DUTAN, Paúl  e  MORALES, John. Sensitivity analysis for the determination of characteristic curves of dead time vs transfer power applied to transmission lines. Revista Técnica energía [online]. 2020, vol.16, n.2, pp.1-8. ISSN 2602-8492.  https://doi.org/10.37116/revistaenergia.v16.n2.2020.346.

For the transmission of large electric power blocks to large lengths, Extra High Voltage systems are a good alternative, where the elements that make up the transmission system must be designed in such a way that they offer high reliability and availability during their operation. In this context, it is necessary to perform a proper single-phase autoreclosure, determining the power transmission capacity and the reclosure dead time in the event of single-phase line-to-ground failure considering a single-phase opening and reclosing scheme and Transient Stability of the system. In this sense, this research proposes a methodology to determine characteristic curves corresponding to dead time vs active power of transfer that guarantee a maximum transfer of active power through the transmission lines, and transient stability due to failure, opening and single-phase reclosing events. These characteristic curves will make it possible to decide, from the point of view of transient stability, the most suitable value for adjusting the single-phase reclosing dead time and the dispatched power of the generation central.
