Abstract
Modern power systems are continuously being expanded and upgraded to cater the need of ever growing power demand. This paper explains the problems that are due to poor Power Quality in electrical systems and shows their possible financial consequences and improvement of power quality. Power Quality is characterized by parameters that express harmonic pollution, reactive power and load unbalance.. It is shown that by using the right technology a variety of Power Quality problems can be solved rendering inst allations trouble free and more efficient, and can render them compliant with even the strictest requirements. Flexible AC transmission systems or FACTS are devices which allow the flexible and dynamic control of power systems. . Finally, an introduction to the basic circuits of several FACTS controllers is provided with a focus on their system performance characteristics.
