Abstract

Pengunaan Peralatan listrik skala rumah tangga, perusahan dan industri besar dalam menjalankan kegiatan sehari-hari. Namun peralatan ini termasuk jenis beban non linier seperti mesin-mesin industri, peralatan elektronik, dan perangkat lainnya. Beban non linier menimbulkan arus harmonik pada gelombang arus listrik, yang mengakibatkan gelombang arusnya tidak lagi sinusoidal murni dan penurunan faktor daya. Hal ini dapat menurunkan kinerja peralatan listrik dan menaikkan suhu peralatan listrik sehingga peralatannya panas dan rusak dan pendek umurnya. Oleh karena itu, salah satu cara untuk mengatasi permasalahan ini adalah filter daya aktif mengunakan kontrol arus ramp comparison current control untuk dapat mereduksi arus harmonik pada gelombang arus listrik sehingga dapat berbentuk sinusoidal murni dan menaikkan penurunan power factor. Dalam penelitian ini, penulis memfokuskan kepada filter daya aktif mengunakan kontrol arus ramp comparison current control untuk mengurangi arus harmonik sehingga kualitas daya listrik yang baik dalam sistem tenaga listrik dan dapat berbentuk gelombang sinusoidal. Model dirancang, pembuatan model, disimulasikan dan dianalisa dengan menggunakan software PSIM. Dari hasil simulasi dan analisa dapat diperlihatkan bahwa sistem tanpa filter daya listrik menghasilkan tingkat THD arus sebesar 27% dan nilai power factor 0,79 sedangkan sistem filter daya aktif mengunakan metode kontrol arus ramp comparison current control menghasilkan tingkat THD arus sebesar 4% dan nilai power factor 0,96

Review

This paper presents a simulation-based investigation into the application of an active power filter (APF) utilizing Ramp Comparison Current Control to mitigate Total Harmonic Distortion (THD) and improve the power factor in electrical power systems. The authors correctly identify the pervasive issue of non-linear loads in modern electrical systems, ranging from household appliances to industrial machinery, which introduce harmonic currents. These harmonics distort the sinusoidal current waveform, leading to reduced power quality, lower power factors, decreased equipment performance, increased operating temperatures, and ultimately, a shortened lifespan for electrical devices. The primary objective of this study is to demonstrate the effectiveness of the proposed APF and control strategy in restoring a pure sinusoidal current waveform and enhancing the power factor. The methodology employed in this research involves the design, modeling, simulation, and analysis of the active power filter system using PSIM software. The study provides clear quantitative results that underscore the efficacy of the proposed solution. Without the active power filter, the system exhibited a significant current THD of 27% and a power factor of 0.79, indicating substantial power quality issues. In contrast, the implementation of the active power filter incorporating the Ramp Comparison Current Control method dramatically improved these metrics, reducing the current THD to a commendable 4% and elevating the power factor to an impressive 0.96. These simulation results strongly suggest that the active power filter with this control strategy is highly effective in achieving the desired power quality improvements. While the simulation results are promising and clearly demonstrate the potential of the active power filter with Ramp Comparison Current Control, the review would benefit from a more detailed discussion on the selection of this particular control strategy compared to other common methods (e.g., hysteresis, dead-beat, or predictive control). Future work could extend this research by validating the simulation findings through experimental prototypes, which would provide crucial real-world applicability and insights into practical implementation challenges such as system stability, cost-effectiveness, and robustness under varying load conditions. Nevertheless, this paper makes a valuable contribution by highlighting an effective approach to enhancing power quality, which is crucial for the reliable and efficient operation of modern electrical grids.
