Intensitas radiasi diperoleh dari sensor Solar Power Meter menggunakan interface kabel RS232 to TTL. Hasil menunjukan nilai rata-rata error tegangan sebesar 36 mV atau inakurasi 0,41% untuk rentang pengukuran dari 0,7 V sampai 24 V, sedangkan rata-rata error arus sebesar 10 mA atau inakurasi 0,42% untuk pengukuran dari 0,3 A sampai 7,5 A. Nilai inakurasi ini masih dibawah nilai rata-rata alat ukur standar yang ada di pasaran sekitar 1%, sehingga hasil rancangan ini bisa digunakan untuk keperluan pengukuran.Kata kunci: tegangan, arus, daya, iradiasi matahari, Arduino ABSTRACTInformation about the output power of solar panels and the intensity of solar radiation are needed in the PV system to determine the characteristics of the power generated by the panel and the estimated amount of installed load. In this research, an Arduino-based data logger has been designed with a MicroSD card data storage media and a MS Excel data format. Power parameters are obtained using a voltage sensor module with the principle of a voltage divider and a current sensor with a shunt resistor. The radiation intensity is obtained from the Solar Power Meter sensor using a RS232 to TTL cable interface. The results show the average of voltage error is 36 mV or inaccuracy is 0.41% for the measurement range from 0.7 V to 24 V, while the average of current error is 10 mA or inaccuracy is 0.42% for the measurement from 0.3 A to 7.5 A. This inaccuracy value is still below the average value of standard measurement tools on the market about 1%, so the results of this design can be used for the purpose of measurements.Keywords: voltage, current, power, solar irradiation, Arduino

Abstract

One of the main challenges in building a Solar Power Generation System at home or a Home Solar Power Plant (Home SPP) is choosing component specifications according to price. The main components of Home SPP are photovoltaics (PV) panels, inverters, and wiring systems. Given the strict price constraints, the selection of parts available on the commercial market is generally of low quality. However, low-quality components can still provide a significant advantage by optimizing the plant design. This research proves that the proper configuration can reduce electricity bills by 52.2%. This configuration does by choosing a Grid Tie Inverter (GTI) with a high working voltage and a 12 Volt PV configured in a parallel series circuit to work at 24 Volts. In addition, the 12 Volt PV panels configured in series to 24 Volts are proven to increase the conversion efficiency.

Abstract

Pada PLTU, temperatur Main steam atau uap yang menuju High Pressure Turbine sering kali mengalami kenaikan melebihi batas normal operasi, umumnya sebesar 538oC. Hal ini dapat menyebabkan penurunan umur sudu turbin akibat dari creep fatigue pada materialnya. Kenaikan suhu ini umumnya disebabkan oleh terjadinya trip pada coal feeder dan pulverizer, atau mungkin juga disebabkan oleh faktor yang tidak diketahui dengan pasti, seperti adanya slagging. Meskipun telah ada komponen pengatur temperatur Main steam (Attemperator) untuk menstabilkan suhu pada setpoint, namun pada beberapa kondisi masih sulit untuk menstabilkan fluktuasi yang ekstrim. Untuk mengatasi masalah ini, dilakukan penambahan sistem desuperheater pada outlet boiler dengan kapasitas 60 ton/jam. Sistem desuperheater ini berhasil menurunkan suhu Main steam dari titik tertingginya, yaitu sekitar 565oC, menjadi stabil kembali pada setpoint yang diinginkan. Pengendalian suhu berhasil dilakukan melalui kontrol PID konvensional berdasarkan hasil simulasi menggunakan perangkat lunak Simulink. Berdasarkan hasil tuning menggunakan perangkat lunak Simulink, konstanta PID yang digunakan adalah P = -23.5, I = -2.8, D = -40.9, dan N = 1.9. Simulasi menunjukkan bahwa penambahan sistem desuperheater dengan kontrol PID berhasil menjaga suhu Main steam tetap stabil pada setpoint.

Abstract

The use of abundant solar energy in Indonesia is a concern for the government, especially for areas that are still not electrified by the PLN cable network. The conversion of solar energy to electrical energy is carried out using PV solar panels to form a solar power plant (PLTS). The existence of this PLTS is increasing throughout Indonesia so that it takes human resources who have these competencies to manage it. With this awareness, the Community Service Activity (PKM) program of the Department of Energy Conversion Engineering at the Bandung State Polytechnic invites a partner at SMKN 1 Cimahi to jointly equip its students to get a PLTS competency briefing. One of the competencies developed is about the installation of the solar power plant electrical system. This activity was held during the very dangerous Covid-19 virus pandemic which forced people to work at home (WFH). However, instead of being an obstacle, it provides an appreciable result, namely the gain of experience to develop learning modules that can be delivered online. The analysis of the results of the PKM implementation proved that one way of providing knowledge on the aspect of knowledge can be held online.

Abstract

Large motors often burden synchronous generators as power plants in factories. This motor is commonly using to regulate rotation using Variable Speed Drive (VSD). From the load side, VSD, as a regulator of motor rotation, can reduce power loss. On the generator side as a power plant, this load with VSD affects the waveform of the generator. The experiments on a small capacity generator (6 kVA) with a VSD as regulating the motor rotation with a load of about 1.1 kW shows effectiveness power transfer is about 40.7% with VSD, and without VSD, efficiency is approximately 39.6%. The motor losses by installing VSD interpreted as transferring losses to the generator with savings is about 1 %. The experiments also showed that generator performance decreases when loaded with VSD at around 6%, and a generator temperature increases at 20 0C higher than without VSD.

Abstract

Electrical energy obtained from renewable resources is usually in the form of direct voltage (DC). In comparison, most household and industrial appliances operate using alternating voltage (AC). To connect renewable resources with appliances that require AC, a device that can convert DC voltage to AC is required, known as an inverter. This research focuses on the development of a three phase inverter ignition module with 60 Degrees Pulse Width Modulation (PWM) switching technique. The module uses analog signal processing to adjust the signal and a microcontroller to regulate the voltage generation variables. The work starts from the design stage to the data collection stage of the ignition signal output. The developed module produces six 60-degree PWM signals with a reference frequency of 50 Hz and a carrier frequency of 900 Hz, and a working voltage of 5 volts. The system accuracy was assessed with a reference frequency error of 0.8% and a carrier frequency error of 2.06%.This research shows that the use of the 60-degree PWM technique can result in efficient conversion, making it an effective solution for three-phase inverter applications
