THE DYNAMIC RESPONSE OF WIND TURBINE GENERATORS FLEXIBLE STRUCTURES TO THE TURBULENT WIND EFFECT
Abstract
The high risk of construction-assembly activities, the high costs of leased equipment, the pressure to finish installing/uninstalling as quickly as possible, create an environment conducive to ignoring safety practices, especially if the rules do not become mandatory, even if they are known.
The purpose of this article is to analyze the response of a wind turbine metallic tubular tower to wind action when, for various reasons, during operation, dismantling or installation, circumstances can arise that leave the structure to remain in a preserved state in different stages.
The dynamic response factor of the structure was evaluated using the Romanian National Design Code and Eurocode 1. The relationships are based on the hypothesis that only the vibrations of the structure in the direction of the wind, corresponding to the fundamental mode of vibration, are significant.
Because the structure presented is isolated, high and slender, the article also examines the probability of occurrence of interaction effects between vortex shedding and galloping.
