Abstract

Pembangkit listrik tenaga mikrohidro adalah salah satu sumber energi listrik terbarukan saat ini dengan memanfaatkan tenaga air berskala kecil untuk penggeraknya. PLTMH pada umumnya memiliki ruang kontrol yang berada jauh dengan sistemnya, sehingga dibutuhkan suatu sistem monitoring. Penggunaan sistem monitoring berbasis nirkabel menjadi salah satu solusi untuk mengatasi masalah tersebut dengan proses pengiriman informasi yang cepat dan mudah. Penelitian ini merancang suatu model routing data dengan perancangan hardware dan software pada komunikasi data. Sistem dibangun menggunakan mikrokontroller arduino dan komunikasi frekuensi Xbee dengan protocol zigbee. Pengujian dilakukan dengan menggunakan berbagai macam topologi yaitu topologi pair, star, mesh, tree, dan x dalam model routing data baik dalam lingkungan indoor maupun lingkungan outdoor. Hasil yang didapat berdasarkan pengujian pada lingkungan indoor menunjukan Xbee tetap dapat mengirim dalam ruangan yang memiliki penghalang dengan jarak 21m, sedangkan pada pengujian outdoor, Xbee dapat tetap mengirim dengan jarak maksimum 120.5m menggunakan model topologi x. Berdasarkan semua pemodelan yang telah dilakukan, topologi x merupakan model yang dianggap paling berhasil walaupun memiliki kelemahan dalam tingkat kerapihan penerimaan data namun dari tingkat keamanannya ketika terjadi masalah dengan salah satu node, topologi x masih memiliki jalur lain untuk dapat mengirimkan data ke penerima. Micro hydropower plant is one of the current renewable electrical energy by making use of small-scale water power for propulsion. MHPP generally has a control room that was away with the system, so we need a monitoring system. The use of wireless-based monitoring systems into one solution to overcome these problems with the delivery process information quickly and easily. Therefore, we designed a model of routing data by designing hardware and software in data communication comprising Arduino microcontroller and Xbee frequency communication with ZigBee protocol. Testing is done by using a variety of topologies, namely topology pair, star, mesh, tree, and x in the model routing of data in both the indoor and outdoor environment. The results obtained by testing the indoor environment is Xbee can still send in a room that had a barrier at a distance of 21m, while the outdoor testing Xbee can still send more than the maximum distance delivery Xbee 70.5m in research that is by using the model topology x. Based on all the modeling that has been done, topology x is the model that is considered the most successful even though it has weaknesses in the level of data reception tidiness. But the level of security has the advantage that when there is a problem with one of the nodes, the x topology still has another path to be able to send data to the receiver.

Abstract

Gas Insulated Switchgear Extra High Voltage (GISTET) is a power system component that has a function as a distribution center (transmission) that connects the extra high voltage transmission system through distribution channels or substations. Based on the installation of GISTET equipment, relying on hexafluoride gas (SF_6) as an insulating medium on the equpment. Equipment at GISTET is not always in good condition, GISTET also often experiences problems. One of the distrubances that GISTET often experiences is the leakage of SF6 gas at the PMT (circuit breaker). This requires a treatment called a GISTET overhaul. So in this paper the author will analyze the SSF_6 gas leak as insulation on the PMT (circuir breaker) at GISTET Saguling. According to the results of the calculations in this final project, the gas pressure of SF_6 and the breakdown voltage of PMT are interrelated. At the pressure when the gas leak occurs is at a value below 5kgf/cm2it is able to with stand the voltage. Penetrating with a high value so it is very effective to reduce arc fire. In addition, the SF_6 gas pressure is also related to the arc speed because the lower the pressure value at the time of gas leakage, the arc speed decreases, so the arc will be slow to muffle.

