Damping of Power System Oscillations using Unified Power Flow Controller (UPFC)
-This paper presents a systematic approach for designing Unified Power Flow Controller (UPFC) based damping controllers for damping low frequency oscillations in a power system. Detailed investigations have been carried out considering four alternative UPFC based damping controllers. The investigations reveal that the damping controllers based on UPFC control parameters δE and δB provide robust...
متن کاملDamping of power system oscillations with unified power flow controller (UPFC)
A comprehensive approach to the design of UPFC controllers (power-flow controller, DC-voltage regulator and damping controller) is presented. Studies reveal that damping is adversely affected by the incorporation of a DC-voltage regulator. Investigations were carried out to understand the relative effectiveness of modulation of thc UPFC control signals inR, SB, niE and <5£ on damping of the sys...
متن کاملGlobal Power System Control Using a Unified Power Flow Controller
This paper explores the use of a Unified Power Flow Controller (UPFC) for global power system control. Coordinated control schemes are assigned to the UPFC, Power System Stabilizer (PSS) and generator excitation to maintain transient stability and voltage stability following a disturbance. The extension to use of UPFC in damping inter-area oscillation is also considered. Under the proposed coor...
