Abstract

Konsep pelabuhan ramah lingkungan atau dikenal dengan istilah green port kini diterapkan oleh seluruh negara-negara di ASEAN yang bertujuan untuk mengurangi tingkat pencemaran laut, polusi udara serta berbagai dampak kerusakan lingkungan yang ditimbulkan oleh berbagai aktifitas bongkar muat di pelabuhan. Salah satu upaya dalam mewujudkan konsep green port yang diaplikasikan pada container crane adalah konsep elektrifikasi, yaitu menggunakan sumber energi listrik yang sebelumnya menggunakan bahan bakar fosil dialihkan dengan energi terbarukan. Kondisi di lapangan yang tidak menentu sesuai dengan faktor lingkungan yang terlibat dapat menyebabkan suatu sistem mengalami kegagalan. Short circuit adalah hubungan yang disengaja antara konduksi melalui hambatan atau impedansi yang memiliki perbedaan yang cukup potensial. Gangguan short circuit terjadi ketika konduktor yang memiliki tegangan yang terhubung ke konduktor tegangan lain atau terhubung langsung ke konduktor yang bersifat netral (ground). Oleh sebab itu diperlukan adanya sistem koordinasi proteksi untuk meminimalisir adanya gangguan pada sistem kelistrikan, salah satunya dengan menggunakan circuit breaker. Pada penelitian ini dilakukan simulasi menggunakan software ETAP untuk mengetahui besar arus dari gangguan short circuit dan perencanaan sistem koordinasi proteksi setiap circuit breaker pada komponen yang membutuhkan daya besar dengan arus hubungan singkat maksimal yaitu 9,882 kA pada motor hoist, 3,586 kA pada motor boom, 1,683 kA pada motor trolley dan 4,415 kA pada motor gantry dengan keseluruhan disuplai dengan energi terbarukan. Pengujian ini dilakukan pada beberapa konfigurasi suplai daya dan variasi skema operasi dari motor utama. Diharapkan juga nantinya akan menghasilkan solusi untuk pengaturan sistem koordinasi proteksi circuit breaker pada container crane.

Abstract

Beberapa pelabuhan di negara ASEAN saat ini mulai menerapkan konsep pelabuhan ramah lingkungan atau sering disebut dengan istilah green port. Pemanfaatan energi terbarukan seperti contohnya energi surya digunakan untuk menyuplai sistem kelistrikan yang ada di pelabuhan, salah satunya sistem kelistrikan container crane. Karena pemanfaatan energi terbarukan sebagai sumber listrik masih minim, sehingga masih belum pasti apakah pemanfaatan energi terbarukan dapat mempengaruhi gangguan stabilitas pada sistem kelistrikan. Selain itu, kondisi di lapangan yang tidak menentu dapat menyebabkan gangguan kestabilan pada sistem kelistrikan. Gangguan ini disebut sebagai gangguan transien. Banyak hal yang dapat mempengaruhi kestabilan transien salah satunya apabila terjadi hubungan arus singkat (short circuit) yang dapat menyebabkan gangguan transien. Menggunakan metode simulasi dengan ETAP, dilakukan analisis kestabilan transien dengan menggunakan 2 sumber listrik yang berbeda yaitu PLN & generator dan photovoltaic (PV). Didapatkan bahwa penggunaan PV sebagai sumber menghasilkan kestabilan pada sistem kelistrikan container crane yang memenuhi standar. Respon tegangan pada setiap skenario menghasilkan hasil yang berbeda-beda. Studi kasus pada simulasi kestabilan transien yaitu dengan memberikan gangguan hubungan singkat di busbar terdekat motor di detik ke-1 hingga detik ke-1.15. Respon tegangan yang dihasilkan pada skenario motor gantry yaitu sebesar 94.5%. Sedangkan respon tegangan yang dihasilkan pada skenario motor boom yaitu sebesar 94.64%. Lalu pada skenario motor trolley respon tegangan yang dihasilkan sebesar 94.48%. Pada skenario motor hoist respon tegangan yang dihasilkan sebesar 94.51%. Adapun respon frekuensi yang dihasilkan oleh simulasi PV sebagai sumber listrik yaitu sebesar 100% pada semua skenario yang dibuat.

Abstract

Pelabuhan petikemas tak lepas dari proses bongkar muat barangnya. Proses tersebut menggunakan alat berat berbahan bakar kurang ramah lingkungan. Saat ini pelabuhan petikemas di dunia tengah menerapkan konsep pelabuhan hijau ramah lingkungan (green port). Pengoperasian segala alat industri maupun produksi diusahakan dapat mengurangi jumlah polusi. Maka muncul konsep bahan bakar yang dapat diperbarui, seperti matahari, angin, dan sumber daya alam lain yang dapat menunjang terciptanya konsep pelabuhan ramah lingkungan. Container crane di pelabuhan menjadi alat berat utama dalam proses bongkar muat. Crane umumnya disuplai listrik dari PLN dan generator diesel, namun pada penelitian ini dicoba dengan suplai sumber daya energi terbarukan, seperti panel surya, dengan memodelkan one-line diagram container crane menuju pemodelan berbasis aplikasi simulasi ETAP. Kondisi panel surya yang berkarakteristik tegangan, frekuensi output yang berbeda dengan energi listrik dari PLN dan generator diesel, perbandingannya dicoba untuk dianalisa. Penelitian kali ini hanya fokus pada aliran daya yang terdapat dalam sistem kelistrikan container crane. Baik itu efisiensi tiap motor, rugi daya, hingga tegangan jatuh yang terjadi. Setelah pemodelan dan simulasi, didapatkan hasil bahwa suplai panel surya (PV) cukup bisa digunakan sebagai sumber daya untuk suplai sistem kelistrikan container crane. Pada suplai PV kali ini menggunakan output tegangan inverter sebesar 0,38 kV. Simulasi suplai PV menghasilkan efisiensi daya yang lebih rendah dari suplai PLN dan generator, serta tegangan jatuh yang lebih tinggi dari suplai PLN dan generator. Namun, pada tiap skenario suplai PV, efisiensi daya dan tegangan jatuhnya masih dalam batas standar IEC dan IEEE. Contohnya saat skenario motor gantry, efisiensi daya sebesar 94,44%, dan tegangan jatuh 0,274%. Lalu pada skenario motor boom, efisiensi daya 94,43% dan tegangan jatuh 0,457%. Pada skenario motor trolley, efisiensi daya 94,44% dan tegangan jatuh 0,374%. Pada skenario motor hoist, efisiensi daya 94,76% dan tegangan jatuh 0,269%.

