Abstract

Salah satu cara memanfaatkan sumber energi terbarukan adalah dengan menggunakan sel surya yang mengubah energi cahaya matahari menjadi energi listrik. Sebuah converter umumnya diperlukan untuk menyesuaikan tegangan keluaran sel surya dengan kebutuhan aplikasinya. Salah satu jenis konverter yang dapat digunakan yaitu konverter boost, yang dapat menghasilkan tingkat tegangan pada keluarannya lebih tinggi dari masukannya. Keluaran dari sel surya yang bervariasi tergantung pada perubahan iradiasi cahaya matahari menjadi masukan bagi konverter. Pada penelitian ini metode pengendalian sliding mode control (SMC) dimanfaatkan untuk mengurangi osilasi pada tegangan keluaran konverter boost. Penelitian dilakukan dengan cara simulasi menggunakan MATLAB/Simulink pada kondisi sistem pengendalian loop terbuka dan loop tertutup. Nilai settling time dan selisih tegangan keluaran saat sebelum terjadi gangguan dan setelah terjadi gangguan berupa tegangan masukan yang bervariasi dan beban yang bervariasi dianalisis.

Abstract

ABSTRAKPeningkatan kebutuhan listrik di berbagai sektor serta belum meratanya elektrifikasi di daerah terpencil terutama wilayah timur Indonesia membuat pembangkit energi listrik terbarukan saat ini terus dikembangkan, salah satunya adalah PLTMh. Penggunaan generator induksi tiga fasa berpenguat sendiri pada PLTMh menjadi pilihan yang tepat untuk memenuhi kebutuhan energi di tempat yang terisolir atau belum adanya daya reaktif jaringan listrik. Penggunaan beban listrik akhir-akhir ini banyak menggunakan komponen elektronika daya yang salah satu komponennya merupakan penyearah yang merupakan jenis beban nonlinear. Penelitian bertujuan untuk mengetahui karakteristik generator induksi tiga fasa berpenguat sendiri terhadap pengaruh pembebanan penyearah serta menganalisis distorsi harmonik tegangan dan arus dengan variasi kecepatan, nilai pembebanan, dan nilai kapasitor. Hasil simulasi menunjukan bahwa variasi kecepatan dan pembebanan berpengaruh terhadap keluaran generator induksi. Tegangan keluaran generator induksi saat berbeban penyearah lebih besar dibandingkan saat beban resistif untuk daya beban yang sama. Penggunaan beban penyearah menimbulkan harmonisa yang menyebabkan arus dan tegangan menjadi terdistorsi. Pengujian harmonik menghasilkan nilai THDv keluaran generator induksi berada pada rentang 2,165% - 4,827%, untuk THDi generator berada pada rentang 1,916% - 4,404%, THDi kapasitor pada rentang 3,684% - 16,246%, dan THDi beban pada rentang 28,965% - 30,512%. Dengan demikian nilai THD keluaran generator induksi tiga fasa pada kecepatan berbeda masih berada dibawah batas yang diizinkan.Kata Kunci : Generator induksi tiga fasa, karakteristik generator, penyearah tiga fasa, harmonik ABSTRACTThe increase in electricity demand in various sectors and the uneven electrification in remote areas, especially eastern Indonesia, have made renewable energy plants currently continue to be developed, one of which is PLTMh. The use of self-reinforced three-phase induction generators at PLTMh is the right choice to meet energy needs in isolated places or the absence of reactive power in the power grid.The use of electrical loads lately uses a lot of power electronics components, one of which is a rectifier which is a type of nonlinear load. The study aims to determine the characteristics of self-reinforced three-phase induction generators on the effect of rectifier loading and analyze voltage and current harmonic distortions with variations in speed, loading value, and capacitor value. The simulation results show that variations in speed and loading affect the output of the induction generator. The output voltage of the induction generator when the rectifier is loaded is greater than when the load is resistive for the same load power. The use of rectifier loads gives rise to harmonics that cause currents and voltages to be distorted. Harmonic testing resulted in the THDv value of induction generator output in the range of 2.165% - 4.827%, for THDi the generator was in the range of 1.916% - 4.404%, THDi capacitor in the range of 3.684% - 16.246%, and THDi load in the range of 28.965% - 30.512%. Thus the THD value of the output of the three-phase induction generator at different speeds is still below the permissible limit.Keywords : Three-phase induction generator, generator characteristics, three-phase rectifier, harmonic

