Pengaruh Level Penetrasi Pembangkit Skala Kecil Tersebar Terhadap Mitigasi Fuse Saluran Udara Tegangan Menengah

Abstract

Fuse dan recloser secara tradisional digunakan untuk mereduksi gangguan pada saluran udara dimana pada feeder utama dipasang recloser dan pada lateral feeder dipasang fuse. Fuse adalah alat proteksi murah dan andal yang akan melebur dalam beberapa siklus akibat suatu arus gangguan yang tinggi. Untuk minimalisasi jumlah fuse yang putus, dilakukan back-up oleh recloser . Pada gangguan temporer, recloser akan mengkliring gangguan yang menjadi prioritas fuse . Skema proteksi ini dikenal sebagai fuse saving operation . Mekanisme koordinasi proteksi ini akan berubah ketika dilakukan integrasi Abstract Fuse and recloser are traditionally used to reduce interference in the airways where the main feeder is installed recloser and the lateral feeder is installed fuse. Fuses are inexpensive and reliable protection devices that will fuse over several cycles due to a high fault current. To minimize the number of broken fuses, a back-up is performed by the recloser. In the case of temporary disturbances, the recloser will clear the disturbance that is the priority of the fuse. This protection scheme is known as fuse saving operation. This protection coordination mechanism will change when the generating unit is integrated into the network. This occurs due to changes in the fault current due to the contribution of the fault current from the generator. The magnitude of the significant change is influenced by the location and capacity of the generating unit. The research objective is to develop an evaluation tool for the fuse mitigation process that is affected by mal coordination due to the location of the generator and the penetration level of the generator. The research methodology was carried out by developing software using MATLAB with the subject of the 34 node IEEE Test network study. The results showed that a low penetration level of 20% only had a small impact on protection coordination and a high penetration level only prevented mal coordination in installations near substations.
