ANALISIS KOORDINASI RECLOSER DAN SECTIONALIZER PADA JARINGAN DISTRIBUSI 20 KV DI PT. PLN (PERSERO)

Abstract

The aim of this research is needed a security system that is appropriate to the type of disturbance that occurs properly, efficiently and reliably. This research was conducted at the RRI PT feeder. PLN (Persero) ULP Sungguminasa to determine the coordination of protection equipment at the feeder. The analysis was carried out by comparing manual calculations with the ETAP 19.0.1 software simulation and also compared with the MATLAB GUI simulation results. The setting results obtained for the RRI feeder at the 3 phase short circuit current of the cambaya TMS recloser = 0.09 and talia sectionalizer = 0.159. Recloser and sectionalizer coordination is based on the location of the disturbance that occurs. There is interference between the recloser and sectionalizer, so the only thing that works on this network is the recloser. If interference occurs after the sectionalizer, the recloser will open first. After that the sectionalizer detects the loss of voltage due to the open recloser. Only after that will the sectionalizer work (open).
