WIND FORM STABLISATION USING UPQC SYSTEM

Abstract

The extensive use of non-linear loads in domestic, industrialand commercial
services origin harmonic complications.Harmonics make malfunctions in
profound equipment, voltage drop across the network, conductor heat
increases and overvoltage through resonance. All these problems can be
remunerated by using Unified Power Quality Controller (UPQC) and the
operation of UPQC depends upon the available voltage across capacitor
present in dc link. If the capacitor voltage is maintained constant then it gives
satisfactory performance. The proposed research is basically on designing of
Wind energy fed to the dc link capacitor of UPQCso as to maintain
propervoltageacross it and operate the UPQC for power quality analysis. The
proposed technique is the grouping of shunt and series Active Power Filter
(APF) to form UPQC which is fed wind energy system and connected to grid
for better response in the output. In this paper, the simulation model of series
APF, shunt APF, UPQC and Wind energy with UPQC are design in Matlab.
The proposed Wind energy-UPQC is design in Matlab simulation for
reduction of voltage sag, swell, harmonics in load current and compensation
of active and reactive power.
