Abstract

Geothermal Power Plant (PLTP) is a renewable energy source that has great potential to meet electricity needs in a sustainable manner with low carbon emissions. This research aims to develop mathematical models and Matlab-based control systems to increase the power capacity of geothermal power plants. The system model includes reservoir dynamics, production wells, turbines, and generators with control using the PID (Proportional-Integral-Derivative) method. Simulations were conducted to test the system response to variations in electrical load, reservoir temperature, and operational disturbances. The simulation results show that the PID control successfully maintains the electrical power output to be close to the reference value with a fast response despite the presence of overshoot and initial oscillation. Adjustment of PID parameters is recommended to reduce overshoot and accelerate stabilisation of power output. This research contributes to the optimisation of geothermal power plant operation so as to improve efficiency and national energy security based on geothermal energy.

Abstract

This study explores the optimisation of light intensity on solar cells to improve their energy efficiency. With the increasing global demand for energy and environmental issues due to dependence on fossil fuels, renewable energy sources, particularly solar energy, have become important. However, the efficiency of solar cells remains a challenge, with typical commercial efficiency ranging from 15% to 22%. This research investigates the impact of light intensity on solar cell performance and identifies strategies to optimise it. Factors such as semiconductor material quality, panel angle and orientation, and external conditions like weather and pollution are considered. The study shows that optimising light intensity can significantly enhance the energy conversion efficiency of solar cells. Methods such as using mirrors to concentrate sunlight and adjusting panel positions are explored to maximise light intensity. These findings contribute to the development of more efficient solar cell technology, aiding the broader adoption of clean energy solutions.

Abstract

This research analyzes the efficiency comparison between the Auxiliary Power Unit (APU) and Ground Power Unit (GPU) on the Airbus A320 aircraft's electrical system during ground operations. Aircraft operations require a stable power supply, provided by either an internal APU or an external GPU. Although the APU offers flexibility, its high fuel consumption and significant environmental impact are considerable concerns. Conversely, the GPU is deemed more efficient and environmentally friendly. The study aims to calculate energy consumption, analyze efficiency, and recommend the most efficient and environmentally sound electrical power source. The method employed is a quasi-experimental field observation, involving direct data collection from a Houchin LTD model C690 GPU unit. Data collection was conducted over 7 days, from June 1 to June 7, 2025. Data analysis includes mathematical calculations for energy efficiency and operational economic analysis. Research findings indicate that the GPU significantly outperforms the APU. The diesel GPU exhibits an energy efficiency of approximately 31.30%, considerably higher than the APU's around 1.54% (based on 7 days of data). The GPU also presents superior electrical power quality, characterized by a higher Power Factor and lower Total Harmonic Distortion (THD). It is recommended that airlines prioritize GPU usage, and airport authorities expand Fixed Electrical Ground Power (FEGP) infrastructure to enhance energy efficiency and reduce operational costs.

Abstract

Switched Reluctance Generators (SRGs) have attracted attention due to their robust construction, low cost, and high fault tolerance, suitable for extreme environments. However, SRGs suffer from torque ripple and acoustic noise due to the non-linear torque-excitation current relationship. Although SRG component optimization has been investigated, a gap exists in the analysis of the effect of stator excitation current on the drive torque in a single-phase "6/6" SRG design with external amplification. This study analyzes the impact of varying stator excitation current on the drive torque of a single-phase 6/6 SRG. The methodology includes design, finite element analysis (FEA), and testing of an initial drive torque prototype. Results show that increasing the stator coil supply voltage results in a greater magnetic force, which counteracts the mechanical torque on the rotor shaft. This understanding is crucial for optimizing torque performance, mitigating ripple, and improving SRG efficiency for future applications.

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.
