Abstract

Solar panels are one of the renewable and environmentally friendly sources of electrical energy. Renewable energy at this time is often discussed, because non-renewable energy at this time has caused many negative effects on the earth. In utilizing solar panel electrical energy sources is fairly difficult, because to be at its best performance, solar panels must be at a certain irradiation and temperature. But in fact irradiation and temperature always change so that the power produced changes so that the power output is not optimal. Therefore, a tool is needed that is able to find the maximum power point automatically at any irradiation and temperature conditions, therefore in this study Maximum Power Point Tracking (MPPT) is proposed using the Fuzzy-PI method so that the power output produced can always be maximized. The proposed Maximum Power Point Tracking (MPPT) was tested through extreme irradiation and temperature changes and also compared to the Pmax value resulting in a Maximum Power Peak (MPP) accuracy of 94.69 %.

Abstract

At present, humanity's electricity needs are increasing and electricity is flowing directly from PLN which often experiences interruptions which causes power outages, the blackouts themselves are carried out because the load capacity exceeds the specified capacity. Therefore, it is necessary to seek alternative electrical energy as a substitute for extinguishing disturbances. Uninterruptible Power Supply (UPS) is used as an electronic device that can work in conditions where the PLN source is out. This study plans a UPS system that has a voltage sensor to detect blackouts. There is an SSR as a switch from the PLN power supply source to the UPS system. Single Phase Fullbridge Inverter in the UPS system is modulated by the Sinusoidal Pulse Width Modulation (SPWM) method with Fuzzy logic control. A single phase inverter using the SPWM switching technique can produce an output wave close to sine. Based on the results of the tests carried out, the UPS can work with a maximum power of 394.2W and the voltage is kept constant at 219V.

Abstract

Kebutuhan akan sumber energi listrik di era modern sangat tinggi, contohnya baterai. Baterai sendiri kini telah di alih fungsikan  sebagai sumber listrik utama untuk berbagai peralatan elektronik.Baterai yang sering digunakan adalah baterai dengan model Lead Acid yang memiliki keunggulan memiliki spesifikasi tegangan dan arus yang besar serta biaya perawatan yang lebih rendah. Baterai Lead Acid memiliki masa pakai lama, performa tinggi. Baterai mengalami siklus Charge dan Discharge yang menyebabkan penurunan kapasitas dan performa. Oleh karena itu, Untuk mengatasi masalah tersebut diperlukan Estimasi State of Charge (SOC) dengan benar karena keakuratan Estimated State of Charge (SOC) akan mempengaruhi umur dan kinerja baterai. Pada sistem Estimasi State of Charge ini digunakan metode Neural Network digunakan untuk menentukan parameter dan mengontrol kondisi State of Charge (SOC). Sistem ini juga dilengkapi dengan  proteksi jika terjadi Arus dan Tegangan Lebih. Dari hasil penelitian yang dilakukan, estimasi menggunakan metode Neural Network memiliki nilai error yang sangat kecil dibandingkan dengan simulasi estimasi SOC menggunakan aplikasi MATLAB, yaitu 0,17%. Estimasi State of Charge (SOC) menggunakan Neural Network dapat dikatakan memiliki performa yang baik karena nilai error jika dibandingkan dengan simulasi sangat kecil. Dan kelebihan dari Metode Neural Network ini adalah tidak perlunya pemodelan matematika untuk menghitung nilai SOC.

Abstract

Pada penelitian ini dilakukan pengaturan kecepatan motor induksi tiga fasa dengan vector control menggunakan metode Direct Torque Control. Pada metode vector control, pengaturan kecepatan dapat dilakukan dengan mudah karena sistem dibuat seolah-olah menyerupai karakteristik motor DC, di mana pengaturan fluks dan torsi dapat dilakukan secara terpisah. Sistem pada metode Direct Torque Control, didasarkan pada pengaturan fluks dan torsi menggunakan Estimator DTC untuk menghasilkan nilai fluks dan torsi estimasi. Selanjutnya, keluaran dari estimator beserta sektor sudut fluks stator akan menentukan vektor tegangan yang sesuai dengan metode switching Sinusoidal Pulse Width Modulation Inverter, sehingga keluaran dari inverter dapat mengatur kecepatan putaran motor. Untuk memperbaiki hasil respon kecepatan putaran motor digunakan kontroler PID. Penelitian ini dilakukan melalui simulasi menggunakan MATLAB. Motor induksi yang digunakan, memiliki daya 4 KW dengan tegangan 400 Vrms dan kecepatan putaran nominal 1430 RPM. Pengujian dilakukan pada kondisi tanpa beban dan juga berbeban untuk mengetahui performansi sistem. Hasil simulasi menunjukkan nilai rise time 0,08 detik, nilai settling time 0,37 detik, dan nilai overshoot mencapai 14,11 %.

