Abstract: In this paper facts devices used for power quality improvement is presented. In addition, the power electronics-based equipment, which are called power conditioners are used to solve power quality problems. Since the topologies of these equipment are similar to those used in FACTS equipment, power conditioners are also called Distribution FACTS (DFACTS). Shunt connected STATCOM may be used to inject reactive power. A STATCOM will provide general voltage support to the Distribution network and, if this is not desired, a solid state switch can also be used to isolate the load and STATCOM for the duration of the sag. The principle operating modes and applications whichever one of equipment in transmission and distribution system (such as STATCOM, SSSC, UPFC, D-STATCOM, DVR and UPQC) will be discussed.
Keywords: POWER QUALITY, FACTS DEVICES.
