Qualidade da energia elétrica gerada através de biodigestores

Abstract

The Power quality is directly linked to the change of power generated pattern, ie the amendment of the frequency sinusoid (60 Hz in Brazil), who for various reasons changes. This change may occur in amplitude and frequency, either through interruption, noise, disturbance, generation and presence of other than the fundamental frequency (60 Hz). All of these disorders can result in malfunction of the equipment and devices, but also influence the supply of electricity. So it requires is an investigation in power quality, so that are avoided all the effects that bring harm to equipment and users. With the increased use of biomass as an energy source, it is necessary to check the quality of this electrical potential generated, because it can bring more losses than gains. If the potential has generated a high load disturbances, various anomalies will be generated in the system or equipment receiving this potential resulting from the potential supply interruption that, through a malfunction and possible breakage of equipment. Thus, this study aimed to evaluate the interference of biochemical targets involved in the conversion of biogas into electricity. Currently there is no standard that addresses basic patterns of energy generated by individual producers that specifies what the basic values of the quantities involved in the generation , then the measurements followed the used power quality parameters were the PRODIST , which deals with distribution electricity and that is a subdivision of ANEEL.The measurements were found differences in values that are determined as rated by ANEEL , and basic and primordial quantities to generate , such as voltage , frequency and power. Factor these that can bring a short-term loss for the individual producer, because the loads connected to the generator and the generator itself may be damaged during the conversion process.
