چکیده مقاله:

Rapid voltage variations in general and voltage flicker in particular caused by arc furnaces or welding plant can be harmful for sensitive loads. In this paper a dynamic voltagerestorer (DVR) is used for compensating the voltage flicker and severe disturbances. This topology is based on a 3-three phaseto a single phase matrix converter (MC) where the ac to ac conversion is provided without any dc energy storage units. Therefore, unlike the conventional DVR the faster response and the reduced size of DVR are prepared. This structure also can be used to restore the voltage sags and swells to protectsensitive loads. To control the DVR, various compensation algorithms have been applied on this matrix based compensator. Its performance under different conditions is examined through simulation studies using PSCAD/EMTDC
