Estudo e simulações sobre qualidade de energia elétrica.

Abstract

The possibility of the use of electricity in applications that bring comfort and convenience to its users, representing a significant increase in the quality of life of populations. Initially, what mattered most in this process was the amount of people benefited, however, as this benefit was incorporated into the daily lives of people, other things began to gain prominence as quality. In an early analysis, we are concerned always with continuity of service, since any disruption in supply causes various disorders. However, when the power treated as a commercial product, besides harm others perceive the interruptions, for example, a malfunction of some equipment. This fact is credited to electronic loads, because they distort the waveform of voltage and current are handed to him. And as a result, generate an "pollution" in the network of electricity supply, which affects the proper functioning of these charges. "Pollution" mentioned comes in different types of problems or disorders, which will be fully explained in this paper. Several factors allow us to make an assessment of the quality of electric power, among them we can mention the continuity of their supply; fluctuations, harmonic distortions and imbalances voltage, and the interference with communications systems. On this track, the goal of this work is completion of course describe these and other aspects of the Power Quality in the light of current legislation.
