized allocation allows control, monitoring and accurate operation of electric power distribution systems, improving reliability and service quality. Good quality and considerable results ...
Extended Fault-Location Formulation for Power Distribution Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
In this paper, an extended impedance-based fault-location formulation for generalized distribution systems is presented. The majority of distribution feeders are characterized by having several laterals, nonsymmetrical ...
Optimal phasor measurement units placement for fault location on overhead electric power distribution feeders
This paper proposes a new approach for optimal phasor measurement units placement for fault location on electric power distribution systems using Greedy Randomized Adaptive Search Procedure metaheuristic and Monte Carlo ...
Investigating effects of neutral wire and grounding in distribution systems with faults
In some applications like fault analysis, fault location, power quality studies, safety analysis, loss analysis, etc., knowing the neutral wire and ground currents and voltages could be of particular interest. In order to ...
Phase Distance Relaying With Fault Resistance Compensation for Unbalanced Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
This letter presents an extension of an existing ground distance relay algorithm to include phase distance relays. The algorithm uses a fault resistance estimation process in the phase domain, improving efficiency in the ...
