Selección de filtros pasivos en DIgSILENT para la mitigación de corrientes reactivas de acuerdo con el informe de calidad de energía realizado en un transformador de 2000 KVA

Abstract

The work presented with the title “Selection of passive filters in digsilent for reactive currents mitigation according to the power quality report performed in a 2000 kva transformer” simulates a passive filter in DigSILENT Power Factory software. The objective of this filter is to mitigate the reactive currents shown in the power quality analysis, reducing the cost of electric bills and guaranteeing a cleaner energy. This project arises from the urgent need to ensure the integrity and optimal operation of electrical equipment, which is constantly threatened by power quality problems associated with the presence of harmonics. Among the most common consequences of this phenomenon are low power factor, generation of stray currents and untimely disconnection of capacitor banks. In order to mitigate these adverse effects, the implementation of passive filters is proposed, which have proven to be an effective solution for the control and elimination of harmonics, thus allowing to significantly improve the quality of the power supplied. During its development, a power quality analysis is performed in the field in order to observe the behavior of harmonics without a passive filter included. A selection of the passive filter is also made through a simulation that allows to study the behavior of the harmonics indicators with a filter. In addition, we study how the different electrical parameters are affected by stray currents and propose the use of the passive filter in order to have a higher energy quality. Using specialized DigSILENT software and PowerVisionPlus electrical data visualization software, the electrical system will be modeled based on power quality analysis to analyze in depth the behavior of harmonics.The results of these simulations will serve as a basis for designing practical and efficient solutions, such as harmonic control systems, which will benefit the industry and the professional community. This project represents a relevant contribution to the field of electrical engineering, since it focuses on the appropriate selection of passive filters to improve power quality in electrical distribution networks. Through a technical and comparative analysis, it seeks to identify the most effective filters to mitigate harmonic disturbances and ensure a stable and reliable operation of the system.
