Identification of collision sensitive niches could be a powerful tool for landscape planning; helping avoid regions with higher risks of collisions for turbine allocations and thus protecting sensitive bird populations.Similar content being viewed by others Responses of birds and mammals to long-...
• Construction The wind turbine parts are manufactured and pre-assembled into the main components at the factory then shipped to the wind farm site where the final assembly will take place. When all components have been received, the assembly can take place. A crane is used to erect the ...
This type of turbine is unusual and its application for obtaining useful energy from air stream is an alternative to the use of conventional wind turbines. Simple construction, high start up and full operation moment, wind acceptance from any direction, low noise and angular velocity in operation...

22、orced concrete road construction needed to move the turbine and the sections of the tower to the building site transformer needed to convert the low voltage (690 v) current from the turbine to 10-30 kv current for the local electrical gridinstallation cost factors - continued telephone conn...
Due to its low cost, brushless rotor construction does not need a separate source for excitation. No maintenance and self-protection against severe over loads, short circuits, and self-excited induction generators are used in wind-turbine applications [142–146]. The only drawback of these types...
Vibration analysis is an effective tool for the condition monitoring and fault diagnosis of wind turbine drivetrains. It enables the defect location of mechanical subassemblies and health indicator construction for remaining useful life prediction, which is beneficial to reducing the operation and maintenan...
One of the maintenance requirements introduced is the replacement of the gearbox every 5 years during the 20-year lifetime of the wind turbine. This is a costly task, as the replacement of a gearbox accounts for about 10% of the construction and installation cost of the wind turbine, and ...
A patented floater motion controller, which ensures the floating wind turbine remains stable while delivering optimal power production, introducing new features and adapted to semi-concepts. A new floater substructure complementing the Hywind spar, based on simple geometry design and passive ballast, that...
