ADVANTAGES OF UPFC PDF

A unified power flow controller 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. Unified Power Flow Controller UPFC , as a representative of the third generation of FACTS devices, is by far the most comprehensive FACTS device, [2] 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. 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.

Published on Dec 22, The significance of power factor correction PFC has long been visualized as a technology requirement for improving the efficiency of a power system network by compensating for the fundamental reactive power generated or consumed by simple inductive or capacitive loads.

The drivers that have resulted in this proliferation are a direct result of the availability of low-cost switch-mode devices and control circuitry in all major end-use segments: residential, commercial, and industrial.

The UPFC consists of a combination of a series device and a shunt device, the dc terminals of which are connected to a common dc link capacitor.

The overall result over the power system is that it improved the power factor. So it bring the present power system at better economy level Thank you. You just clipped your first slide!
