AbstractThe main objective of power electric systems is to provide the necessary energy at a satisfactory quality level. Power networks undergo various alterations through time, and as such its characteristics change along with it when compared to their early states. When dealing with distribution networks, it is important to reassure that those modifications do not harm the network’s voltage level, which can lead to an increase in technical energy losses. In this context, this paper attempts to emulate the power network belonging to the Rio Branco campus of Federal University of Acre, simulating its power flow with the help of a software called SINAPgrid. The adopted methodology involves the use of Geographic referenced coordinates for each power pole belonging to the campus distribution system. The representation of each component that compose the system were made taking into account real characteristics observed on the equipment, such as nominal values for the transformers and measurements recorded with a load analyzer in different locations throughout the university, as to obtain a real reference for the average power factor verified. All the done procedures to use the SINAPgrid software and execute the simulations, testing different scenarios with varying degrees of demand from the transformers, is described along with two possible actions to be taken and their respective outcomes, as to try to improve the voltage and power factor levels in the case studied.
