摘要：

A modified generalized S transform is designed to extract the parameters of power quality disturbances such as starting and ending time, amplitude, harmonic frequencies more accurately in this paper. The demands of power quality detection is better met by controlling the Gaussian window function. Finally, the simulation results show that the excellent time-frequency performance of this method.
