Quantitative Relationship of Wind Vibration Coefficient, Average Wind Speed and Damping Coefficient of United Framework of Transformer Substation

Abstract

The united frameworks of UHV and EHV substation belong to wind-sensitive structures, and wind load is one of the main control loads of the design. In this paper, a 500kV full united substation framework was used as the engineering background to explore the quantitative relationship between wind-induced vibration coefficient, damping coefficient and average wind speed of the full united framework. The results showed that the average wind speed and the damping coefficient of the framework have significant influence on the wind vibration coefficient of the framework. The research results in this paper not only provide theoretical and computational basis for the wind resistant design of the combined framework structures, but also provide a basis for formulating the design criteria of full united wind vibration coefficient.
