Abstract

The rapid advancement of power system technologies has significantly transformed the way electrical power quality (PQ) is monitored, managed, and improved. The increasing penetration of non-linear loads, automation systems, and renewable energy sources has intensified power quality challenges, including harmonic distortion, voltage sags, voltage fluctuations, and transient disturbances. This study aims to analyze the impact of modern technological approaches on power quality enhancement in contemporary power systems. A descriptive-analytical research methodology was employed through a systematic review of recent scientific literature, international standards, and technical reports related to power quality management. The collected data were analyzed using qualitative content analysis and comparative evaluation to assess the effectiveness of automation, machine learning, Internet of Things (IoT)-based monitoring systems, and power electronic mitigation devices. The results indicate that integrated technological solutions significantly improve power quality performance compared to conventional approaches. Machine learning techniques, particularly Artificial Neural Networks, demonstrate high accuracy in disturbance classification and adaptive control, while IoT-based systems enable real-time monitoring and rapid response to power quality deviations. Furthermore, power electronic devices such as Active Power Filters, Static Var Compensators, and Dynamic Voltage Restorers effectively mitigate harmonics and stabilize voltage. However, challenges related to implementation cost, system complexity, cybersecurity, and regulatory inconsistency remain. The study concludes that an integrated, intelligent, and data-driven framework is essential for sustainable power quality management in modern power systems.

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.

Abstract

Temperature increase in solar panels is one of the main factors that reduces energy conversion efficiency in Solar Power Plant systems. To address this issue, fluid-based cooling methods have become an effective alternative in maintaining panel performance stability. This study analyzes the performance comparison of cooling systems using freshwater and saltwater on panel temperature changes and their effects on power output efficiency. The experimental method was conducted by operating solar panels under the same solar radiation conditions, then applying two types of cooling fluids separately to observe differences in temperature reduction and electrical performance improvement. The analysis results show that both cooling methods can significantly reduce panel temperature, but there are differences in thermal characteristics between them. Cooling using saltwater demonstrates better heat transfer capability, but potentially causes corrosion effects in the long term. Meanwhile, freshwater provides quite effective cooling stability with lower damage risk. These findings provide a comprehensive overview regarding the selection of optimal cooling media to enhance PV system efficiency in tropical conditions.

Sistem distribusi tenaga listrik sering menghadapi tantangan operasional signifikan pada jaringan tegangan rendah, terutama di wilayah dengan karakteristik panjang saluran besar, konduktor berpenampang terbatas, dan ketidakseimbangan beban antar fasa. Di ULP Tebing Tinggi, fenomena jatuh tegangan tinggi tercatat di ujung feeder jauh dari gardu utama, sementara rugi daya akibat aliran arus dan resistansi saluran menjadi beban biaya dan teknis bagi penyedia layanan. Penelitian ini menggunakan pendekatan kuantitatif berbasis analisis teknis yang menggabungkan pengukuran lapangan, perhitungan matematis, dan simulasi sistem tenaga menggunakan software ETAP. Pengukuran menunjukkan beban total gardu TT38 mencapai 91,69 kVA dengan ketidakseimbangan arus yang signifikan. Tegangan di ujung jaringan mengalami penurunan drastis menjadi 184 V dari tegangan pangkal 222-228 V, dengan jatuh tegangan sebesar 25,26% dan rugi daya 14,94 kW. Skenario uprating konduktor dengan mengganti kabel TIC 2×10 mm² menjadi TIC 3×70+1×50 mm² pada segmen 250 meter terakhir menunjukkan peningkatan signifikan. Hasil perhitungan dan simulasi ETAP konsisten menunjukkan penurunan jatuh tegangan dari 25,26% menjadi 3,61% (202,24 V) dan pengurangan rugi daya dari 14,94 kW menjadi 12,37 kW. Perbaikan ini berhasil membawa tegangan minimum ke dalam batas standar SPLN (198-231 V) yang sebelumnya tidak terpenuhi.

Abstract

Drying clothes is a process of daily activities. Drying clothes through the drying process is a traditional method that is still widely used in various regions. However, the process of drying traditional clothes is often a challenge for people or individuals who have limited space and time, especially if the drying is done at home while at the same time not at home. So it takes innovation of smart clothesline devices based on the Internet of Things (IoT) that can help optimize the drying process of clothes. In designing and manufacturing this automatic clothes drying system uses two sensors, namely water sensors and light sensors. Both of these sensors function as weather detectors. If it rains, the water sensor will respond by sending voltage to the circuit and then moving the servo motor to rotate to the right or left so as to make the clothesline enter a closed room. When the clothesline enters, Arduino will give a command to the GSM module SIM800L to give a notification in the form of an sms that the clothesline has been inserted. Similarly, with the light sensor, when the rain has stopped, the light sensor responds to sunlight so that it makes the servo motor move to remove the clothesline.
