Comparison of wind-induced responses of transmission tower in normal wind field and downburst wind field

نویسندگان

چکیده

Abstract To study the difference in wind-induced response of transmission tower caused by downburst and well-conditioned wind field, this paper uses harmonic superposition method to simulate field field. The responses under two farms are obtained compared through analysis. fields on quite different, can cause a larger response.

Modelling studies of wind field

Increasing load of air pollution in urban environment emphasises the need for detailed evaluation of wind characteristics that significantly affect the air quality of urban areas, especially, in large agglomerations. This paper includes analysis of urban wind cli-matology and estimation of wind profiles based on measurements of the new urban 5 climate station located at the E ¨ otvös University...

Arma Representation of Wind Field

The dynamic response analysis of structures subjected to a stochastic wind field is carried out in the time domain by a step-by-step integration approach. The loading is represented by simulated time histories of the aerodynamic force. The auto-regressive and moving average (ARMA) recursive models are utilized to simulate time series of wind loads. Depending on the system dynamic characteristic...

Wind Turbine Tower Resonance

Wind turbine towers are large structures designed to withstand the unique loading conditions imposed on them by the turbine’s nacelle and dynamic forces from the rotating blades. Observations and noise measurements of a particular wind turbine showed high noise levels at approximately 48 Hz, which could not be explained from the usual known potential noise sources. Correlated far field noise me...

Wind Field Models and Model Order Selection for Wind Estimation

A bstract-Traditional scatterometer wind estimation inverts the model function relationship between the wind and backscatter a t each resolution element, yielding a set of ambiguities due to the many-to-one mapping of the model function. Field-wise wind estimation dramatically reduces the number of ambiguities by estimating the wind for many resolution elements, simultaneously, using a wind fie...

Wind field retrieval from SAR compared with scatterometer wind field during ERS Tandem phase

Several recent works [such as Vachon et al. 1996, Scoon et al. 1996 and Korsbakken et al. 1997] report promising results when wind retrieval models developed for the wind scatterometer (WSC) are applied to SAR data. The general conclusion from these works is that more validation is needed since the available in-situ material is relatively limited. A dataset from the ERS-1/2 Tandem phase allows ...
