Teoria da Potência Conservativa Aplicada ao Compartilhamento de Responsabilidades Devido às Distorções Harmônicas de Tensão: Considerações e Estudo de Casos

Abstract

The insertion of equipment with nonlinear characteristics in the electrical system has increased exponentially in the last decades. It is known that despite the benefits of such technological advances, there is the possibility of power quality degradation. In this context, when the limits of harmonic distortions are above the maximum allowed in the regulations, the concern of sharing responsibility among the agents involved in this deterioration of power quality arises, indicating, consequently, the financial division of possible mitigating actions. Therefore, this paper aims to compare the Conservative Power Theory (CPT), in the scenario of responsibility sharing due to voltage harmonic distortions, with the Superposition method. It is important to highlight that the Superposition of Voltages methodology, presents itself as a template for the study of other methods. To fulfill the proposed objective, the MATLAB/Simulink computational tool will be used. In the present work, four cases will be evaluated.
