Abstract

In this respect, a high precision simulation method based generalized S-transform （GST） is proposed in this paper for multivariate non-stationary winds. Firstly, the window function parameters are investigated to obtain a clearer time-frequency resolution. Further, the particle swarm optimization （PSO） method is used to optimize the parameters of GST window function. The optimized GST time-frequency spectrum is used for simulation, the high precision multivariate non-stationary wind speed samples are then generated. Finally, the effectiveness and superiority of the proposed method are verified by numerical experiments.

Key words
