Estrategia colaborativa basada en la reactancia de falla y la firma del sistema para la localización de fallas en sistemas de distribución.

A collaborative strategy for fault location in power distribution systems based on the fault impedance and the system signature, and using only single-end measurements, is presented in this paper. This strategy is useful to solve the multiple estimation of the faulted node, which is due to the presence of several laterals in the power system topology. According to the tests performed in a prototype power distribution system, considering single phase faults, phase to phase faults and three phase faults, and also using fault resistances from 0 to 40 Ω, the obtained results show an average absolute error of 5,2% approximately. From the results can be concluded that this proposal is efficient to locate faults in power distribution systems. [ABSTRACT FROM AUTHOR]
