Abstract

Three-phase load imbalance in power transformers is one of the main problems that can reduce efficiency, increase power losses, accelerate the increase in winding temperature, and reduce the life of transformer insulation. This condition often occurs in distribution systems due to uneven load growth between phases. This study aims to optimize three-phase load balancing to improve the efficiency and reliability of power transformers at the Tanjung Morawa Substation. The research method uses a quantitative approach based on transformer operational data, including measuring the current of each phase, calculating the percentage of load imbalance, analyzing copper losses, and evaluating efficiency and reliability indices. The optimization model is carried out by simulating load redistribution between phases using a mathematical approach to minimize current deviations from the average current. Evaluation parameters include reducing power losses, increasing transformer efficiency, and improving the value of the imbalance factor according to IEC and IEEE standards. The results show that before optimization, the level of load imbalance was in the moderate to high category, which resulted in increased power losses and increased operating temperatures. After the load balancing optimization process, there was a significant decrease in the percentage of imbalance, a decrease in power losses, and an increase in transformer efficiency. Furthermore, the estimated insulation life shows an improvement due to reduced thermal stress. This study demonstrates that a systematic, data-driven three-phase load balancing optimization strategy can sustainably improve the performance, efficiency, and reliability of power transformers. The proposed model can be implemented as part of an asset management and preventive maintenance strategy in electric power systems.

Abstract

Traffic congestion is one of the main challenges in densely populated urban areas. Conventional traffic light systems generally work based on fixed times without considering real conditions in the field. This study aims to design a prototype of an automatic traffic light control system that is able to adjust the turn-on time based on vehicle density. The system uses infrared light-based sensors to detect the number of vehicles on each Line in real-time. The detection data is processed by the ESP32 nodemcu to determine which Line gets the green light first. The system is designed to work alternately and dynamically so that all Lines get a chance, but still prioritizes the most congested Line. Test results show that this system is able to reduce vehicle queues and improve traffic flow

Abstract

Gempa bumi adalah suatu peristiwa alam yang tidak dapat diprediksi kapan dan dimana akan terjadi. Gempa bumi dapat menimbulkan kerusakan di atas permukaan bumi seperti runtuhnya bangunan dan korban manusia. Manusia hanya dapat berusaha untuk mengurangi akibat yang ditimbulkan akibat gempa bumi, seperti membangun bangunan yang tahan gempa, membuat tanda-tanda peringatan dan juga memberikan edukasi tentang gempa bumi dan cara penyelamatan diri. Salah satu upaya manusia untuk mengurangi korban jiwa pada saat gempa bumi adalah dengan membuat alat peringatan dini yang akan mengeluarkan bunyibunyian saat terjadi gempa. Alat peringatan dini ini, ada yang bekerja secara mekanik dan ada juga yang bekerja dengan menggunakan komponen elektronika.

Abstract

Telah dilakukan penelitian tentang studi pengaruh bahan aditif NaCl dan Na-EDTA pada elektrolit baterai berbahan filtrasi air jeruk nipis. Selama ini elektrolit baterai dipakai H2SO4. Karena H2SO4 mengakibatkan gatal-gatal dan luka, bahkan bersifat racun bagi tubuh bila terhirup, maka dalam penelitian dilakukan penggantian elektrolit alternatif yang ramah lingkungan dari nabati yaitu menggunakan filtrasi air jeruk nipis (FAJN). Namun hasil yang didapatkan kurang baik sehingga  dilakukan penambahan bahan aditif larutan NaCl dan Na-EDTA kepada elektrolit FAJN. Hasil penelitian menunjukkan bahwa dengan penambahan bahan aditif ini dapat meningkatkan karakteristik mendekati jenis elektrolit H2SO4, sehingga didapat tegangan yang dihasilkan sampai 7,40 Volt sedangkan elektrolit  FAJN murni saja hanya 6 Volt. Untuk ke depan akan dilanjutkan bagaimana dapat meningkatkan karakteristik elektrolit FAJN sehingga sampai sama dengan elektrolit H2SO4.

Abstract

The 300 kVA Cummins KTA19-G3 generator set is equipped with an advanced electronic control system and protection system managed by the Engine Control Module (ECM), designed to maintain operational stability and prevent fatal damage due to abnormal conditions. This study aims to analyze the performance, response, and accuracy of both systems when the engine experiences disturbances in the form of rotation instability (hunting) and sudden stoppage (shutdown) at a load of 190 kVA (equivalent to 63.3% of maximum capacity). The methods used include measuring operating parameters, reading ECM data history using the Cummins Insite diagnostic tool, and analyzing the system's working logic. The results show that the speed control system (Electronic Governor) works as instructed but fails to stabilize the rotation due to physical obstacles in the fuel and air systems, causing a response delay of up to 1.2 seconds. In contrast, the protection system works very precisely and according to specifications, triggering engine shutdown when it detects rotation deviations exceeding the safe limit of ±6.6% and fuel pressure below the threshold of 1.0 Bar. It was concluded that the operational failure was not caused by damage to the electronic system, but rather by the limitations of the control system in dealing with mechanical disturbances, while the protection system functioned optimally as a last resort.

