Abstract |
The paper deals with application of super-twisting sliding mode control in Dynamic Voltage Restorer (DVR) to tackle
various Power Quality (PQ) issues. The various features of super-twisting sliding mode, which include selection of
sliding surface, stability of system, existence of sliding mode and reaching conditions to bring system states on sliding
surface, are discussed for mitigation of voltage sag/swell and phase jumps applications. Pulse width modulation (PWM)
based second order super-twisting sliding mode control is used to operate voltage source converter (VSC) in voltage
control mode for mitigation of voltage sag, voltage swell and phase jumps to regulate power flow to load. The proposed
controller design is simulated for single phase DVR. It exhibits robustness to system parameters and load variations.
The load voltage Total Harmonic Distortion (THD) is calculated to evaluate the voltage quality. MATLAB®/Simulink®
SimPowerSystem tool box is used to check the performance of pr
