| Resumo: | This dissertation aims to evaluate the impacts on the quality of electrical energy (QEE) due to the insertion of distributed generation in the electrical grid. PQ requirements are defined by government agencies. Violation of these indices can lead to losses for final consumers and also for energy concessionaires. It can be highlighted as the main problems due to excess distributed generation being overvoltage and overload in the network that can cause burnouts and malfunction of equipment connected to the electrical system. There are factors that directly influence the capacity of the network to accommodate the generation systems connected to it, such as the point of connection, the type of connection, whether it will be single-phase, two-phase or three-phase, the power of the system, the technology used, the network configuration electricity and also the efficiency of the systems. Thus, this study seeks to understand the impacts of these factors on the UFMG university campus network in order to propose the best alternative that would allow the maximum potential for distributed generation injection, without violating any PQ parameter. With the result, it was possible to understand the impacts due to the injected power of the systems in the network, and also their location, it emphasizes that the analyzed system is characterized by being three-phase and balanced in relation to the connected loads, lines and distributed generation systems. |
