Performance Of A Dynamic Voltage Restorer For A Practical Situation

Among most severe power system disturbances those degrading power quality are voltage sags and transient interruptions. Even voltage sags lasting only a few tens of
milliseconds are enough to bring entire production lines to standstill, causing considerable economic damage as well as endangering the production equipment. Therefore necessary measures have to be taken to protect sensitive loads which are susceptible to these voltage disturbances. Among the solution candidates such as, Uninterruptible Power Supplies, Motor-Generator Sets, etc, Dynamic Voltage Restorer (DVR) which is an effective custom power device has been proposed to mitigate such bus voltage sags on sensitive loads with its excellent dynamic performance.

In this study, load side connected shunt converter topology was chosen for the implementation of DVR. The performance DVR was tried to be improved by improving the control strategy used. Super Film located in Gaziantep which is one of
the SANKO subsidiary company was chosen to simulate the operation of DVR as actual case of Turkish industry. All the simulations in this study were carried on PSCAD/EMTDC Software.
