Unified Power Flow Controller (UPFC) is recognized as the most powerful flexible AC transmission systems (FACTS) device for power system. This paper presents a review of the most powerful FACTS device UPFC (Unified The potential benefits of FACTS equipment are now widely recognized by the. BENEFITS OF FACTSRegulation of power flows in prescribedtransmission routes .Reduces the need for construction of newtransmission lines.

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

By using this site, you agree to the Terms of Use and Privacy Policy. It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer.

The UPFC operates only under balanced sine wave source. The controllable parameters of the UPFC are reactance in the line, phase advantagse and voltage.

Unified power flow controller – Wikipedia

The UPFC uses solid state devices, which provide functional flexibility, generally not attainable by conventional thyristor controlled systems. Please help improve this article by introducing citations to additional sources.

Archived from the original PDF on Unified Power Flow Controller UPFCas a representative of the third generation of FACTS devices, is by far the most comprehensive FACTS device, in power system steady-state it can implement power flow regulation, reasonably controlling line active power and reactive power, improving the transmission capacity of power system, and in power system transient state it can realize fast-acting reactive power compensation, dynamically supporting the voltage at the access point and improving system voltage stability, moreover, it can improve the damping of the system and power angle stability.

If there are any disturbances or faults in the source side, the UPFC will not work. From Wikipedia, the free encyclopedia.
