Resumo
UTFPR Campus Pato Branco initiated a schedule of implementation of several actions to improve the energy efficiency of the campus in the mold of ISO 50001. The main objectives to be achieved are the reduction of energy costs and conscious consumption of resources. Some actions that are adopted include the replacement of current lamps by more efficient lamps using LED technology and installation of a 378kWp photovoltaic mini-generation system with estimated annual energy production of 581MWh/year. On the other hand, considering the installation of the mini-generation, some problems regarding the quality of electrical energy are expected, such as a possible reduction in power factor and variations in voltage in the internal busbars of the campus. To address these issues, a measurement campaign was initiated on campus to obtain actual data on the university's consumption profile on school and non-school days, as well as the measurement of irradiation in the near region where the mini-generation will be installed. In this work are presented results that were obtained with the insertion of the data measured in simulations, which has as objective to present the main cause effects in the power factor and voltage profile at the point of connection.
