Abstract

Kapal trimaran merupakan kapal yang memiliki tiga lambung yang saling terhubung. Kapal trimaran juga memiliki bermacam-macam kondisi operasional yaitu bongkar muat (cargo handling), lego jangkar (anchoring), bermaneuver (maneuvering), dan berlayar (sailing) dengan kebutuhan listrik yang beragam. Pada penelitian kali ini akan menganalisa kondisi manuevering dikarenakan kondisi tersebut membutuhkan daya yang besar. Berbagai macam kondisi operasional kapal dapat menyebabkan gangguan sistem kelistrikan. Oleh karena itu kualitas tegangan listrik dan pencegahan terjadinya short circuit menjadi salah satu faktor penting pada sebuah sistem kelistrikan kapal. Buruknya kualitas tegangan yang dihasilkan dapat mengakibatkan penurunan keandalan sistem tenaga listrik dan dapat mengurangi lifetime dari peralatan listirk tersebut. Tegangan jatuh yang terjadi pada beban listrik di kapal sering dihiraukan oleh ABK dan jarang mendapat perhatian khusus. Untuk mengatasi short circuit diperlukan analisa arus short circuit pada sistem kelistrikan kapal trimaran ini. Pada penelitian ini akan dilakukan beberapa perbedaan pembebanan generator untuk mengetahui drop voltage dan short circuit yang terjadi di kapal trimaran. Hasil perhitungan dengan load flow analysis didapatkan tegangan jatuh pada setiap variasi beban mengalami drop voltage (tegangan jatuh) melewati standar IEC (+/-5%) dengan rata-rata diatas 6%. Upaya perbaikan dilakukan dengan metode penambahan kapasitor diterapkan pada beban, masing-masing sebesar 50μF. Dari hasil analisa short circuit didapatkan bahwa pada masing-masing beban mengalami short circuit dengan nilai rata-rata 919 ampere.

Trimaran ship is a ship that has three interconnected hulls. The Trimaran ship also has various operational conditions, named loading and unloading (cargo handling), anchoring, maneuvering, and sailing with diverse electricity needs. In this research, we will analysis the condition of manuevering because these conditions require a large amount of power. Various types of ship operating conditions can cause electrical system disruptions. Therefore the quality of the electricity voltage and the prevention of the short circuits become one of the important factors in a ship's electrical system. The poor quality of the voltage produced can result in a decrease in the reliability of the power system and can reduce the lifetime of the electrical equipment. Drop voltage that occurs in electrical loads on ships is often ignored by ABK and rarely gets special attention. To overcome the short circuit, a short circuit current analysis is needed on the Trimaran ship's electrical system. In this study there will be several differences in generator loading to determine the drop voltage and short circuit that occur on trimaran ship. The results of calculation with load flow analysis show that the drop voltage for each load variation has a drop voltage passing the IEC standard (+/- 5%) with an average of above 6%. Effort for fixxed it by installing capacitors to the load, with 50μF for each. From the results of the short circuit analysis, it was found that each load short circuit occured with an average value of 919 ampere.
