Abstract

Kapal tanker menjadi salah satu jenis kapal yang paling sering digunakan untuk perdagangan. Perdagangan menggunakan tanker pada tahun 2019 sendiri mencapai sekitar 28,6% dari total perdagangan yang menggunakan transportasi laut di dunia. Umumnya, kelistrikan kapal tanker masih disuplai oleh diesel generator yang menggunakan solar sebagai bahan bakarnya yang dapat menyebabkan emisi. Menurut data studi yang dikeluarkan oleh IMO, emisi dari kapal ikut menyumbang 2,2% gas rumah kaca CO2, serta 13% polutan SOx dan 15% polutan NOx dari total polusi udara di dunia. Sehingga, diperlukan inovasi dengan memanfaatkan energi terbarukan seperti penambahan photovoltaic (PV). Sistem distribusi listrik di kapal pada saat ini masih menggunakan arus AC. Namun, beberapa studi memperlihatkan jika sistem distribusi listrik menggunakan arus DC memiliki beberapa keunggulan terhadap sistem distribusi listrik AC. Sistem distribusi listrik DC lebih efisien dikarenakan tidak adanya pengaruh frekuensi dan reaktansi. Hal ini, akan menyebabkan power loss pada sistem distribusi akan semakin kecil sehingga meningkatkan efisiensi pada generator. Penelitian ini dilakukan dengan berbasis simulasi aliran daya. Berdasarkan simulasi yang telah dilakukan didapatkan hasil jika nilai daya aktif dan reaktif setelah dilakukan rekonfigurasi sistem distribusi tidak terdapat perbedaan daya yang signifikan. Selain itu, nilai power loss pada sistem distribusi DC selalu lebih kecil jika dibandingkan dengan nilai power loss pada sistem distribusi AC. Pemasangan photovoltaic (PV) sendiri juga terbukti dapat mengurangi nilai power loss. Nilai power loss tertinggi terdapat pada sistem distribusi AC dalam kondisi loading unloading tanpa menggunakan photovoltaic dengan nilai power loss sebanyak 3,267 kW dan 2,223 kvar atau sekitar 0,23% dari total daya.

Tankers are one of the most frequently used types of ships for trade. Trade using tankers in 2019 reached about 28.6% of the total trade using sea transportation in the world. Generally, electricity for tankers is still supplied by diesel generators that use diesel as fuel which can cause emissions. According to study data released by IMO, emissions from ships contribute 2.2% of the greenhouse gas CO2, as well as 13% of SOx pollutants and 15% of NOx pollutants from the total air pollution in the world. Thus, innovation is needed by utilizing renewable energy such as the addition of photovoltaic (PV). The electricity distribution system on the ship at this time still uses AC current. However, several studies have shown that an electric distribution system using DC current has several advantages over an AC power distribution system. DC power distribution system is more efficient because there is no influence of frequency and reactance. This will cause the power loss in the distribution system to be smaller, thereby increasing the efficiency of the generator. This research was conducted based on power flow simulation. Based on the simulations that have been carried out, the results obtained if the value of the active and reactive power after reconfiguring the distribution system there is no significant difference in power. In addition, the power loss value in a DC distribution system is always smaller than the power loss value in an AC distribution system. The installation of photovoltaic (PV) itself is also proven to reduce the value of power loss. The highest power loss value is found in the AC distribution system in loading-unloading conditions without using photovoltaic with a power loss value of 3,267 kW and 2,223 kvar or about 0.23% of the total power.
