Abstract

Elektrifikasi kapal menjadi salah satu solusi strategis dalam mendukung pengurangan emisi karbon di sektor pelayaran. Penelitian ini membahas analisis teknis pada sistem charging station untuk kapal pandu full-electric di Pelabuhan Tanjung Perak melalui software simulasi Dua konfigurasi sistem diuji untuk mengetahui performa kelistrikan terhadap aliran daya, gangguan hubung singkat, dan harmonisa. Pada sistem charging station 1, ditemukan permasalahan berupa kondisi overload pada trafo dan rectifier di sisi AC dimana load lebih dari 100% serta kabel konektor di sisi DC, meskipun tidak terjadi drop voltage yang signifikan. Arus hubung singkat maksimum mencapai 57,87 kA pada sisi AC dan 15,584 kA pada sisi DC. Nilai THD harmonisa pada Bus 4 mencapai 22,68%, melebihi ambang batas standar 8%. Pada sistem charging station 2, peralatan di sisi AC telah sesuai standar, namun gangguan harmonisa pada Bus 6 dan Bus 7 menunjukkan nilai THD sebesar 48,2% dan 33,12%. Solusi perbaikan dilakukan dengan menaikkan spesifikasi transformator dan rectifier, mengganti kabel konektor dengan penampang lebih besar, serta menyesuaikan perangkat pengaman sesuai hasil analisis arus gangguan. Pemasangan filter harmonisa dapat menurunkan nilai THD ke bawah ambang batas dimana Bus 4 menjadi 7,16%, Bus 6 menjadi 7,74%, dan Bus 7 menjadi 7,08%. Hasil penelitian ini menjadi acuan penting dalam merancang charging station yang andal dan sesuai standar kelistrikan, serta mendukung transisi energi hijau di sektor pelabuhan Indonesia.

Electrification of vessels is a strategic solution to support carbon emission reduction in the maritime sector. This study presents a technical analysis of a charging station system for a full-electric pilot boat at Tanjung Perak Port using simulation software. Two system configurations were tested to evaluate electrical performance in terms of load flow, short circuit faults, and harmonics. In Charging Station System 1, issues were identified such as overload conditions on the transformer and rectifier on the AC side, where the load exceeded 100%, and on the DC side connector cables, although no significant voltage drop occurred. The maximum short circuit current reached 57.87 kA on the AC side and 15.584 kA on the DC side. Harmonic distortion (THD) at Bus 4 was recorded at 22.68%, exceeding the 8% standard limit. In Charging Station System 2, AC-side equipment met standards, but harmonic disturbances at Bus 6 and Bus 7 showed THD values of 48.2% and 33.12%, respectively. Corrective actions included upgrading transformer and rectifier specifications, replacing connector cables with larger cross-sectional sizes, and adjusting protective devices according to short circuit analysis results. The installation of harmonic filters successfully reduced THD values below the standard threshold, with Bus 4 reaching 7.16%, Bus 6 at 7.74%, and Bus 7 at 7.08%. The results of this study provide a valuable reference for designing reliable charging stations that comply with electrical standards and support the green energy transition in Indonesian ports.