Abstract

Penggunaan photovoltaic sebagai sumber energi terbarukan berkembang dengan pesat. Biaya implementasi photovoltaic sangat tinggi oleh karena itu diperlukan kontrol untuk mengoptimalkan efisiensi dari PV. Karakteristik V-I sel surya adalah nonlinier, berubah terhadap intensitas cahaya matahari dan temperatur permukaan photovoltaic sehingga menyebabkan daya keluaran dari photovoltaic bervariasi. Penelitian ini akan menggunakan zeta converter sebagai DC chooper yang dikontrol oleh MPPT berbasis fuzzy logic controller. Software Power Simulation (PSIM) digunakan untuk mensimulasikan MPPT. MPPT fuzzy logic controller akan dibandingkan dengan MPPT human psychology optimization (HPO). Hasil simulasi menunjukkan MPPT fuzzy mendapatkan akurasi yang sama dengan MPPT HPO dan lebih baik dari rata – rata akurasi tanpa MPPT yaitu 99,98%. Kemudain kecepatan dalam mencari titik maksimum MPPT fuzzy mendapatkan time tracking yang lebih baik jika dibandingkan dengan MPPT HPO yaitu 0,0283 detik. MPPT fuzzy mampu menelusuri daya maksimum pada intensitas cahaya matahari dan temperatur yang berubah-ubah

Abstract

Fuse Cut Out (FCO) is a separation device in medium voltage networks, FCO removal is done by separating the top contact with the fuse carrier. How to remove the fuse carrier in general still uses a manual method with special equipment, namely a 20KV telescopic stick. The use of telescopic sticks is very time consuming and prone to leakage of insulation which affects work safety. In this study, the release of the fuse carrier was carried out with a remote control as a command to release and enter the fuse carrier.  Testing of this tool is carried out at a voltage of 223 Volts AC. The remote control design is able to provide a command signal with a maximum distance of 21 m in real time conditions. The mechanical construction is adapted to the standard clearance distance in the medium voltage network and the results of mechanical manufacturing of the upper contact with the fuse carrier release distance of 207 mm and the upper contact with the pneumatic actuator of 200 m, the compressed air source uses 5bar. The average success was 88.8% Phase R, 77.7% Phase S, 77.7% Phase T. The construction of the fuse carrier drive tool in this study is used in the release of FCO so that release and entry require faster time and optimise work safety.

Abstract

Batteries are essential to many contemporary applications, including electric cars and portable electronics. Overheating and charging time efficiency are the two biggest issues with battery charging. Overheating presents safety hazards and hastens battery deterioration. Due to their inability to regulate temperature, conventional charging techniques like Constant Current - Constant Voltage (CC-CV) result in excessive temperature rises during battery charging, which shortens battery life. A novel approach that helps lessen excessive temperature rises is the Constant Temperature - Constant Voltage (CT-CV) method, according to researchers. In order to avoid excessive temperature increases during the initial charging, the CT technique initially regulates the applied temperature. Second, to guarantee full capacity without causing damage to the battery, the CV technique is used to maintain a steady voltage. A fuzzy logic controller (FLC) control system is used to regulate the temperature and current at the DC-DC converter's output. The FLC control system's goal is to control the duty cycle such that the buck converter's output is 65V 11.5A. The simulation results show that the CT-CV method can reduce the increase in temperature in the battery with an average temperature during the battery charging process of 23.57° C with fuzzy control and 23.71° C with PI control. In addition, by comparing two control systems with the CT-CV method, namely PI and fuzzy, it was found that the fuzzy method was able to accelerate battery charging by 4.16% compared to the PI control.

Abstract

Motor induksi banyak digunakan di industri, namun dalam penggunaannya motor induksi memiliki hal-hal yang kurang menguntungkan seperti nilai overshoot tinggi, settling time lama saat start dan bila terjadi pembebanan kecepatan motor induksi akan turun. Sliding mode control diperkenalkan dengan mengambil keuntungan dari karakteristik switching inverter untuk mengontrol mesin elektrik yang akan menghasilkan overshoot rendah dan settling time yang pendek dengan bentuk transient dan steady state yang baik. Sliding mode control didesain untuk beroperasi melebihi variable yang sama seperti digunakan pada metode DTC. Untuk meningkatkan performa putaran motor induksi pada kondisi ada gangguan, control putaran dengan sliding mode control akan diuraikan, dimana jenis control ini robust pada saat terjadi gangguan dengan variasi parameter dan torsi beban berubah. DTC digunakan sebagai paramater kontrol, untuk mencari torsi, fluks dan sudut yang nantinya akan digunakan sebagai penyulut inverter. Untuk kecepatan diambil dari kecepatan estimator, error dan delta error kecepatan putar sebagai masukan pada SMC. Hasil dari simulasi kondisi berbeban, saat starting overshootnya 83 rad/s, time settlingnya 0.12s dan time risenya 0.02s. Pada kondisi perubahan beban, respon hampir tidak mengalami perubahan kecepatan atau bisa dikatahkan respon kecepatan stabil bila ada gangguan meskipun terdapat osilasi atau ripple.
