Optimal Coordination of Overcurrent Directional and Distance Relays in Meshed Networks Using Genetic Algorithm
(2015-09-01)
Protection of transmission lines is essential to ensure a correct operation of power systems. In this paper a pilot protection scheme, known as permissive overreaching transfer trip, is used. This structure combine two ...
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 ...
Procedimentos para comissionamento de relés de sobrecorrente
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2018-12-14)
During the operation of the electrical power system (SEP), there are often protection failures
that can result in shutdowns in the power supply, causing a reduction in quality of service. This
is not common, but it happens ...
Efficient coordination of ROCOF and frequency relays for distributed generation protection by using the application region
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2006)
Implementation of transfer trip schemes in numerical overcurrent relays.
(2011-10-13)
Numerical protection devices are much more than just relays. Actually they are small computers with protective functions complemented with others like control, metering, logic, logging and communication. These functions ...
Characteristics of vector surge relays for distributed synchronous generator protection
(Elsevier Science SaLausanneSuíça, 2007)
New methodology for evaluation of non-pilot relay distance protection

A nonlinear binary programming model for fault section estimation in electric power systems
(2017-07-01)
This paper proposes a method to solve the fault section estimation (FSE) problem in power systems by developing a nonlinear binary programming model using the AMPL mathematical programming language. This model is developed ...
