Abstract

Pembangkit listrik tenaga surya (PLTS) menghasilkan tegangan listrik dari solar cell yang terkena paparan sinar matahari. Tinggi rendahnya tegangan yang dihasilkan adalah tergantung dari banyak sedikitnya sinar matahari yang mengenai panel solar cell. Bayangan yang menutupi solar cell dari sinar matahari secara langsung telah diteliti akan mengakibatkan penuruan tegangan keluaran secara drastis. Panel solar cell yang tertutup tidak akan bekerja sehingga akan mengurangi tegangan keluaran secara keseluruahan pada bagian yang tertutup tersebut. Namun demikian lapisan film yang menutupi panel solar cell tidak menutup cahaya matahari secara keseluruahn, akan tetapi mengurangi unsur sinar matahari yang sampai ke solar cell. Cahaya matahari tetap sampai tetapi unsur panas yang berkurang setelah melewati filter. Memalui penelitian ini diperoleh hasil tegangan akan tetap dihasilkan tetapi terdapat perbedaan dengan hasil paparan matahari secara langsung. Filter yang digunakan tidak hanya mengurangi panas pada solar cell jenis polycrystalline tetapi juga penurunan tegangan keluaran namun tidak terlalu besar. Manfaat tabir ini lebih besar pada penurunan suhu permukaan solar cell.

Abstract

This study presents a comprehensive analysis of the dielectric quality of a 60 MVA power transformer at the Kisaran 150kV Substation, North Sumatra, Indonesia. The transformer, manufactured by PAUWELS TRAFO and operated since 2011, operates at an average load of 33% with an ONAN/ONAF cooling system. Dielectric testing yielded a breakdown voltage of 80.2 kV, a moisture content of 17.62 mg/kg, an acid number of 0.108 mgKOH/g, and dissipation factors of 0.173% (primary), 0.190% (secondary), and 0.243% (tertiary). The bushing dissipation factor ranged from 0.247% to 0.271%. The interfacial tension measured 26.8 mN/m with a flash point at 148°C. Insulation resistance testing showed values of 4.9 GΩ (primary), 3.41 GΩ (secondary), and 3.40 GΩ (tertiary) with polarization indices of 3.06, 1.48, and 1.47, respectively. Operating temperatures remained within acceptable limits at 63°C (peak oil) and 62°C (winding). Analysis based on IEC 60422:2013 and PLN standards indicated that the transformer was in good operational condition with all parameters within acceptable ranges, although the interface voltage was close to the warning threshold. This study provides valuable baseline data for predictive maintenance strategies and demonstrates the importance of integrated dielectric testing for transformer health assessment.

Abstract

Single line-to-ground faults are among the most frequently occurring disturbances in high-voltage transmission systems and are strongly influenced by the sensitivity settings of the Ground Fault Relay (GFR). This study aims to analyze the suitability of ground fault relay settings in response to short-circuit faults in the 150 kV transmission system at Paya Pasir Substation. The research method involves evaluating existing relay settings on feeder bays, bus couplers, and power transformers, then comparing them with calculation standards based on 7% of the smallest short-circuit capacity (CCC). To obtain optimal relay settings, power system simulations were conducted using ETAP version 19.0.1 by modeling the network in a single-line diagram and analyzing single line-to-ground faults. The results show that most existing GFR settings do not meet protection sensitivity standards, with 60% of feeder bay settings classified as unsuitable. After ETAP simulation and protection parameter adjustments, improved relay sensitivity and selectivity were achieved, ensuring proper protection coordination among feeders, busbars, and power transformers. Therefore, ETAP simulation is proven to be an effective tool for evaluating and optimizing ground fault relay settings in a 150 kV transmission system.

Abstract

The grounding system is an important part of maintaining the safety and reliability of electrical power transmission systems, especially in high-voltage transmission towers. In transmission towers, the grounding system functions to safely conduct fault currents caused by lightning strikes or short circuits to the ground. This study aims to analyze the grounding system of a 70 kV transmission tower using the Mesh Grid Grounding System (MGGS) method on Tower T.213 of the Pekalongan - Sukamerindu line. The research method used is a quantitative method with a technical analysis approach, namely calculating the grounding resistance of the grid system, the ground rod system, and the total MGGS grounding resistance based on field data. The data used included soil resistivity of 48.7 Ωm, grid conductor length of 66 m, grid area of 36 m², conductor planting depth of 1 m, and the use of 20 ground rods with a length of 2 m. The calculation results were then compared with the field measurement results to determine the reliability level of the grounding system. The results of the study show that the initial grounding resistance value of 8.46 Ω can be reduced to 4.46 Ω after applying the MGGS method. The reduction in grounding resistance value reached 47.3%, indicating that the MGGS method is effective in improving the performance of the tower grounding system. Based on an evaluation of the IEEE Std 80 standard, the final grounding resistance value obtained was still below the recommended maximum limit, so the grounding system of Tower T.213 was declared safe and suitable for use. Thus, the application of the Mesh Grid Grounding System (MGGS) method has been proven to improve the reliability and safety of the grounding system on 70 kV transmission towers.

Abstract

This study analyzes the electrical energy requirements of the Optical Line Terminal (OLT) transmission room at the Telkom Tanjung Morawa Office using a load forecasting approach based on historical data for the 2021–2023 period. This applied research uses a descriptive-analytical quantitative approach and compares three forecasting methods, namely Linear Regression, Double Exponential Smoothing (DES), and ARIMA, which are validated using MAE, RMSE, and MAPE. The results show that energy consumption increased from 555,000 kWh in 2021 to 670,800 kWh in 2023, with an average annual growth of 9.9%. The ARIMA(2,1,1) model provides the best accuracy with a MAPE of 3.9%, compared with DES at 6.8% and Linear Regression at 11.4%. The projected energy requirements for 2024–2026 are 733,800 kWh, 804,000 kWh, and 878,400 kWh, respectively. The estimated peak load is projected to exceed the safe utilization threshold of 80% of the installed capacity of 135 kW by mid-2025. These results indicate the need to plan an increase in electrical system capacity before that period to maintain the operational reliability of the OLT transmission room
