Abstract

PT. Aneka Tambang (PT. ANTAM) merupakan badan usaha milik negara (BUMN) yang bergerak dalam bidang eksplorasi, pertambangan, pengolahan serta pemasaran dari sumber daya mineral. PT. Antam memiliki pembangkitan sebesar 10x5805 kW dan 8x17076 kW. Kemudian ditambahkan generator sebesar 2x31875 kW. Namun pada konfigurasi sistem yang baru generator sebesar 10x5805 kW tidak dioperasikan dan karena telah digantikan dengan pembangkit tenaga uap sebesar 2x31875 kW sehingga menyebabkan perubahan konfigurasi sistem kelistrikn. Dalam tugas akhir ini akan dilakukan studi kestabilan transien dari sistem kelistrikan PT. Aneka Tambang. Beberapa gangguan transien yang akan dijadikan studi kasus dalam tugas akhir ini adalah gangguan generator outage, hubung singkat dan motor starting. Ketiga jenis gangguan tersebut akan memberikan gambaran mengenai kehandalan sistem kelistrikan terhadap gangguan transien. Tugas akhir ini memfokuskan pada mekanisme load shedding sebagai solusi terhadap berbagai jenis gangguan yang digunakan sebagai studi kasus. Program yang digunakan untuk melakukan analisis adalah ETAP 11. Hasil simulasi yang didapatkan pada tugas akhir ini akan dianalisis dan kemudian baru melakukan perancangan mekanisme load shedding yang sesuai. Terdapat dua jenis load shedding yang digunakan yaitu frekuensi dan status. Apabila dibandingkan kedua jenis load shedding ini maka jenis load shedding status dapat membuat sistem lebih cepat stabil daripada load shedding frekuensi. Kasus hubung singkat pada bus 00AHC20 (30 kV) memerlukan skema load shedding karena terlepasnya generator STG-2G pada saat terjadi hubung singkat. ===================================================================================================== PT . Aneka Tambang (PT. ANTAM) is one of State Owned Enterprise ( BUMN ) which engaged in the field of mining, exploration and mineral marketing. PT.ANTAM formerly possessing power generation of 10x5805 kw and 8x17076 kw and currently has been added a new generator of 2x31875 kw . But in this configuration the generator of 10x5805 kw that is the power generators diesel generators to be replaced with steam power of 2x31875 kw thus causing changes in system configuration . So in this study will be held a transient stability analysis of electrical system of PT. Aneka tambang . A transient stability disturbance that will be used as a study cases are generator outage , short circuit and motor starting .These three types of the disturbance will give an overview of performance of electric system against a transient disturbance. The end of it focuses duty is to give the mechanism of load shedding as a solutions to various kinds of disturbance that used as case studies .A program used to do the analysis is ETAP 11 . The Simulation results obtained on this final project will be analyzed and then doing the design mechanism of load shedding is appropriate. There are two types of load shedding used IE frequency and status. When compared both types of load shedding the type of load shedding status can make a faster system stable than the frequency load shedding. Short Circuit on bus 00AHC20 ( 30 kv ) requires load shedding scheme because the generator STG-2G was forcibly off due to bus fault.
