摘要	This paper proposes a novel detection approach for transient power quality (PQ) disturbance based on fuzzy adaptive mathematical morphology filter and S-transform. At first, a fuzzy adaptive morphological filter is designed to pretreat the disturbance wave to filter random/impulse noise in PQ disturbance signals. Thus the filter can hold the fundamental characteristics of original signals. Then, regarding the filtered signals, the amplitude envelope based on S-transform is applied to detect the start and end time that the disturbance occurs. Finally, voltage signals which contain noise and electromagnetic transient phenomena, such as voltage swell, interruption and voltage sag, are illustrated in simulation. The simulation results show that the proposed detection approach has the feature and advantages of being simple, rapid and accurate.
