Advantages of the technical evolution of protection, control and supervision system applied to fixed series compensation

The use of flexible alternating current transmission systems (FACTS) is well known because it provides a lot of benefits to improve the power transfer capacity in transmission lines, as well as power system stability. The simplest and most cost-effective type of FACTS is provided by fixed series compensation (FSC). This paper will present the technical innovations, the advantages and the progess obtained in Brazilian engineering through development of the protection, control and supervision system (PCSS) applied to the FSCs installed on the Mato Grosso State Transmission System (ELETRONORTE Power Transmission Utility - Brazil) at Barra do Peixe 230 kV substation. The paper will describe how the development of PCSS engineering and FACTS project management are making possible to generate high quality and efficient power transmission solutions to the Brazilian Power Transmission System.
