UPFC based Power System

Abstract

Abstract

Unified Power Flow Controller (UPFC) is one of the most versatile FACTS controller for the regulation of voltage and power flow in a transmission line, which can control power system parameters such as terminal voltage, line impedance and phase angle. Therefore it can be used not only for power flow control, but also for power system stabilizing control. Unified Power Flow Controllers are able to direct reactive and real power flows through a designated route and regulating the system voltage through reactive power compensation. Thus, UPFC provides several features for power flow control namely: voltage control through shunt compensation, real power flow control through quadrature voltage injection and reactive power flow control through in-phase voltage injection. Hence, the ability of facilities of transmission can be better utilized. The process of these three control methods of UPFC for enhancing the transient stability of the power system must be examined.
