Resonance characteristics of offshore wind turbine structures founded on partially embedded pile groups

open access: yesYantu gongcheng xuebao, 2019
Resonance occurs when the first natural frequency of wind turbines coincides with frequencies of the rotor rotation and blade passing, which may cause damage to wind turbines in serious conditions.

Effect of blade tips ice on vibration performance of wind turbines

open access: yesEnergy Reports, 2023
There are abundant wind resources in cold regions. Therefore, it is essential to systematically study some icing situation of wind turbines blades (especially the blade tip area) to reduce the loss of wind turbines blades caused by faults, which has ...

Determination of wind turbine far wake using actuator disk [PDF]

open access: yes, 2014
The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of upcoming wind cannot be valid. The

A comparative analysis of carbon reduction potential for directly driven permanent magnet and doubly fed asynchronous wind turbines

open access: yesEnergy Science & Engineering, 2023
Wind power generation does not emit greenhouse gases or pollutants, but there are some carbon emissions from the manufacturing, transportation, operation, and waste disposal of wind turbines.
