Dynamic voltage restorer based on fuzzy logic control for voltage sag restoration

International Conference on Sustainable Energy and Intelligent Systems (SEISCON 2011), 2011
Power quality problems such as voltage sags are presently impor tant issues in the industrial field. The dynamic voltage restorer (DVR) is a series compensation device that mitigates voltage sag problems. Due to the nonlinearity of the D VR dynamic character istics, the compensating performance of the D VR is affected much by its control strategy.
