The authors discuss a new numerical simulation method of the downburst wind loads on the basis of the previous research. Firstly, the wind speed is expressed as the sum of an instantaneous mean wind speed and an amplitude-modulating non-stationary fluctuating wind speed. Secondly, a new method based on the modified Osegguera and Bowles/Vicroy model to simulate the mean wind is presented and the fluctuating wind is simulated by a modified spectral representation method.

AR model in linear filter theory is adopted to simulate pulsant wind. Combined with some typical cable-membrane structures, research on self-vibration of the structure has been conducted. Based on the previous work, the influence caused by the vertical wind component on the membrane roofs has been analyzed in time domain. It includes the vibration laws of the structure under separate horizontal wind component, separate vertical wind component and the collective horizontal wind component and vertical wind component. Significant conclusions have been drawn from the analysis.

The complete wind turbine speed control firstly proposed here also improves the tracking effect of wind turbine rotating speed to variable wind speed. Wind turbine rotating speed synchronized power observer compensates the power ripple of wind turbine resulted in inverter dead time. A low pass filter used at the output of MPPT controller smoothes the speed reference, which makes the rotating speed of wind turbine more stable.
