Abstract

The most power quality disturbances such as voltage sag and swell that occur in the distribution side can be compensated by using custom power device dynamic voltage restorer (DVR). This paper describes the techniques for compensation of voltage sag and voltage swell by DVR based on Voltage Source Converter (VSC). Voltage source inverters are capable of generating accurate high quality voltage waveforms and form the power electronic heart of the custom power device. The model has to be simulated with MATLAB/Simulink program to demonstrate system behavior of dynamic voltage restorer with hysteresis controller. The operation of the DVR can be explained with non-linear loads. The DVR are also to be demonstrated on the practical distribution bus system.
