Abstract

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 that 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 from 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

The target of stand-alone hybrid power generation system was to supply the load demand with high reliability and economically as possible. To design these criteria the optimal design of the proposed configuration should be done by using intelligent optimization technique.  This study utilized Genetic Algorithm method to determine the optimal capacities of hydrogen, wind turbines and micro hydro unit according to the minimum cost objective functions that relate to these two factors. In this study, the cost objective function included the annual capital cost, annual operation maintenance cost, annual replacement cost and annual customer damage cost. The proposed method had been tested in the hybrid power generation system located in Leuwijawa village in Central Java of Indonesia. Simulation results showed that the optimum configuration can be achieved using 19.85 ton of hydrogen tanks, 21 x 100 kW wind turbines and 610 kW of micro hydro unit respectively. DOI: http://dx.doi.org/10.11591/telkomnika.v10i6.1326

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

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%.

Abstract

This paper presents the design of DC micro grid with a load-based battery discharge method for remote island electrification utilising marine currents and solar photovoltaic. To anticipate the intermittent, a load-based battery discharge method is proposed. A centralized battery storage is sized according to the unfilled load demand by the marine current and the solar PV. Thus, the length of the turbine diameter is varied to meet the optimum system size. Hourly data of marine current speed from Cipalulu Strait in Maluku, Indonesia is provided. Data at a typical time, shows that the marine current peak power occurs every 6 hours perday, whereas the PV is at noon. The loads divide into 6 categories, including household 1, household 2, villagse office, school, mosque, and public health center with the peak demand as 112 kW and 856 kWh perday. All loads, mainly for lightings and electronic equipment work in 24 V DC through converters. The distribution network employs 320 V DC connecting from the power plan to the community residents. Simulations demonstrate that the battery size, solar PV, and turbine radius matches to meet the loads. Simulations also show that the battery utilization meets its current and capacity, meaning that an optimum size and filling the load profile can be smoothly conducted.

Abstract

The development of charging technology in Autonomous Rapit Rail Transit (ART) vehicles uses a wireless power system by optimizing. The selection of the power transfer method uses an Inductive coupling of the LCCL model with a wide variation in the cross-section of the wire and the diameter of the fixed coil. Scenario testing by installing a power transfer system on ART facilities, testing is carried out on coil inductance, resonance coupling gap and power efficiency. Optimum power transfer is obtained on coils with a cross-sectional area of 1.5 mm / 6.13 μH and the highest power transfer efficiency of 40% at a distance of 0.5cm.

Abstract

Hidroponik merupakan salah satu metode penanaman tumbuhan yang dapat diaplikasikan secara luas. Salah satu faktor yang mempengaruhi perkembangan tanaman hidroponik adalah kandungan kadar pH yang terdapat pada aliran air dimana kadar pH tersebut akan berubah seiring penambahan nutrisi saat aliran air yang terus menerus didaur ulang, kadar pH yang tidak stabil dapat menyebabkan pertumbuhan tanaman menjadi lambat dan tidak subur. Selain itu, suatu sistem hidroponik membutuhkan sumber energi listrik yang cukup besar karena penyalaan pompa yang dilakukan secara terus menerus selama 24 jam menyebabkan kebutuhan listrik menjadi besar. Disisi lain, potensi energi terbarukan yaitu energi matahari yang memanfaatkan solar panel pada kelompok Hidroponik Simomulya sangat besar. Maka dari itu dirancanglah sistem dengan inovasi hidroponik yang bertenaga energi matahari yang dilengkapi dengan sistem timer yang dapat mengatur lamanya pengairan dalam sistem hidroponik serta penggunaan sensor pH dan nutrisi dalam proses pertaniannya. Pada sistem ini pompa difungsikan sebagai alat untuk mengalirkanair ke pipa-pipa yang berisikan tanaman hidroponik, aliran tadi akan kembali lagi pada tandon besar yang mana letak dari pompa tersebut. Kemudian untuk mengatur lamanya pengairan dalam sistem hidroponik, kami menggunakan timer sebagai pengatur waktu penyalaan pompa, sehingga pompa tidak mudah panas dan mengurangi pemanfaatan sumber energi listrik. Oleh karena itu, dengan menerapkan inovasi automatic solar water pump pada hidroponik, diharapkan dapat mengatasi permasalahan pada sumber energi listrik dan pemakaian pompa secara terus menerus. Serta mampu meningkatkan produktifitas kelompok hidroponik Simomulya.
