Principle of wind turbine tower vibration generator

Do wind turbines have a vibration control system?

Over the years, various control systems have been developed to attenuate and mitigate vibration on wind turbines. This paper provides a critical and up-to-date review of wind turbine vibration issues and control strategies, offering an integrated analysis of developments from 2015 to the present.

Does a wind turbine tower have a vortex induced vibration?

Vortex-induced vibration (VIV) of wind turbine tower is a common occurrence in practical engineering, significantly impacting the safety and reliability of structure. An effective method is developed to investigate the VIV characteristics of a wind turbine tower with an elastic foundation and a lumped mass.

How can wind turbines overcome vibration problems?

In recent years, research and development have shown significant interest in overcoming the vibration problem in wind turbine technology by utilising new materials and designs. Installation of those controls has been designed to act separately or combined with WT components, including blade, nacelle, tower, and support.

How can a wind turbine control out-of-plane vibrations?

To address out-of-plane vibrations in both the tower and blades, multiple tuned mass dampers were applied (Zuo et al., 2019), and a TLCD was designed and installed on the tower’s nacelle to control wind-turbine vibrations resulting from concurrent wind and wave loading (Chen et al., 2015a).

Can mechanical vibration affect structural control of wind turbines?

The challenging issues related to structural control of wind turbines due to mechanical vibration are summarized. Recent modeling as well as numerical techniques to simulate wind turbines’ behavior under multihazard dynamic loadings are presented.

Can Vibration Isolation Control the structural response of a wind turbine?

They concluded that the vibration isolation can effectively control the structural responses of the tower under seismic and wind loadings. The wind turbine can experience multi-directions and multi-hazards in an extreme event. Moment and shear load of a wind turbine can be calculated through equations developed through quasi-static analysis.
