Re: UPFC in Transmission Line

A Unified Power Flow Controller (UPFC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks.

The UPFC concept was described in 1995 by L. Gyugyi of Westinghouse.

It uses a pair of three-phase controllable bridges to produce current.

The controller can control active and reactive power flows in a transmission line.

The UPFC is a combination of a static synchronous compensator (STATCOM) and a static synchronous series compensator (SSSC) coupled via a common DC voltage link.

The UPFC uses solid state devices, which provide functional flexibility, generally not attainable by conventional thyristor controlled systems.

The main advantage of the UPFC is to control the active and reactive power flows in the transmission line. If there are any disturbances or faults in the source side, the UPFC will not work.

The UPFC operates only under balanced sine wave source.

The controllable parameters of the UPFC are reactance in the line, phase angle and voltage.
