Minimization of Voltage Sag/Swell by Simultaneous Controlling Of Active and Reactive Powers in UPQC-S
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
This paper aims at presenting the new concept of controlling active and reactive powers simultaneously (complex power) with the help of the series inverter of UPQC, introduced and termed as UPQC-S. The new proposed concept of the UPQCS approach is mathematically formulated and analyzed for voltage sag and swell conditions in power systems. The developed comprehensive equations for UPQC-S can be effectively utilized to estimate the required series injection voltage and the shunt compensating current profiles (both magnitude of simultaneous voltage sag/swell and load reactive power sharing feature of series part and phase angle), and the overall VA loading both under voltage sag and swell conditions. . The simulation studies illustrate the effectiveness of the proposed concept of UPQC-S.
