Data-Driven Method for Wind Turbine Yaw Angle Sensor Zero-Point Shifting Fault Detection

Energies, 2018
Wind turbine yaw control plays an important role in increasing the wind turbine production and also in protecting the wind turbine. Accurate measurement of yaw angle is the basis of an effective wind turbine yaw controller.

Experimental study on impact resistance ofultra-high-strength spherical structures

Baozha yu Chongji
To explore the anti-penetration abilities of irregular structures made of high-strength alloy steel, a target enhanced with ultra-high-strength spherical structures (UHS-SS) was manufactured in this work. The UHS-SS is fabricated from ultra-high-strength

Automobile plane-motion model including roll motion: Second report (Taking into consideration phase difference of cornering forces between front and rear wheels)

Nihon Kikai Gakkai ronbunshu, 2016
The roll motion of the vehicle has an effect on the yaw natural frequency. Because the yaw natural frequency formula considering this effect is the solution to a quartic equation, the expression of the formula is thought to be complex and ...

A Review of Diagnostic Methods for Yaw Errors in Horizontal Axis Wind Turbines

Energies
Yaw errors occur in wind turbines either during the installation stage or because of the aging of devices. It reduces the wind speed in the rotor axial direction and increases the structural loads in the lateral direction.
