A Survey on Different types of Flexible AC Transmission Systems (FACTS) Controllers

  Naseeb Khatoon,  Sajida Shaik

In the last two decades, power demand has increased substantially while the expansion of power generation and transmission has been severely limited due to limited resources and environmental restrictions. As a consequence, some transmission lines are heavily loaded and the system stability becomes a power transfer-limiting factor. Flexible AC transmission systems (FACTS) controllers have been mainly used for solving various power system steady state control problems. For the development and improvement of dynamic performance of the modern power system, Flexible AC Transmission Systems (FACTS) devices have been used since 1970s. A Flexible Alternating Current Transmission System (FACTS) is a system composed of static equipment used for the AC transmission of electrical energy. FACTS devices use power electronic components to improve system performance. FACTS controller includes Fixed Capacitor Thyristor Controlled Reactor (FC_TCR), Static Synchronous Compensator (STATCOM), Thyristor Controlled Series Compensator (TCSC), Static Series Synchronous Compensator (SSSC), Static VAR Compensator (SVC), Unified Power Flow Controller (UPFC), Hybrid Flow Controller (HFC), Rotary Hybrid Flow Controller (RHFC), Amalgam Power Flow Controller (APFC) which are used in the transmission and distribution system to improve power transfer capability and to enhance power system stability. In this paper review on different types of FACTS controller has been discussed and also a new device of FACTS family named as amalgam power flow controller (APFC) is introduced and also gives idea regarding various applications of FACTS controllers.
