Estudo dos efeitos dos harmônicos gerados por residências na rede de distribuição secundária

Abstract

Currently the energy provider seeks improvements in energy quality supplyed in the eletrical system due to the reactive energy levels existente in the system that can cause huge losses of energy and provide potential. Whit the electronic tecnological advance have providing a greater comfort to the users of the system with regard energy consumption, in addition to the emergence of more efficient equipment energy. Although, this equipments have the caracteristic of not presenting linear relation whit tension and current (none linear charges), generating harmonics which are injected into the low voltage network. Presents a theoretical framework on harmonics and its main effects in the distribution system, also getting the types of filters used to correct them. Then, in order to verify the efficacy of a tuned passive filter RLC type next to the transformer of the distribution network to mitigate the levels of current harmonics, the project and the simulation of a filter were made and the final results were examined.
