Resumen

THOMAS, R. et al. Recloser based energy exposure assessment of a distribution network. J. energy South. Afr. [online]. 2019, vol.30, n.4, pp.41-50. ISSN 2413-3051.  http://dx.doi.org/10.17159/2413-3051/2019/v30i4a2486.

The optimised placement of reclosers on a distribution network is known to improve the reliability of a power system. Furthermore, the protection settings on distribution systems rely heavily on the number and placement of such reclosers. This study examined the effect of using protection settings methodology with the placement of reclosers to ameliorate the damage sustained during faults on a distribution network. The aim of the study was to determine whether this 'damage control factor' should be a future consideration for recloser placement. It has been found that the determination of the number and placement of reclosers, which are the function of the energy exposure of feeder, helped to optimise the operation and reliability of a distribution network. This could benefit both energy users and energy suppliers, who often face different challenges during the fault levels on the network.Highlights • Assesses energy exposure to avoid damage to the system during a given fault conditions. • Develops the effect of using protection settings methodology with the number and replacement placement of reclosers. • Alleviate damage sustained during faults into an electrical distribution network. • Assesses an optimal relationship between the number and replacement of reclosers in the network and the energy exposure of the feeder.

Palabras clave : damage factor; electricity grid; fault condition; protection settings.
