Abstract

Dalam Sistem Tenaga Listrik dapat terjadi gangguan gangguan pada distribusi ataupun merusak komponen dari sistem tersebut. Gangguan tersebut dapat terjadi dimanapun termasuk pada sistem Distributed Generation. Distributed generation, yaitu membuat pembangkit tersebar yang nantinya akan tersambung dengan jaringan distribusi , dengan kapasitas yang relatif kecil ( kurang dari 5 MW) gangguan yang paling terjadi adalah gangguan Short Circuit, cara untuk mengamankan gangguan tersebut pada jaringan distribusi biasanya menggunakan recloser, selian recloser ada sistem pengamanan lain untuk membantu kinerjanya yaitu fuse. Koordinasi Fuse dan recloser sangat penting pada jaringan distribusi untuk mengamankan gangguan short circuit yang ada. Pada jaringan distribusi dengan penambahan DG, arah short circuit dapat terjadi pada arah forward dan reverse, untuk itu salah satu recloser yang dipilih ada dual setting diferential recloser (DSDR). Arah forward akan disetting berbeda dengan arah reverse dikarenakan sumber short circuit reverse yaitu DG tidak akan mengirim arus gangguan yang sangat besar. Pada percobaan IEEE 13 node test feeder bus 645 didapatkan arus short circuit maximal sebesar 1460 A dan waktu fuse untuk trip adalah 0.14 s dan recloser 1 akan terjadi fast operation pada 0.052 s dan recloser 2 akan terjadi fast operation pada 0.043 s. Pada percobaan IEEE 34 node test feeder bus 810 didapatkan arus short circuit maximal sebesar 741 A dan waktu fuse untuk trip adalah 0.122 s dan recloser 1 akan terjadi fast operation pada 0.041 s dan recloser 2 akan terjadi fast operation pada 0.106 s.

In the Electric Power System, disturbances can occur in the distribution or damage the components of the system. These disturbances can occur anywhere including the Distributed Generation system. Distributed generation, which is to create a scattered generator that will be connected to the distribution network, with a relatively small capacity (less than 5 MW) the most common disturbance is Short Circuit disturbance, the way to secure these disturbances in the distribution network usually uses a recloser, besides the recloser there is another security system to help its performance, namely the fuse. Fuse and recloser coordination is very important in distribution networks to secure existing short circuit disturbances. In distribution networks with the addition of DG, the direction of the short circuit can occur in the forward and reverse directions, for that one of the selected reclosers is a dual setting diferential recloser (DSDR). The forward direction will be set differently from the reverse direction because the reverse short circuit source, namely DG, will not send a very large fault current. In the IEEE 13 node test feeder bus 645 experiment, the maximum short circuit current is 1460 A and the fuse time to trip is 0.14 s and recloser 1 will occur fast operation at 0.052 s and recloser 2 will occur fast operation at 0.043 s. In the IEEE 34 node test feeder bus 810 experiment, the maximum short circuit current is 741 A and the fuse time to trip is 0.122 s and recloser 1 will occur fast operation at 0.052 s.
