Unified power flow controller
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, advantwges 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.
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 uses solid state devices, which provide functional flexibility, generally not attainable by conventional thyristor controlled systems.
