Re: UPFC Introduction

I will tell you little introduction about Unified Power Flow Controller so that you can go through the information easily.

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

It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer.

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

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

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.
