摘要：

Voltage sags in distribution system occur more frequently and devastatingly than other power quality problem. Voltage sags due to line faults, transformer energizing and induction motor starting are main interference sources. The reasons leading to these sags are analyzed and simulation result Are presented by an EMTP modal in this paper. A new identification method to sag waveforms is presented in this paper, since B-spline wavelet transform is good at the analysis of singularity. The characteristics of sag waveform are extracted easily and accurately by using B-spline wavelet transform.
