Design and control of a dual-function device with simultaneous DVR and FCL capability

Dynamic voltage restorer (DVR) is a protecting device for sensitive loads which compensates grid fluctuations. Although using fault current limiting devices (FCL) method of and electrical networks against short circuits. In recent years, some methods have been proposed to combine these two reduce the cost converters use benefits each simultaneously. A new topology control DVR an FCL presented in this paper, with just adding switch conventional DVR, performance will be available network. The FCL-DVR has developed provide excellent dynamic faster response time network failures while maintaining appropriate reliability low converter cost. ability investigated by simulation results.
