Development of a Monitoring System for the State of the Main Components of the Wind Turbine [PDF]
To date, there is a problem in the high cost of maintenance costs for wind turbines, this is due to the remote location of wind turbines from civilization, as well as the high location of the turbines above the ground [1].

Blockage effects in wind farms
An experimental study of wind farm blockage has been performed to quantify the velocity decrease that the first row of a wind farm experiences due to the presence of the other turbines downstream.

Clarification of influences of inflow conditions on wake of horizontal axis wind turbine
In recent years, wind turbines are introduced in wind farms in which some wind turbines are concentrated. When wind turbines are built in contiguity with each other in wind farms, the flow passing through a wind turbine, which is called wake, may flow ...

Dynamics and stability of wind turbine generators [PDF]
Synchronous and induction generators are considered. A comparison is made between wind turbines, steam, and hydro units. The unusual phenomena associated with wind turbines are emphasized.

Wind turbine condition assessment through power curve copula modeling [PDF]
Power curves constructed from wind speed and active power output measurements provide an established method of analyzing wind turbine performance. In this paper it is proposed that operational data from wind turbines are used to estimate bivariate ...

Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Converter Analysis for Small Wind Turbine Applications [PDF]
Current environmental concerns and expensive infrastructure costs have a significant impact on the adoption of wind turbine technology. Research on the technologies of small wind turbines, which are much smaller in size and capacity, has increased ...

Effect of blade tips ice on vibration performance of wind turbines
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 ...
