Dynamic voltage restorer(DVR)is one of important power quality control equipment. It can compensate voltage sag accurately and quickly, which demands that voltage sags in grid should be accurately and real-time detected and reference voltage wave should be generated. in this paper a sliding window iterative DFT algorithm based on adaptive sampling algorithm is present. magnitude and phase of the Fundamental component of a sample sequence of can be extracted through sliding window iterative DFT algorithm. under the non-synchronized sampling conditons, adaptive sampling algorithm is be used which can adjust automatically the sampling time. So the algorithm can reduce errors caused by the non-synchronous sampling. The simulation results show that the algorithm can effectively detect the reference instruction voltage and has good real-time, tracing and anti-interference performances.