Abstract

Ship with a dynamic positioning system has the ability to maintain her position dynamically. To be able to maintain the position, generally, ship with a dynamic positioning system have several thrusters located at bow or stern of the ship. Based on the propulsion system, there are 2 types of thruster which are mechanical thruster and electrical thruster. In electrical type, the thruster is driven by an electric motor supplied from the generator. In addition, on dynamic positioning vessel equipped with the electrical thruster, there are also VFD or Variable Frequency Drive to control the speed of motor thruster. The use of VFD components in the system may cause harmonic interference. Harmonic itself can be regarded as distortion in the sinusoidal waves due to the interference of other waves that have integer frequency multiples of their fundamental frequency due to the operation of non-linear thruster motor. Some of the most affected components of this distortion are the communications equipment and the components used for measurement. This research conducted an analysis of harmonic disturbance arising from the operation of 2 units bow thruster on DP Ship by simulating 6 scenarios of generator configuration using simulation software. The results from this research were total harmonic distortion value or  VTHD of the system that complies with standards and rules, also the specification of a passive harmonic filter to reduce the VTHD value at the specific harmonic order.

Abstract

Container port’s loading-unloading process is still using heavy equipment with less eco-friendly fuel. However, currently, several container ports are implementing an eco-friendly port (green port) concept. Renewable natural resources, such as the sun’s heat energy, are used as an alternative to supports the green port concept. Container cranes, the main heavy equipment in the loading and unloading processes, are generally supplied with electricity from PLN and diesel generators. In this research, it was tried by modeling container crane’s one-line diagram into ETAP, but by adding renewable energy resources simulation, such as solar panels. Solar panel’s characteristics, such as voltage and output frequency are different from PLN and diesel generators. Then, the difference results will be analyzed. After the simulation, results in comparison, known that solar panels can be used for container crane’s electrical system supply. In this study, the PV’s inverter output voltage is 0.38 kilo-volt. The PV supply simulation results in lower power efficiency and higher voltage drop than the PLN and diesel generator’s supply. As for each PV supply scenario, power efficiency and drop voltages are still within the IEC and IEEE standard limits. For example, in the gantry scenario, the power efficiency is 94.44%, and the drop voltage is 0.274%.

Abstract

Basically a ship has a variety of conditions, namely cargo handling, anchoring, maneuvering, and sailing its requires large electricity consumption. The quality of the voltage is not good will cause damage to electrical equipment on board. Disturbances that occur in electrical system of MT. X may result in a decrease in the performance of existing electrical equipment on the vessel and affect a certain condition as in loading-unloading conditions the time required for loading and unloading becomes longer due to interference with the electrical system. The MT.X tanker system has 5 (five) main busbars: BUS 1, FEEDER PANEL, DSB 2, DSB 3 & 4, and DSB 6. The MT tanker. X has a generator of 3 units with a power of 680 kw each, a frequency of 60 hz and a voltage of 450 V. Transient disturbance analysis under loading-unloading condition occurs transient response due to starting ballast pump where the voltage rises and then drops within 0.5 seconds with the highest value of 100.44% at 4.01 seconds and the lowest value is 99.50% to 4.81 can then reach steady state conditions at 99.9%, which does not exceed the IEEE standard limits. In harmonic disturbances under loading-unloading conditions, in the feeder panel connecting the harmonic source with load at the 5th order, the value of VIHD is 8.77%, which exceeds the IEEE standard of 5%. While the value of VTHD in loading and unloading conditions also exceeded the predefined standard limits. After installation of the filter, it can be seen that the value of VIHD at the 5th order in loading-unloading condition decreased to 3.6% after the installation of filter on feeder panel, or equal to decrease as much as 5.17%. The decline in the value of VIHD has fulfilled the IEEE 519-2014 standard of 5% on each individual order. Meanwhile, VTHD value in loading-unloading condition also decreased, from 11.18% to 7.02%.

Abstract

Electric propulsion system is ship propulsion system using electric motor to replace performance of main engine. Submersible ships use DC motor as electric propulsion system because DC motor has advantages of speed control and lower propulsion noise when submersible ship is at submerge condition. Design of electric propulsion system is using two DC motor that are connected in series. Battery and generator as its power supply. Designs of electric propulsion system that will be reviewed here are using ohmformer and without using ohmformer. Those designs will be simulated using MATLAB Simulink. The results of the simulation are that the design using ohmformer is greater in speed and power than without using ohmformer. Because of using ohmformer can control input voltage of DC motor that use generator as its power supply. Meanwhile, ohmformer-less design has constant input voltage that use battery as its power supply. Next, design of using ohmformer can be used for silent run (low speed), sailing run (medium speed) and quick run (high speed). Then design of without using ohmformer can be used for sailing run (medium speed).
