Taking the Xiangjiaba-Shanghai special high-voltage DC??800kV transmission line project being constructed as an example, based on the basic characteristics of fluctuating wind and Kaimal spectra, considering various influences such as structural style of long span transmission tower,characteristics of power spectral energy i.e,the improved weighted amplitude wave superposition (WAWS) method adopting the decimation-in-time fast Fourier transform (DIT-FFT) technology in time domain was proposed, the time-history of fluctuating wind speed of long span transmission tower was simulated,which aimed to gain an insight into the characteristics of wind-induced response of long span transmission tower under wind loads via the time-history analysis.and to display intuitively the effectiveness of wind vibration control of long span transmission tower in the time domain.The correctness and the effectiveness of this method are examined by calculating an example,and the wind-induced characteristics, change law and the characteristics of spatial correlation of the time-history of fluctuating wind speed along altitude direction are studied.
