Abstract
Dalam rangka untuk menurunkan nilai impedansi dari sistem distribusi listrik pada kapal maka dilakukan rekonfigurasi system distribusi listrik pada kapal tanker dari AC ke DC. Dengan adanya rekonfigurasi system dari AC ke DC nilai impedansi pada system akan turun karena hanya ada resistansi (R). Sebagai akibat dari nilai impedansi turun maka nilai tegangan jatuh dan rugi daya juga akan turun. Penurunan tegangan jatuh dapat memberikan efek baik seperti komponen listrik akan lebih awet. Proses penelitian dimulai dengan memodelkan single line diagram dari sistem distribusi listrik pada kapal tanker. Pada penelitian ini dilakukan simulasi aliran daya menggunakan software simulasi. Pengambilan data diambil dengan perbandingan antara sistem distribusi bawaan pada kapal tanker yaitu AC dan kemudian dilakukan perubahan atau rekonfigurasi menjadi DC. Pengambilan data diambil pada beberapa kondisi operasi kapal yaitu sailing, leaving-arriving, loading-unloading, dan at port. Berdasarkan hasil simulasi yang didapat, hasil aliran daya tiap bus, hasil simulasi berupa daya aktif, daya reaktif, daya semu, power factor,arus, dan rugi daya jaringan. Untuk tegangan jatuh diambil pada masing masing bus. Nilai aliran daya yang dihasilkan berdasarkan hasil simulasi menunjukan bahwa sistem distribusi DC menghasilkan aliran daya yang lebih besar jika dibandingkan dengan sistem distribusi AC, dan kondisi operasi terbesar pada kondisi loading-unloading nilai aliran daya DC total lebih besar dengan AC. Sebagai hasil dari rekonfigurasi sistem distribusi listrik AC menjadi DC nilai tegangan jatuh tiap bus pada sistem distribusi menjadi lebih kecil dan untuk nilai tegangan jatuh selalu memiliki nilai dibawah standar yang ditentukan oleh IEC 5%. Sebaliknya nilai rugi daya pada sistem distribusi DC berdsarkan hasl simulasi memiliki nilai yang lebih tinggi dibanding sistem distribusi AC. Apabila dalam selanjutnya

In order to reduce the impedance value of the electrical distribution system on the ship, it is necessary to reconfigure the electricity distribution system on the tanker from AC to DC. With the reconfiguration of the system from AC to DC, the impedance value of the system will decrease because there is only resistance (R). As a result of the impedance value dropping, the value of the voltage drop and power loss will also decrease. Decreasing the voltage drop can have a good effect as electrical components will last longer. The research process begins by modeling a single line diagram of the electricity distribution system on a tanker. In this study, power flow simulation was carried out using simulation software. Data retrieval is taken by comparing the default distribution system on tankers, namely AC and then changing or reconfiguring it to DC. Data retrieval is taken on several ship operating conditions, namely sailing, leaving-arriving, loading-unloading, and at port. Based on the simulation results obtained, the results of the power flow of each bus, the simulation results are in the form of active power, reactive power, apparent power, power factor, current, and network power loss. For the voltage drop is taken at each bus. The resulting power flow value based on the simulation results shows that the DC distribution system produces a larger power flow when compared to the AC distribution system, and the largest operating condition is in the loading-unloading condition, the total DC power flow value is greater than AC. As a result of reconfiguring the AC power distribution system into DC the value of the voltage drop for each bus in the distribution system becomes smaller and the value of the voltage drop always has a value below the standard specified by IEC 5%. On the other hand, the value of power loss in the DC distribution system based on the simulation results has a higher value than the AC distribution system.
