Potentials and Capabilities of FACTS Controllers for Quality and Performance Enhancement of Power System

At present the demand of electrical power is growing day by day with a very fast rate, so we require much capable transmission and distribution system with the most excellent quality of supply. That’s why power quality is a major issue in the distribution system and this is the area which attracts all electrical engineers. The major impact of poor quality of supply is on the highly loaded distribution system, on which the maximum load is connected. In this paper authors focus on the FACTS technology, classification schemes, applications, potentials and control attributes in terms of the performance and quality issues of power supply. Power quality means the nonstandard supply voltage, supply current and supply frequency, that results malfunctioning or failure of operation of various equipments and accessories. Key Words-FACTS devices, Transmission and distribution system, power quality and Power flow control.
