Abstract:
This paper use the methods of S transformation to test the starting time, the end of the time, frequency and
amplitude characteristics of common transient power quality signal disturbance. Through error analysis and simulation
show that this method can accurately determine the disturbance occurred time and duration, and the identification and
determination of disturbance can be simple and intuitive. It has the practical value and realistic significance to power
quality signal interference analysis.
