Avaliação Computacional e Aplicação em Campo do Método do Chaveamento de Capacitores para o Compartilhamento de Responsabilidades Harmônicas

Despite the importance of keeping harmonic distortion levels below appropriate limits, no technical standards have established methodologies for sharing harmonic responsibilities. Several studies have already been carried out to propose and evaluate methods for achieving this goal. However, the most accepted method in the literature presents difficulties in its practical implementation. Therefore, efforts have been made to propose effective and feasible methodologies for application in the field. In this sense, the Capacitor Switching Method (MCC) stands out, as it does not require the knowledge of harmonic impedances and can be done using capacitor banks that exist in the installation. Therefore, this work aims to extend the studies and practical applications of the MCC. In this way, first, the IEEE-BTS-HCD reference test system simulated in MATLAB/Simulink is used to evaluate the rated power limit of the connecting capacitor bank, which still provides assertive results for the MCC. Next, we move on to the field application of this methodology in a shopping center in Uberlândia/MG, demonstrating the feasibility of applying the method in the field and verifying the results.
