Numerical Investigation of Terrain-Induced Turbulence in Complex Terrain Using High-Resolution Elevation Data and Surface Roughness Data Constructed with a Drone

Numerical Investigation of Terrain-Induced Turbulence in Complex Terrain Using High-Resolution Elevation Data and Surface Roughness Data Constructed with a Drone
Using the method based on unmanned aerial vehicle (UAV) imagery, two kinds of data can be obtained: the digital elevation model (DEM) for the digital expression of terrain, and the digital surface model (DSM) for the digital expression of the surface of the ground, including trees.

A Large-Eddy Simulation-Based Assessment of the Risk of Wind Turbine Failures Due to Terrain -Induced Turbulence over a Wind Farim inComplex Terrain

A Large-Eddy Simulation-Based Assessment of the Risk of Wind Turbine Failures Due to Terrain -Induced Turbulence over a Wind Farim inComplex Terrain
The first part of the present study investigated the relationship among the number of yaw gear and motor failures and turbulence intensity (TI) at all the wind turbines under investigation with the use of in situ data. The investigation revealed that wind turbine #7 (T7), which experienced a large number of failures, was affected by terrain-induced ...
