Abstract

Penelitian ini bertujuan untuk menganalisis kestabilan transien pada rancangan kapal katamaran full-electric yang mengacu pada standar IEEE. Latar belakang penelitian ini didasarkan pada meningkatnya minat industri maritim untuk beralih dari penggunaan generator ke sumber energi listrik seperti baterai, guna mengurangi emisi dari sistem kelistrikan konvensional. Metode yang digunakan adalah simulasi dengan bantuan perangkat lunak, yang memungkinkan identifikasi serta evaluasi berbagai parameter yang memengaruhi kestabilan transien pada sistem kelistrikan kapal. Tujuan akhir dari simulasi ini adalah memastikan bahwa respon sistem terhadap gangguan tetap berada dalam batas standar IEEE, yaitu deviasi frekuensi ±3% dan deviasi tegangan ±10%. Simulasi dilakukan berdasarkan beberapa studi kasus sesuai dengan kondisi operasi kapal. Hasil simulasi menunjukkan bahwa respon frekuensi pada semua kondisi telah memenuhi standar IEEE, yaitu stabil di angka 100%. Namun, terdapat ketidaksesuaian pada respon tegangan, khususnya pada studi kasus sistem pod saat kapal dalam kondisi sailing. Setelah gangguan dihilangkan, tegangan hanya mencapai 68,61%, jauh di bawah batas bawah standar. Tetapi hasil dari respon tegangan untuk studi kasus yang lain dan dalam kondisi kapal yang lain menunjukkan presentase yang sudah sesuai dengan standar dengan preseentase rata rata diatas 99%. Untuk mengatasi hal tersebut, dilakukan mitigasi dengan meningkatkan kapasitas daya inverter dari 750 kW menjadi 15 MW. Setelah mitigasi, respon tegangan meningkat menjadi 92,38%, yang sudah berada dalam rentang standar IEEE. Oleh karena itu, mitigasi ini dinyatakan berhasil. Penelitian ini diharapkan dapat menjadi referensi bagi pengembangan sistem kelistrikan kapal berbasis baterai yang lebih ramah lingkungan di masa depan.

This study aims to analyze the transient stability of a full-electric catamaran ship design in accordance with IEEE standards. The background of this research is based on the growing interest in the maritime industry to shift from using generators as power sources to electric energy sources such as batteries, in order to reduce emissions from conventional electrical systems. The method used is simulation with the help of software, allowing the identification and evaluation of various parameters that affect the transient stability of the ship's electrical system. The main objective of the simulation is to ensure that the system's response to disturbances remains within the limits set by IEEE standards, namely a frequency deviation of ±3% and a voltage deviation of ±10%. Simulations were conducted based on several case studies reflecting the ship’s operational conditions. The simulation results show that the frequency response under all conditions meets the IEEE standard, maintaining stability at 100%. However, there is a deviation in the voltage response, particularly in the case study involving the pod system during sailing conditions. After the disturbance is cleared, the voltage only reaches 68.61%, which is significantly below the standard threshold. On the other hand, voltage responses in other case studies and under different ship conditions show percentages above 99%, which are within the acceptable standard range. To address the voltage deviation, mitigation was carried out by increasing the inverter power capacity from 750 kW to 15 MW. After this adjustment, the voltage response improved to 92.38%, which falls within the IEEE standard range. Therefore, this mitigation is considered successful. This study is expected to serve as a reference for future research and development of battery-based, environmentally friendly ship electrical systems.
