Abstract

Keandalan sistem tenaga listrik dan kualitas daya merupakan salah satu faktor yang sangat penting dalam sistem tenaga. Kualitas daya listrik diartikan sebagai kualitas aliran daya pada suatu sistem. Untuk menentukan kualitas daya listrik terdapat beberapa parameter yang harus diperhatikan, diantaranya adalah nilai jatuh tegangan, nilai rugi - rugi daya,nilai harmonisa, kestabilan frekuensi dan kontinuitas penyaluran daya listrik. Salah satu metode yang dapat digunakan untuk memperbaiki kualitas daya adalah dengan penggunaan distributed generation atau DG pada sistem tenaga listrik. Penggunaandistributed generation dapat mengurangi nilai jatuh tegangan pada saluran tenaga listrik sehingga nilai rugi – rugi daya juga akan menurun. Secara khusus, pada penelitian akan dibahas bagaimana mendesain kapasitas distributed generation yang sesuai kebutuhan sistem serta membahas mengenai pengaruh penempatan distributed generation terhadap rugi – rugi daya serta tegangan pada sistem distribusi radial. Langkah pertama yang harus dilakukan adalah analisis aliran daya (load flow). Setelah hal tersebut selesai maka akan  direncanakan penempatan distributed generation pada beberapa bus untuk membandingkan tingkat kualitas daya yang terbaik serta nilai amplitudo teganganpada sistem setelah terhubung dengan DG.

Abstract

Energy of Photovoltaic is one of energy resource that potential to be developed in Indonesia. Output power of Photovoltaic is changing according to changes of sunirradiance. Energy sources that produce DC low voltage require a step-up converter to increase the voltage before it is converted into AC voltage.To optimize the system, step-up converters must have a high voltage ratio and high efficiency at all of loading level and wide voltage input range. In this research will be compared betweem multistage converter and high voltage ratio boost converter that utilizes combination of pulsewidth modulation (PWM) operating mode and a resonant mode.This converter only requires one switch, so it’s easier in the controlling. This researh results showed with same duty cycle and voltage input, transformer hybrid method can produce power output greater than multistage. The voltage output of hybrid transformer can also achieve steady state faster than using a hybrid converter.So the hybrid converter transformer has the better ability than multistage converter and can be implemented in alternative energy resources that produce a low DC voltage such as photovoltaics.

Abstract

Perkembangan industri peternakan semakin meningkat baik usaha peternakan skala kecil maupun skala besar. Kebutuhan protein hewani dapat dipenuhi dari hasil produksi peternakan baik dari daging maupun susu. Produksi susu dalam negeri hanya mampu mencapai angka 21% dari konsumsi nasional, sedangkan 79% sisanya merupakan pasokan produk dari luar negeri atau import. Susu kambing menjadi salah satu produk peternakan yang umum dikonsumsi oleh masyarakat, karena susu kambing memiliki tingkat manfaat yang banyak khususnya untuk kesehatan manusia. Dalam proses produksi susu kambing, setelah diperas, susu kambing harus dimasak serta diaduk dengan suhu yang tinggi. Proses masak tersebut bertujuan untuk menghilangkan bakteri yang ada di dalam larutan susu. Secara umum, proses ini masih menggunakan kompor gas yang membuat proses ini cukup lama dan cukup memberatkan dari segi biaya operasional. Di sisi lain, potensi energi terbarukan berupa energi matahari sangat besar di kawasan peternakan. Oleh karena itu dirancanglah inovasi alat pasteurisasi bertenaga matahari. Pada sistem ini, alat pasteurisasi beroperasi dengan energi listrik, ketika susu dimasukkan ke alat pasteurisasi, susu akan diberikan kejut listrik sehingga bakteri pada susu kambing secara instan akan mati dan susu siap dikonsumsi, hal ini memiliki keuntungan dari segi waktu jika dibandingkan dengan proses masak. Untuk suplai elektris, sumber energi dari matahari akan dikonversi menjadi energi listrik dan disalurkan menuju alat pasteurisasi untuk menghidupkan alat. Dengan adanya inovasi ini, diharapkan dapat mengenalkan kepada masyarakat mengenai penerapan energi baru terbarukan di bidang peternakan dan dapat meningkatkan produktivitas peternak susu kambing di daerah Plosoklaten, Kediri.

Abstract

Three phase fault is one of a transient phenomenon that must be isolate immediately to prevent losing synchron of generator in power plant, so that the system remain stable. Critical clearing time is maximum time allowed to isolate the system fault so that the system remain stable. Super capacitor energy storage installation to the system is one way to improve CCT value. Super capacitor is one of energy storage that be able to supply and store large amounts of electricity power quickly. Super Capacitor can improve CCT value by muffle oscillation of 3 phase fault. With higher CCT value, then time operation of protection system can be longer. The result is the system remain stable after fault removed and it can be improve transient stability in power system. Within an optimal sizing of super capacitor capacities for the system, then the value of CCT that obtained is higher than protection time operation. So that in this final project will be carried out an optimal sizing of super capacitor for improving transient stability with critical trajectory based on losing synchronism method

Abstract

Permanent Magnet Synchronous Machines (PMSM) have low torque in a number of specific PT. Pertamina RU V Balikpapan will be integrated with electricity sources with PT. PLN. Then there will be a change in the generator operating pattern on the system so it needs to be analyzed again. The protection system aims to isolate the interference quickly, selectively, and coordinatively so that damage to the system can be minimized and the continuity of electric power can be maintained properly. The important thing that must be considered for protection coordination, especially in overcurrent relays, is filling the TDS (Time Dial Setting) parameter. TDS regulates the relay operation time in securing a disturbance. Generally, the TDS value is determined using a manual calculation to obtain a minimum TDS value. However, to get the right TDS value in coordinating with other relays it still uses trial and error methods. In this final project, we will discuss how to calculate the time dial overcurrent relay inverse setting with the adaptive modified firefly algorithm method in the electrical system at PT. Pertamina RU V Balikpapan considers integration with PLN to obtain a minimum TDS value. The result of this final project is to obtain a minimum TDS value in some cases typical types such as the longest channel, consideration of LVCB operating time, and short channels so that it can be well-coordinated with the long lines installed on the same bus.

Abstract

Research and development on the implementation of renewable energy is growing rapidly, especially about photovoltaic (PV) and energy storage. Water pumped energy storage (WPES) is an alternative storage media in a standalone solar power system because of its longer technical life than chemical storage types, such as batteries. To assess the feasibility of WPES implementation as an energy storage in the standalone solar power plant system, the process of sizing the system components needs to be carried out by considering technical and economic aspects. This research will discuss the sizing process of standalone solar power system using WPES with closed loop reservoir systems and its economic analysis. The sizing process is carried out by the method of power balance, energy balance, and volume balance while economic viability is seen from the capital cost, O&M cost, and revenue from electrical energy absorbed by the load. In this study, the daily load profile with energy demand of 79 kWh and peak load of 4.36 kW. The analysis shows the need of 56 kWp PV system, 3800 m³reservoir capacity with 20m head. The calculation shows the technical efficiency of the system is 28.2%. From the economic analysis, the sistem’s payback period is 24 years, assuming the reservoir technical age is 50 years with net present value of Rp 2,072,823,731.86 and return of investment 105%.
