Abstract
Rekonfigurasi sistem distribusi listrik AC menjadi DC pada TSHD King Arthur III dilakukan guna menurunkan nilai impedansi pada sistem distribusi listrik. Penurunan nilai impedansi akan mempengaruhi nilai tegangan jatuh dan rugi daya yang juga akan menurun. Penurunan nilai tegangan jatuh ini dapat memberikan dampak baik bagi komponen kelistrikan sehingga tidak mudah rusak (awet). Pada penelitian ini, proses rekonfigurasi dilakukan menggunakan software simulator sistem distribusi listrik. Proses dimulai dari merangkai single line diagram baik sebelum rekonfigurasi (distribusi AC) maupun setelah rekonfigurasi (distribusi DC) pada software simulator sistem distribusi listrik yang kemudian dilakukan simulasi aliran daya. Pengambilan data aliran daya sebelum dan sesudah rekonfigurasi diambil dari keempat kondisi kapal yaitu seagoing, maneuvering, dredging dan rest in port/anchorage. Berdasarkan hasil simulasi yang didapat secara keseluruhan dari nilai daya keluaran generator tiap kondisi, pada sistem distribusi DC menghasilkan nilai daya aktif yang lebih besar, daya reaktif yang lebih kecil dan daya semu yang lebih kecil dibandingkan dengan sistem distribusi AC. Nilai rugi daya sistem distribusi listrik DC pada setiap kondisi kapal juga memiliki nilai lebih kecil jika dibandingkan dengan sistem distribusi AC dengan rata-rata penurunan sebesar 1,21 kW dan penurunan terbesar terjadi pada kondisi dredging yaitu sebesar 2,074 kW. Selain itu, nilai tegangan jatuh setelah rekonfigurasi menghasilkan nilai yang lebih kecil dan dibawah standar yang ditentukan oleh IEC yaitu 5%. Melalui keseluruhan hasil yang didapat dari simulasi aliran daya di distribusi DC, maka dapat disimpulkan bahwa proses rekonfigurasi ini dapat menguntungkan sistem distribusi listrik TSHD King Arthur III karena dapat menghasilkan sistem distribusi yang jauh lebih efisien dibandingkan dengan distribusi AC.

The reconfiguration of the AC to DC power distribution system in the TSHD King Arthur III was done to reduce the impedance value of the electrical distribution system. Decreasing the impedance value will affect the voltage drop value, and the power loss will also decrease. This decrease in the voltage drop value can have a good impact on electrical components so that they are not easily damaged (durable). In this study, the reconfiguration process was carried out using electrical distribution system simulator software. The process starts by assembling a single line diagram both before reconfiguration (AC distribution) and after reconfiguration (DC distribution) in the electrical distribution system simulator software, which is then simulated for load flow. The load flow data before and after reconfiguration were taken from the four-ship conditions: seagoing, maneuvering, dredging, and rest in port/anchorage. Based on the simulation results obtained from each condition's generator output power value, the DC distribution system produces a larger active power value, smaller reactive power, and smaller apparent power than the AC distribution system. The power loss value of the DC power distribution system in each condition of the ship also has a smaller value when compared to the AC distribution system with an average decrease of 1.21 kW, and the most significant decrease occurs in dredging condition, which is 2.074 kW. In addition, the voltage drop value after reconfiguration produces a value that is smaller and below the standard determined by the IEC, namely 5%. Through the overall results obtained from the simulation of load flow in DC distribution, it can be concluded that this reconfiguration process can benefit the TSHD King Arthur III electricity distribution system because it can produce a distribution system that is much more efficient than AC distribution.
