MODELLING AND SIMULATION OF DYNAMIC VOLTAGE RESTORER FOR POWER QUALITY
Minaxi L. Patel, Prof. Sanjay R. Vyas
Abstract :
This Paper presents modeling, analysis and simulation of a Dynamic Voltage Restorer (DVR) using MATLAB. A PI controller and Discrete PWM pulse generator was used in this model. The main aim of the DVR is to regulate the voltage at the load terminal irrespective of sag/swell, distortion, or unbalance in the supply voltage. The DVR is a power electronic based device that provides three-phase controllable voltage source, whose voltage vector (magnitude and angle) adds to the source voltage during sag event, to restore the load voltage to pre-sag conditions. An adequate modeling and simulation of DVR, including controls in MATLAB, show the flexibility and easiness of the MATLAB environment in studying and understanding such compensating devices.
