Item Acesso aberto (Open Access) Cálculo de perdas técnicas e não técnicas nas redes de distribuição de energia elétrica usando a definição de impedância equivalente de perdas(Universidade Federal do Pará, 2018-10-17) PAYE, Juan Carlos Huaquisaca; BEZERRA, Ubiratan Holanda; http://lattes.cnpq.br/6542769654042813This work presents a new concept called Loss Equivalent Impedance (LEI), which is characterized by being a practical and economical method that allows calculating technical and non-technical losses in electricity distribution networks with good accuracy, for which it uses the data that any electric utility has, such as the user's electricity bills, the grid's electrical parameters and the measurements of power and currents at the substation coupling point. To show the application of this method, this document covers the data processing and description of the software used to simulate the operation in the test systems IEEE 13 and 37 buses networks, considering that they present technical and non-technical losses. In addition, these systems are evaluated with different operational conditions, including the incorporation of a photovoltaic plant. The cases evaluated in this work show that the method can be used to plan and monitor the electricity distribution networks, considering the separation of technical and non-technical losses, so that in future reduction actions concerning these losses can be managed, since of unmanaged electricity losses is translated into considerable economic losses for both the utility and customers and indirectly for the country. The results presented in this dissertation, regarding the application of the Equivalent Operational Impedance to the calculation of technical and non-technical losses, have demonstrated the effectiveness of the proposed methodology, so that it is foreseen a great potential for the application of the proposed procedure in the electrical sector mainly in the distribution utilities.