Abstract

Generator is one of the important equipment in a generating system seeing their role as the initial driver. In development and with the aim of efficiency, namely without using a lot of additional equipment, the main generator that has been connected to the compressor and turbine can be selected and used as a replacement for the previous components by means of, the generator is converted into a motor using a Static Frequency Converter (SFC) to then function as a starting drive. Static Frequency Converter (SFC) connects the generator input terminal with the supply from the outside network and then adjusts the rotation during the generator starting process. The main generator which is a synchronous generator is converted into a synchronous motor as a starter motor. Static Frequency Converter (SFC) consists of a rectifier circuit and an inverter where in the starting process the circuit acts as an AC-DC and DC-AC converter. The initial value used for simulation using Simulink Matlab R2021b software is in accordance with the technical data of static starter block 3 PT. Indonesia Power Grati POMU. Based on the results of calculations and simulations, it shows that the use of a Static Frequency Converter (SFC) by inducing the generator into a motor reaches 2300 rpm in the 28th second with the efficiency level reaches 52,551% and an average power used is 71,711W. Keywords: Generator, Static Frequency Converter (SFC), starting device

Abstract

In order to meet the electricity demand, we need to build a reliable distribution system. However, studies found that providing a service without interruption is challenging, especially avoiding voltage drop interruption remains a difficult task. Although voltage drop interruption is ineluctable, the distribution system usually can tolerate it at a certain level or threshold. Based on the regulation standard by the Ministry of Energy and Mineral Resources of Indonesia in 2009, the safe thresholds are between -10% to +5% of the standard value. As a part of the maintenance procedure, an engineer must ensure that an electrical power distribution system follows those rules to avoid voltage drop interruptions. This study observed the power flow of four connected feeders (Buluagung, Glagah Sari, Tutur, and Kayoman) at the Sukorejo main substation. The electrical power flow of each feeder fluctuated as follows: for Buluagung, the maximum voltage drop was 4.85%, Glagah Sari was 6.65%, Tutur was 2.59%, and Kayoman was 18.89%. Kayoman had te highest voltage drop, and the value passed the defined standard from the Ministry. Thus, this study proposed a framework to reduce the voltage drop value in Kayoman by adding a capacitor bank by analyzing the loss sensitivity along with the norm method. This study performed eight simulations and simulation number four, with additional capacitor installation on buses 8, 9, 12, and 16, giving the optimal result as the voltage drop value reduced to 8.71% for Kayoman. The real and reactive power losses were 934.43 kW and 1,303.54kVAR, respectively.Keywords: distribution system, loss-sensitivity analysis, reactive power difference, voltage drop

Abstract

This paper describes the simulation design of a boost converter that has a high voltage gain. High voltage gains are obtained using the new z-source dc-dc boost converter topology circuit. This converter uses an impedance network which is used as a bridge between the source and the converter. The Z-source converter overcomes the conceptual, theoretical and limitations of conventional voltage source converters and current source converters. The stress on the diodes and switches is lower than the boost converter, so efficiency is improved. At a low duty cycle, this converter is able to produce a higher voltage gain than the boost converter. Both converters are then tested with the same specifications with the aim of knowing the output comparison between the two converters. The test of the two converters is simulated with the PSIM application and analyzed at several stages of testing. The test includes the specifications of the components used, analysis of each component in transient and steady state conditions, comparison of the voltage gain tested at varying duty cycle values, as well as calculation of voltage stress and current stress on the z-source converter and boost converter circuits.Keywords: boost converter, z-source converter, high voltage gain, voltage stress, current stress, PSIM

