Abstract

Kebutuhan akan listrik di kapal saat ini sangat tinggi, karena hampir semua aktivitas di kapal seperti berlayar, bermanuver, bongkar muat dan lego jangkar membutuhkan konsumsi listrik yang besar. Pada berbagai macam kondisi tersebut perlu diketahui seberapa besar nilai losses tegangan atau tegangan jatuh dan cara untuk melakukan perbaikan tegangan jatuh. Pada penulisan tugas akhir dilakukan kajian secara teknis cara melakukan perhitungan tegangan jatuh secara manual dan membandingkannya dengan simulasi software ETAP. Pada simulasi software ETAP digunakan load flow analysis dan motor acceleration analysis sebagai metode untuk melakukan perhitungan tegangan jatuh secara simulasi. Hasil yang diperoleh terdapat tegangan jatuh terbesar pada kondisi maneuver, saat starting bow thruster terdapat tegangan jatuh selama 60 detik yang tidak sesuai dengan standar IEC 5% dan tidak direkomendasikan oleh IEEE. Setelah dilakukan perbaikan pada bow thruster dengan cara menaikkan tap transformator sebesar 2,5% dengan tegangan sekunder 400V pada hasil running load flow analysis dan memberi kapasitor sebesar 2000 kVAr, tegangan jatuh pada hasil running motor acceleration analysis bahwa tegangan jatuh dapat diturunkan menjadi 13 detik vi pada detik ke 6 – 13 yang sesuai dengan standar IEC dan rekomendasi IEEE. ========================================================================================================== Demand for electricity in the ship currently very high, because almost all activities on board such as sailing, manuevering, loading unloading and anchoring requires large power consumption. Various kinds of such conditions needed a way to determine how much the value of voltage losses or voltage drop and how to make improvements voltage drop. In the final project studied it is technically how to do the calculations manually voltage drops and compare them with ETAP software simulation. In the ETAP software simulation used load flow analysis and motor acceleration analysis as a method for calculating the voltage drop by simulation. The results obtained contained the biggest voltage drop on the conditions of maneuvers, when bow thruster starting contained a voltage drop for 60 seconds which is not in accordance with 5% IEC standard and not recommended by IEEE. After repairs to the bow thruster by increasing the transformer tap at 2.5% with a secondary voltage of 400V on the results of running load flow analysis and provide a capacitor of 2000 kVAr, vltage drop on the results of running the motor acceleration voltage drop analysis could revealed to be 13 viii seconds at the second 6 until 13 are in accordance with standard IEC and IEEE recommendations.
