Abstract

Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh luas permukaan isolator yang terkontaminasi lumut terhadap arus bocor pada string isolator 150 kV saluran transmisi Koto Panjang – Payakumbuh. Variabel yang digunakan dalam perhitungan pengujjian yaitu nilai ESDD, NSDD dan luas permukaan isolator yang terkontaminasi. Hasil penelitian menunjukkan bahwa ESDD, NSDD dan luas permukaan memiliki pengaruh yang signifikan dalam menyebabkan arus bocor pada isolator. Berdasarkan hasil dari perhitungan dan eksperimen yang dilakukan menunjukkan bahwa pada nilai ESDD 0,392300 mg/ ,NSDD 0,633148 mg/cm², Dan luas permukaan isolator yang terkontaminasi 39,074 Maka dalam kondisi ini dapat disimpulkan bahwa arus bocor memiliki hubungan berbanding lurus dengan ketiga variabel tersebut. Ketika nilai ESDD, NSDD, atau luas permukaan yang terkontaminasi meningkat, sehingga arus bocor juga akan meningkat secara proporsional. Hubungan ini menggambarkan bahwa setiap peningkatan dalam salah satu dari ketiga variabel tersebut akan menghasilkan peningkatan arus bocor yang lebih besar, sehingga memahami dan mengelola kontaminasi menjadi sangat penting untuk menjaga kinerja isolator dan keandalan sistem transmisi.

Abstract

Saluran transmisi 150 kV Koto Panjang – Payakumbuh di Sumatera Barat sering terganggu akibat sambaran petir karena tingginya kepadatan petir di wilayah tersebut. Flashover pada isolator, baik akibat polusi maupun kondisi ekstrem di lingkungan, dapat memicu terjadinya arus bocor sehingga menurunkan daya tahan dielektrik dan mempengaruhi kinerja jaringan. Penelitian ini menganalisis pengaruh arus bocor terhadap daya tahan dielektrik pada isolator bersih yang mengalami flashover, menggunakan metode Hileman dengan memasukkan nilai ESDD, NSDD, dan data eksperimen dari laboratorium tegangan tinggi UGM. Hasil penelitian ini menunjukkan peningkatan arus bocor menurunkan daya tahan dielektrik; penurunan terbesar daya tahan dielektrik berdasarkan eksperimen adalah 0,95% dari nilai standar BIL ketika arus bocor meningkat 12,56%, sementara metode Hileman memprediksi penurunan 0,92% ketika peningkatan arus bocor sebesar 11,98%. Studi ini menggarisbawahi pentingnya perbaikan desain dan pemeliharaan isolator serta strategi mitigasi untuk meningkatkan keandalan jaringan di wilayah rawan petir.

Abstract

Measuring electrical energy is an important matter between PLN and its customers. For this reason, PLN uses kWh meters as a tool to measure energy usage for customers. However, the kWh meter used must not only be able to measure, but must also be accurate, precise and easy. Especially for large customers, where special attention is needed for the use of electrical energy. For this reason, PLN has implemented electronic meters that have been installed with the AMR system for large customers. This is intended so that historical electricity usage for large customers can be recorded and monitored properly. Apart from that, the AMR system is also useful as an early detection of abnormalities in electronic meters for large customers by analyzing the data obtained. Through this data, DLPD (List of Subscriptions Needing Attention) can be determined so that customers who experience problems with their electronic meters can be monitored. With this DLPD feature, it really helps PLN employees in analyzing and evaluating the disturbances that occur. Keywords: Automatic Meter Reading, Electronic Meter, DLPD, AMICON

Abstract

Voltage and frequency quality are paramount in 20 kV distribution systems that supply both medium and low voltage feeders. This study explores the significant voltage deficiency in the Maroko Tapung extension of PT PLN (PERSERO), ULP Duri, which dropped 16% from the nominal value. The main objective is to implement a comprehensive voltage restoration strategy to improve the efficiency of the 20 kV distribution system so that it reaches a better standard. The restoration was carried out by setting tap changers, installing shunt capacitor banks, and gradually increasing the tap settings on distribution transformers. Simulation results show a significant improvement in the minimum voltage level across the network, with the lowest voltage on the medium voltage side increasing to 91.69% and on the low voltage side to 90.47%. These outcomes demonstrate that the implemented multi-stage restoration procedures effectively brought the voltage quality within the acceptable limits defined by SPLN 1: 1987 standards, which permit a deviation of +5% and -10% from the nominal voltage. This study highlights the effectiveness of combined tap adjustments and shunt capacitor installation in mitigating voltage drops and ensuring compliance with regulatory standards in distribution systems.

Abstract

The potential for solar energy is immense, as the sun is an abundant source of renewable energy worldwide, especially in Indonesia. Indonesia receives sunlight for 10 to 12 hours per day. Numerous studies on the use of solar power plants have shown promising payback period results less than 10 years which is relatively fast compared to the economic lifespan of solar panels, which can last up to 25 years. PT Bank Nagari, a bank owned by the Provincial Government of West Sumatra and various regional governments within West Sumatra, consistently promotes a culture of efficiency to enhance revenue and support the company’s growth and regional development. Considering the fast capital return on solar power investments and the alignment with Bank Nagari's culture of efficiency and revenue optimization, a feasibility study was deemed necessary. This study aimed to analyze the feasibility of using a solar power plant at Bank Nagari Lubuk Gadang Branch using investment feasibility methods to determine whether the project could enhance the company's efficiency and revenue. However, the research concluded that the investment in the solar power plant was not feasible, as the returns were lower compared to the current business activities run by PT Bank Nagari Lubuk Gadang Branch.

Abstract

Solar Power Plants (SPP) are one of the main solutions in the utilisation of renewable energy. However, their efficiency is often hampered by the variability of solar radiation and ambient temperature. To overcome this, Maximum Power Point Tracking (MPPT) technology is required so that solar panels always operate at the maximum power point (MPP). This study develops a Mamdani fuzzy logic-based MPPT system using MATLAB Simulink on a 10 WP PLTS prototype. The fuzzy algorithm is designed with two inputs, namely power and voltage, and one output in the form of a PWM signal to regulate energy conversion efficiency. Five test scenarios were conducted with different input combinations to compare the results of MATLAB simulations and manual calculations using the centroid weighted average method. The results show that the difference between simulation and manual calculations ranges from 1 to 11 PWM units (average <5%), with output classification remaining consistent in the Low, Medium, and High categories. This demonstrates that the Mamdani fuzzy manual method is valid and reliable as an adaptive control solution for PLTS systems. This implementation is expected to significantly improve energy conversion efficiency and support the achievement of national clean energy targets.

Abstract

Because of its sturdy design, affordability, and convenience of use, the three phase induction motor is a common kind of electric motor, especially in the industrial sector. This motor design is still being improved to make it work better. For example, permanent magnets are being added to the rotor, control systems are getting better, the number of phases is being increased, and motor winding designs are developing. Nevertheless, the creation of the motor winding design is the least expensive aspect of all these endeavors. By creating a nine-phase winding configuration with a three-layer design in the motor, this study aims to enhance the performance of a three-phase induction motor. This study examined output power, speed, mechanical torque, and motor efficiency in a 3-phase system operation. The study's results indicated that the new design motor worked better, with higher output power (4.27%), rotor speed (0.61%), and mechanical torque (3.47%), despite a minor reduction in efficiency relative to conventional 3-phase induction motors (-0.24%).
