It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer. Archived from the original PDF on You can help Wikipedia by expanding it. The UPFC uses solid state devices, which provide functional flexibility, generally not attainable by conventional thyristor controlled systems. Retrieved from ” https: A unified power flow controller electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks.
Unified power flow controller
From Wikipedia, the free encyclopedia. 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 advantagex point and improving system voltage stability, moreover, it can improve the damping of the system and power angle stability.
The controller can control active and reactive power flows in a transmission line. A new approach to power transmission control” PDF.