Abstract

Pesatnya perkembangan teknologi monitoring saat ini membantu manusia mempermudah melakukan pekerjaan. Sebagai contoh, monitoring PLTMH dapat digunakan untuk memperoleh data untuk memprediksikan kebutuhan energi listrik. Data yang akan digunakan dihasilkan dari proses pengambilan, pengiriman, penerimaan sampai data dapat ditampilkan dan disimpan dalam piranti penyimpan. Sistem monitoring PLTMH ini berbasis JSN, membutuhkan modul komunikasi serta data logger. Penempatan logger data diperlukan model yang paling sesuai untuk memenuhi spesifikasi data yang diinginkan dan dapat disimpan dalam piranti penyimpanan dalam format “.txt”. Pada penelitian ini digunakan 2 model. Model 1 menempatkan logger data pada rangkaian pengirim dan Model 2 pada rangkaian penerima, sehingga parameter keberhasilan terlihat pada spesifikasi kesamaan data yang dihimpun berdasarkan waktu dan disimpan dalam piranti penyimpanan serta ditampilkan pada serial monitor. Hasil pengujian sampel akuisisi data yang diambil menunjukkan kecepatan putar sebesar 4693 rpm dan frekuensi 156 Hz. Data ini ditampilkan pada serial monitor dan piranti penyimpanan menunjukkan data yang sama. Uji Model 1 tidak menghasilkan data yang bersesuaian dengan pembacaan sensor, sedangkan uji Model 2 yang menempatkan logger data pada rangkaian pengirim dihasikan data yang bersesuain berdasarkan setting waktu pada RTC untuk waktu nyata, serta kesesuaian dari pembacaan sensor pada SD Card maupun serial monitor. Sehingga perancangan Model 2 lebih sesuai untuk penerapan sistem monitoring akuisi data PLTMH berbasis JSN yang informasi datanya dapat digunakan dalam keperluan peramalan energi pada masa mendatang. The rapid development of monitoring technology is currently helping humans make it easier to do work. For example, monitoring of PLTMH can be used to obtain data to predict electricity demand. The data to be used is generated from taking, sending, and receiving until the data can be displayed and stored in a storage device. This MHP monitoring system is based on JSN, requiring communication modules and data loggers. Placement of the data logger requires the most appropriate model to meet the desired data specifications. It can be stored in a storage device in “.txt” format. This study used two models. Model 1 places a data logger on the sending circuit and Model 2 on the receiving circuit so that the parameters of success are visible in the data similarity specifications collected by time, stored in a storage device, and displayed on a serial monitor. The test results for the data acquisition samples showed a rotational speed of 4693 rpm and a frequency of 156 Hz. This data is displayed on the serial monitor, and the storage device shows the same data. The Model 1 test did not produce data that corresponded to sensor readings, while the Model 2 test, which placed a data logger on the sending circuit, generated data that corresponded to the time setting on the RTC for real-time, as well as the suitability of the sensor readings on the SD Card and serial monitor. So the design of Model 2 is more suitable for implementing a JSN-based MHP data acquisition monitoring system whose data information can be used for future energy forecasting purposes.

Abstract

Indonesia's renewable energy mix offers an alternative to conventional fossil fuels. Indonesia has made a significant commitment to the role of exploiting this new energy in accordance with the Paris Agreement. This paper proposes the design of a microgrid architecture for a solar and wind hybrid power plant with grid-connected configuration and micro-scale power plant modeling in Ciheras Village, Cipatujah District, Tasikmalaya Regency, West Java. This architecture is divided into three scenarios in order to determine the best design qualities. The first scenario involves 50% photovoltaic (PV) and 50% wind turbine (WT), the second 60% PV and 40% WT, and the third 70% PV and 30% WT. The findings of the grid-connected microgrid were compared using supporting software, HOMER Pro. The various scenarios yielded performance analysis and renewable energy contribution. Modeling, calculation, simulation, and analysis demonstrate that the first scenario's potential energy output produces 25,655 kWh/year with an 88.2% Renewable Fraction (RF). The second scenario generates 26,194 kWh of energy per year, with a renewable fraction of 87.8%. The third scenario is the best based on the participation and role of distributed energy (PV-WT), with a higher amount of energy output of 30,691 kWh/year and a higher renewable proportion of 89%.

Abstract

The aim of this research to identify areas requiring further attention to enhance electricity distribution efficiency. Data collection is conducted through observation and documentation methods to obtain secondary data such as Single Line Diagram, Distribution Transformer Load Current, Substation Voltage, Conductor Type, Conductor Length, and Conductor Cross-Sectional Area. Secondary data is processed and analyzed to obtain the conductor resistance value, conductor/line power losses, transformer power losses, total power losses, and total energi losses occurring in the distribution network using mathematical calculations, followed by simulation using the ETAP (Electrical Transient Analysis Program) application. After manually calculating power losses in the PT. PLN (Persero) ULP Banda distribution network at Penyulang Nusantara, which reached 7.84034 kW, the simulation results using the ETAP software show 7.8 kW, with a power loss percentage of 0.69% relative to the load. Following the simulation of improvement efforts using ETAP (conductor uprating and load balancing), power losses decrease to 4.4 kW (a reduction of 3.4 kW), with a percentage of 0.39%. The energi losses before improvement are 5,645.045 kWh (1.802%), and after improvement, it becomes 3,168 kWh (a reduction of 2,477 kWh) with a percentage of 1.59%. The improvement efforts result in savings of IDR 3,578,586.91.
