A New Technique Implemented in Synchronous Reference Frame for DVR Control under Severe Sag and Swell Conditions

Project Code :TEPGPS564


The main objective of this project is controlling of DVR in distribution systems under severe transient conditions.


This paper proposes a new version of DQ control technique to control dynamic voltage restorer under severe transient voltage conditions. The power system network with the new DQ control technique is studied and analyzed under different scenarios to compensate for severe balanced and unbalanced voltage sags and swells. This new scheme is based on extraction of positive sequence components to implement the control algorithm. A mathematical model of the dynamic voltage restorer (DVR), hysteresis voltage control, converter controller model, new DQ scheme with complete system equations are carried out and verified using Simulink / MATLAB.

Keywords: Balance and unbalanced load, dynamic voltage restorer (DVR), instantaneous space vector, synchronous stationary frame (DQ) theory, voltage sag, voltage swell.