Abstract

Off-grid Solar Photovoltaic (PV) systems are widely deployed in remote and isolated areas where access to the utility grid is unavailable. However, the reliability of these systems is often compromised by electrical disturbances, including overvoltage, undervoltage, and overcurrent conditions, which may damage inverters and connected electrical loads. This study aims to design, implement, and evaluate the performance of a Digital Adjustable Voltage and Current Protectorfor enhancing the protection of off-grid PV systems. An Adjustable AC Voltage Regulator (Variac) was employed to simulate various voltage conditions under controlled laboratory experiments, while different load levels were applied to assess the system's protection capability. The evaluated parameters included input voltage, output voltage, load current, protection status, and protection response time. Experimental results demonstrate that the proposed protection system effectively disconnects the load under undervoltage conditions at 190 VAC, overvoltage conditions at 240 VAC, and overcurrent conditions exceeding 1.15 A. Furthermore, the protection device exhibits a rapid response time ranging from 0.7 to 0.9 s, ensuring prompt isolation of abnormal operating conditions. The findings indicate that the proposed digital protection system significantly improves the operational safety, reliability, and stability of off-grid PV installations. Therefore, the developed system offers a practical and cost-effective solution for protecting standalone solar power systems, particularly in rural electrification and remote energy applications.

Abstract

This article describes the design of a data system to integrate energy conversion from photovoltaic measurements connected to the power grid. The software used is visual studio, while the hardware uses polycrystalline photovoltaic (PV) with a capacity of 2.08 kW and several sensors that have been integrated into Arduino. Parameter data in measuring the performance of this PV system consists of temperature and humidity sensors to measure the panel surface, direct current (DC) current sensor, DC voltage sensor. To measure the current and voltage sourced from the electricity network, the module (PZEM-004T) is used. Measurements are designed using a graphical user interface (GUI) on a Visual Studio application that has been interfaced through Arduino programming. The data output on the sensor measurement will simultaneously record the circuit that has been connected to the solar panel and then display it visually in the form of tables and graphs in real time with a delay of 1 minute. The results of PV on grid measurements in sunny weather conditions obtained the maximum value of all measurements with a DC voltage of 221 V, while for an alternating current (AC) voltage of 231.60 V, the DC value reached 1827.17 W while the AC power was 1681 W.

Abstract

Currently, the use of solar panels in Indonesia is still in a stationary position (static) so that the absorption of sunlight is less than optimal due to frequent weather, cloudy weather, and during the afternoon until the afternoon the suns light has turn back/or is not parallel to the solar panels. To obtain optimal electrical energy, the solar panel systems must be equipped with a control-systems and equipped with an RTC (Real Time Clock) sensor module which functions to provide real time data/or components to adjust the direction of the surface of the solar panel so that it always faces the sun at a given angle (tracking based on the movement of the earth) so that the energy from the suns ray can completely fall to the surface of the solar panel. And from the data obtained on December 13, 2021, the output produced by a 10 Wp solar panel tracking system for 9 (nine) hours with a 5 Watt lamp load produces a total power of 3.392 Wh while a non-tracking 10 Wp solar panel produces a total power of 19.658 Wh and the difference between the two 10 Wp solar panels is 15.732 Wh.

Abstract

As electric vehicles (EVs) continue to gain global popularity, residential photovoltaic (PV) charging stations are becoming more common, providing a sustainable way to charge EVs. However, the intermittent nature of solar energy creates challenges in ensuring consistent and fair charging, making fairness-based charging scheduling essential. To automate this process, residential PV charging stations require a customized Internet of Things (IoT) system. A significant concern is the substantial energy consumption due to the high volume of data transmission within the IoT system. This research aims to enhance energy efficiency by leveraging green IoT strategies suitable for such applications. The study proposes the use of edge computing, optimized data transmission scheduling, and delta compression techniques at the edge to minimize energy use. The results demonstrate that these strategies are effective in achieving energy savings. Energy-saving efficiency on the source side ranges from 1.96% to 7.84%, while on the load side, it ranges from 57.5% to 61.3%. These findings highlight the effectiveness of the proposed strategies in reducing energy consumption, providing an efficient solution for optimizing data transmission in residential PV charging stations. Overall, the strategies contribute to the sustainable operation of electric vehicle charging infrastructure by improving energy efficiency and ensuring fair distribution of charging resources.
