A eficiência energética também engloba o tema da qualidade de energia, que será tratada neste trabalho no âmbito do estudo da ressonância entre uma instalação elétrica e as capacidades de uma bateria de condensadores compensadora do fator de potência.
O trabalho utiliza dados recolhidos nas instalações do Instituto Politécnico de Bragança. A metodologia adotada no trabalho foi o equacionamento da indutância da rede e a correlação da mesma com a capacidade da bateria. Os dados foram obtidos por analisadores de energia.
Após o desenvolvimento da metodologia com a premissa de uma rede indutiva, que é uma suposição comum, foi constatado pelas medições que a rede teve seu comportamento deslocado para uma característica capacitiva. A datação deste comportamento foi aferida e mostrada no trabalho.
O trabalho foi concluído com a premissa de que pode ser aplicado para redes com características indutivas, podendo ser estendido para aplicações industriais.
Energy efficiency also encompasses the energy quality theme, which will be addressed in this work in the context of the study of resonance between harmonics and the capacity of a battery of condensers that compensate the power factor. The work took place in the facilities of the Polytechnic Institute of Bragança. The methodology adopted in the work was the equation of the inductance of the electric network and the correlation of it with the capacity of the battery. The database was obtained by energy analyzers before being equated. After the development of the equation with the premise of an inductive network, which is a common assumption, it was verified by the measurements that the network had its behavior shifted to a capacitive characteristic. The dating of this behavior was measured and shown at work. The work was completed with the premise that it can be applied to networks with inductive characteristics and can be extended to industrial applications.
