Abstract

Rekonfigurasi sistem distribusi kelistrikan AC menjadi DC pada kapal tanker dilakukan untuk mengurangi losses daya dari sumber menuju beban listrik. Hal itu disebabkan karena sistem distribusi AC memiliki nilai impedansi, sedangkan pada sistem distribusi DC tidak memiliki impedansi. Dengan berkurangnya losses daya tersebut, akan meningkatkan tingkat efisiensi pada sistem distribusi listrik kapal tanker. Peralatan berupa converter dibutuhkan untuk rekonfigurasi sistem distribusi AC menjadi DC maupun sebaliknya. Dalam penggunaan converter yang merupakan beban nonlinier, memiliki beberapa dampak buruk, salah satunya memberikan distorsi harmonisa pada sistem kelistrikan. Distorsi harmonisa telah diatur oleh klas BKI dengan batas 8% THD. Simulasi dan analisis harmonisa menggunakan software dilakukan untuk mengetahui pengaruh harmonisa pada sistem. Berdasarkan simulasi harmonisa didapatkan nilai THD pada hampir seluruh busbar yang belum memenuhi batas aturan klas BKI. Perencanaan filter pasif single tuned dengan variasi pemodelan posisi pemasangan dilakukan oleh peneliti sebagai solusi dalam menurunkan nilai THD. Beberapa data yang dibutuhkan berupa arus harmonisa, nilai PF, dan besar daya yang mengalir (MVA). Perencanaan filter pasif tersebut berpengaruh signifkan dalam menurunkan nilai THD pada sistem distribusi kelistrikan. Didapatkan penurunan nilai VTHD hingga 1,54 % untuk filter pasif Model A dan 2,09% untuk Model B, dari nilai 12% VTHD pada empat kondisi operasional kapal sebelum sistem dipasang filter pasif. Analisis ekonomi dilakukan untuk mengetahui hubungan perubahan harmonisa dengan kenaikan biaya, sehingga dibutuhkan biaya sejumlah Rp 1.605.546.719,76 untuk filter Model A dan Model B sejumlah Rp 1.894.203.389,86. Dengan efisiensi biaya dan efektivitas penurunan harmonisa, filter pasif Model A merupakan solusi yang lebih efisien dan ekonomis.

Reconfiguration of the AC to DC electrical distribution system on tankers is carried out to reduce power losses from the source to the electrical load. This is because the AC distribution system has an impedance value, while the DC distribution system has no impedance. By reducing these power losses, it will increase the efficiency level of the tanker's electricity distribution system. Equipment in the form of a converter is needed to reconfigure the AC distribution system to DC or vice versa. In using a converter which is a nonlinear load, it has several adverse effects, one of which provides harmonic distortion in the electrical system. Harmonic distortion has been regulated by the BKI class with a limit of 8% THD. Simulation and analysis of harmonics using software is carried out to determine the effect of harmonics on the system. Based on the simulation of harmonics, the THD value is obtained at almost all busbars that do not meet the BKI class rules. Single tuned passive filter planning with variations in installation position modeling is carried out by researchers as a solution in reducing THD values. Some of the data needed are harmonic currents, PF values, and the amount of power flowing (MVA). The passive filter planning has a significant effect in reducing the THD value in the electricity distribution system. A decrease in VTHD value of up to 1.54% for passive filter Model A and 2.09% for Model B was obtained, from a value of 12% VTHD in four ship operational conditions before the system was installed with passive filters. An economic analysis was conducted to determine the relationship between harmonic changes and cost increases, resulting in a cost of Rp 1,605,546,719.76 for Model A and Model B filters of Rp 1,894,203,389.86. With the cost efficiency and effectiveness of harmonics reduction, Model A passive filter is a more efficient and economical solution.
