Abstract

Reasonable construction of numerical simulation method of strong wind field is of great importance for exploring accurately the wind-induced response law and wind-resistant stability of such typical power facilities as transmission towers and wind turbine towers under action of strong wind.It is also a hot issue in the field of power transmission and distribution engineering.In view of the insufficient consideration of the characteristics of strong wind field in existing study and relevant specifications

a kind of numerical simulation method of strong wind field in large field and inflow space is proposed in this paper.Firstly

the numerical simulation process of strong wind field and the simulation method of average wind speed are introduced.Secondly

kurtosis and skewness are introduced to perform mathematical description of non-Gaussianity characteristic of fluctuating wind speed with consideration of nonGaussianity probability statistical feature and spatial distribution correlation of strong wind fluctuating wind speed of large field and inflow space.The mathematical model of strong wind fluctuating wind speed is constructed based on linear filtering AR model and Gurley correlation transformation and the numerical simulation of the strong wind field is achieved.Finally

the transmission tower in actual project is selected as the calculation case to simulate and verify the space strong wind field.The results show that the simulation method of strong wind field in this paper is more suitable for actual working conditions

and can be applied to different working conditions through parameter modification.It can also provide reliable study base for the wind-induced response analysis

failure probability calculation and wind-resistant design of such space structures as transmission tower and wind turbine towers etc.
