Transient Stability Improvement using FACTS Devices

Pradeepkumar S. Mahapure | A. R. Soman

Abstract: FACTS devices used in electrical systems form one of the important aspects of power electronics revolution that are taking place in electrical areas. Use of several Technological FACTS devices in Electrical power system is because of advanced researches in power electronics. This revolution in power electronics is happening and different applications in electronic system will tend to expand and increase day by day. Almost unique and ideal quality and properties of FACTS controllers that is possible to implement so to improve transient and overall stability of Electrical network, as when using these controllers it allows to have control on network conditions by giving quick response in less time by control on reactive energy which will further result in enhancement of electric energy. Stability in System and operation in electrical power systems during huge disturbances and faults can be obtained by maintaining Transient stability as Transient stability control plays important role in control of power system parameters. By employing UPFC in network it plays an important role as it acts as effective FACTS (Flexible AC Transmission System) equipment. It is possible to obtain control on the true or real, reactive energy flowing along network through changing accordingly series and shunt values, and when FACTS devices are attached with On Site Generation (ONG) or Decentralised energy by connecting it using DC link to obtain control on disturbances created during or by faults results in improvement of overall stability of a electrical network. To show different capabilities of UPFC study of collection of overall performance characteristics is presented. Different FACTS controllers can be used are Static Synchronous Series Compensator (SSSC), Thyristor Controlled Series Capacitor (TCSC), and Static VAR Compensator (SVC) respectively are compared with UPFC and performance of UPFC against other FACTS controller is checked.
