DVR Control Strategy for Dynamic Power Quality Disturbance Mitigation
      Sanjay A Deokar, Laxman M Waghmare
Abstract: The dynamic voltage restorer (DVR) is a series connected device for mitigating voltage sag/This paper presents with feed forward pre-sag/swell voltage control method to regulate the output voltage of pulse width modulated (PWM) voltage source converter (VSC). The proposed controller maintains a constant load voltage under the multiple balanced/unbalanced dynamic PQ disturbances. The proposed DVR control scheme based on park’s transformation is a simpler, lower cost. It is able to compensate multiple sag/swell accurately and can achieve fast response under dynamic load conditions. The detail simulation of 440 volts, 50 Hz distribution system has been carried out to evaluate the performance of DVR for the mitigation of multiple voltage sag/swell with the help of Mathworks Matlab/Simulink for both balanced and unbalanced load conditions. The simulation results are presented for various combinations of dynamic PQ problems.
