Análise de unidades UPFC sob o enfoque da qualidade da energia elétrica

Abstract

Electric power systems have experienced problems with the loading of transmission lines, due to the growing demand of consumption. In this regard, FACTS has emerged as a potential alternative. Associated with these factors, newly designed equipment called “UNIFIED POWER FLOW CONTROLLER-UPFC” has been touted as one of the most promising devices for use in FACTS. In view of the above, and taking into consideration the aspects related to the UPFC's working principle, this master's thesis arises, which, among other purposes, presents and discusses results of computational investigations conducted with a view to the operation of this equipment under the focus on “QUALITY OF ELECTRICITY”.
