Abstract

Permasalahan ketersediaan dan keandalan sistem tenaga pada kapal selam mini menjadi tantangan penting dalam perancangan sistem kelistrikan, khususnya saat kapal beroperasi penuh di bawah permukaan air tanpa sumber daya eksternal. Tugas Akhir ini dilakukan untuk menganalisis kebutuhan daya total dan menentukan pemilihan komponen utama seperti baterai, kabel, busbar, serta proteksi kelistrikan yang sesuai standar kelautan. Tujuan dari penelitian ini adalah untuk memperoleh desain sistem distribusi daya yang aman, andal, dan efisien pada kondisi operasi terberat. Metode yang digunakan mencakup simulasi analisis aliran daya dan pembebanan menggunakan perangkat lunak ETAP, serta pendekatan teknis terhadap kapasitas hantar arus kabel, pemilihan busbar, dan proteksi arus lebih dengan mengacu pada PUIL 2011, BKI Rules 2015, dan standar IEC 60947 dan IEC 60902. Penentuan kapasitas baterai didasarkan pada akumulasi beban dari seluruh skenario operasional yang telah dimodelkan. Hasil penelitian menunjukkan bahwa total energi yang dibutuhkan selama kapal beroperasi di bawah permukaan laut adalah sebesar 667,23 kWh, sehingga diperlukan 103 unit baterai dengan kapasitas 200 Ah. Kabel ditentukan berdasarkan arus nominal dikalikan faktor koreksi 1,25, dengan ukuran terbesar 25 mm² pada jalur propulsi. Pemilihan busbar dan proteksi menggunakan MCB, MCCB, dan ELCB disesuaikan dengan karakteristik tiap beban dan mempertimbangkan lingkungan laut yang korosif dan tertutup. Selain itu, hasil simulasi load flow menunjukkan bahwa seluruh titik distribusi berada dalam batas toleransi tegangan ±5% dari nilai nominal sistem DC, sesuai standar IEEE 1159-1995, yang menegaskan bahwa rancangan sistem telah memenuhi kriteria performa tegangan yang stabil dan andal.

The availability and reliability of the power system on a mini-submarine pose significant challenges in electrical system design, particularly when the vessel operates fully underwater without external power sources. This final project analyzes total power requirements and determines the selection of key components, such as batteries, cables, busbars, and electrical protection, in accordance with marine standards. The objective of this research is to design a safe, reliable, and efficient power distribution system under the harshest operating conditions. The methods used include power flow and loading analysis simulations using ETAP software, as well as a technical approach to cable current-carrying capacity, busbar selection, and overcurrent protection, referring to PUIL 2011, BKI Rules 2015, and IEC 60947 and IEC 60902 standards. Battery capacity determination is based on the accumulated load from all modeled operational scenarios.The results indicate that the total energy required during submerged operations is 667.23 kWh, requiring 103 batteries with a capacity of 200 Ah. The cable is determined based on the nominal current multiplied by a correction factor of 1.25, with the largest size of 25 mm² on the propulsion line. The selection of busbars and protection using MCB, MCCB, and ELCB is adjusted to the characteristics of each load and takes into account the corrosive and enclosed marine environment. In addition, the results of the load flow simulation show that all distribution points are within the voltage tolerance limit of ±5% of the nominal value of the DC system, according to the IEEE 1159-1995 standard, which confirms that the system design has met the criteria for stable and reliable voltage performance
