FACTS:Flexible Alternating Current Transmission System For Cost Effective and Reliable Transmission of Electrical Energy
ABSTRACT:
Flexible alternating current transmission systems (FACTS) devices are used for the dynamic control of voltage, impedance and phase angle of high voltage AC lines. FACTS devices provide strategic benefits for improved transmission system management through better utilization of existing transmission assets; increased transmission system reliability and availability; increased dynamic and transient grid stability; increased quality of supply for sensitive industries (e.g. computer chip manufacture); and enabling environmental benefits. Typically the construction period for a facts device is 12 to 18 months from contract signing through commissioning? This paper starts by providing definitions of the most common application of FACTS devices as well as enumerates their benefits (focusing on steady state and dynamic applications). Generic information on the costs and benefits of FACTS devices is then provided as well as the steps for identification of FACTS projects. The paper then discusses seven applications of FACTS devices in Australia, South Africa and the USA. The paper concludes with some recommendations that could facilitate the increased usage of FACTS.
