英文摘要	It can be a premise and basis for the analysis and evaluation of the voltage sag disturbance level to detect the start-stop time and the duration of sag accurately and quickly. A self-adaptive threshold method was proposed based on information-entropy. Using this method, the starting and ending time of the voltage sag were detected and located, and then the voltage sag duration can be calculated. The simulation with different dropping amplitudes and harmonic waves and noise shows that this method not only has simple principle, but also has higher detection accuracy and strong adaptability.
