Condicionamento e qualidade da energia elétrica

Abstract

Considering the global growing demand for power, durability of non-renewable energy reserves and their impact on the environment, become essential to use technologies that ensure the quality and efficiency in transmission and consumption of energy currently available. In this scenario, the use of FACTS devices - Flexible Alternating Current Transmission Systems allows to dynamically control the line impedance, voltage, active and reactive power flow, and when the energy storage becomes economically viable, its also possible to provide and to absorb active power. Thus, we have greater control of the system and consequent increase in power transfer capability of the system. In this work, initially, are the main electromagnetic disturbances that impact the power of quality, highlighting its causes and effects, then we present the FACTS devices and their applications. Finally, it was found that such devices add, in many ways, the power of quality, but still have certain technical limitations that prevent them from being applied at all levels and situations inherent in the system.