Abstract

Gangguan saluran transmisi dalam proses penyaluran listrik memberikan dampak yang sangat besar. Salah satu dampak gangguan pada bulan Agustus tahun 2019 di pulau Jawa yaitu pemadaman listrik sebagian pada sistem kelistrikan Jawa-Bali akibat terjadinya kontingensi saluran transmisi 500 kV Pemalang-Ungaran dan Depok-Tasikmalaya. Pencegah terjadinya pemadaman skala besar diperlukan dengan menyusun skema pertahanan yang dapat mengompensasi dampak dari peristriwa kontingensi tersebut. Skema pertahanan dapat dilakukan dengan melakukan pelepasan beban dan generator tripping. Kedua metode tersebut mampu mengevakuasi daya dengan jumlah yang besar dalam waktu yang relatif cepat, sehingga dapat memperbaiki nilai frekuensi dalam waktu singkat. Respon frekuensi sistem mengalami pemulihan dengan kenaikan frekuensi pada pulau Jawa bagian Barat dan penurunan frekuensi pada pulau Jawa bagian Timur. Hasil dari pelepasan beban berupa pemutusan 6 bus beban dalam 5 tahap utama dari sistem dan hasil dari generator tripping berupa pemutusan 2-unit pembangkit dalam 2 tahap dari sistem.

Abstract

This study describes the effect of Tetrafluoroethane concentration on the dielectric of Carbondioxide gas in a non-homogen AC high field. This research begins with data collection through breakdown voltage testing at the High Voltage Laboratory, Department of Electrical Engineering, Faculty of Engineering, Universitas Brawijaya. Variations of conditions used in the breakdown voltage test include changes in the concentration of Tetrafluoroethane into Carbondioxide gas of 0%, 10%, 20%, and 30% which are calculated based on the total pressure of the mixed gas, the variation of the total pressure of the mixed gas is 2000 mBar, 2200 mBar, 2400 mBar, and 2600 mBar, as well as changes in the gap between 1.5 cm and 3 cm. The test is carried out using high voltage AC. The arrangement of the electrodes used is a needle - plate. The results obtained in this study are the influence of the concentration of R134 into CO₂ gas where the value of the dielectric strength of pure CO₂ gas is lower than that of contaminated CO₂ gas, in this case R134 is the impurity. In addition, variations in the concentration ratio of R134 from 0% to 30% and variations in the ratio of total mixed gas pressure from 2000 mBar to 2600 mBar affect the dielectric strength of the mixed gas. Where the greater the concentration value of R134, the greater the breakdown voltage value and the greater the total pressure value of the mixed gas, the greater the breakdown voltage value.

Abstract

Photovoltaic (PV) systems as a source of renewable electricity generation have experienced rapid development. However, PV systems have several problems, one of which is that the generated electrical power is unbalanced affected by temperature, humidity, irradiation, etc., which makes it difficult to obtain maximum power from PV. In addition, the difference in irradiation levels on each PV module caused by partial shading conditions can cause more than one peak on the PV characteristic curve. This study will compare the performance of the Firefly and Incremental Conductance algorithms in tracking the global peak in the PV characteristic curve. In simulating partial shading conditions, this research uses 6 PV modules connected in series-parallel with 4 test scenarios where each module has a different irradiation value. Simulation testing in this research uses MATLAB-SIMULINK software. Maximum Power Point Tracking (MPPT) simulation results show that from experiments using 4 different test scenarios, the Firefly algorithm obtained an average efficiency of 98.6437%. While the Incremental Conductance algorithm obtained an average efficiency of 78.3448%. So that the percentage of the superiority of the Firefly algorithm over the Incremental Conductance algorithm is 19.9607%.

Abstract

From 2019 until 2020, Microhydro Power Plant (MHP) Units A1 and A2 measured a significant power decrease of more than 75% from their template capacities. Therefore, CSR PT PJ Paiton with PKSDAL Brawijaya University created a program called “Increasing The Power Capacity Of Andungbiru MHP Units A1 And A2 For The Lead Of Safe And Sustainable Electricity In 2022”. In this experiment, Unit A1 will be used as the test object, as the purpose it is to measure the success of the increasing electrical power and quality programs of Andungbiru’s MHP, especially Unit A1. The success analysis needed is in terms of increasing generator power, stability of generator output characteristics, and knowing the level of quality or efficiency of the generator after repairs and also knowing the level of stability of the generator when a fault occurs. The test is carried out in various loadings to get results that can represent the use of Andungbiru’s MHP consumers with a Dummy Load test device and a data logger with the Mod Bus Tool application with RS482 Cable Driver with load intervals of 25%-50%-75%-100%. The characteristics of the generator are considered quite good from the relationship between the variables.Keywords – MHP, Synchronous Generator, Load Variation, Electrical Impact, Desa Andungbiru, Kecamatan Tiris, Kabupaten Probolinggo
