A Novel Dynamic Voltage Restorer with Outage Handling Capability Using Fuzzy Logic Controller
0 likes27 views
The document discusses a novel dynamic voltage restorer (DVR) utilizing a fuzzy logic controller to address significant voltage sags and outages in low voltage distribution systems. The DVR can operate as an uninterruptible power supply (UPS) when sags exceed 10% of nominal voltage, with laboratory test results demonstrating its effectiveness. The system compensates for disturbances such as phase jumps and unbalanced conditions, ensuring stable load voltage during outages.

CONCLUSION:
A dynamic voltage restorer using Fuzzy Logic controller was demonstrated to remedy sags and
outage voltages. Phase jumps and unbalanced conditions due to single phase-to-ground fault can
also be compensated by the DVR. In the event of outage, where the voltage drops below 10%,
the DVR restore the voltage into the normal. Thus, the load voltage is unaffected by the
disturbances including sags and outages.

The DVR recovers sags up to 10% of nominal voltage; otherwise, it will operate as an uninterruptible power supply (UPS). A transformer is connected in series with the load when restoring sags, and is reconfigured into parallel connection using switches when handling outages. The controller uses a Fuzzy Logic with 3 inputs to maintain the load voltage through d-q transformation. Preliminary results from laboratory tests are also presented in this paper.
