The invention relates to a power quality transient event recognition method and system, a computer device and a computer storage medium. The power quality transient event recognition method includes the steps that a voltage cycle signal and a current cycle signal are correspondingly sampled at a set frequency, and a discrete voltage signal corresponding to the voltage cycle signal and a discrete current signal corresponding to the current cycle signal are determined; a voltage identification queue is determined according to a set number of discrete voltage signals generated at a current time,and a current identification sequence is determined according to a set number of discrete current signals generated at a current time; and a power quality transient event is identified according to the voltage identification queue and the current identification sequence. The power quality transient event recognition method and system, the computer device and the computer storage medium enable theidentification process of the power quality transient event to be based on the set number of the discrete voltage signals and the discrete current signals generated at the current time, and have highrecognition precision.
