Intelligent yaw control

Precise adaptive wind tracking of the nacelle

For yaw control, Siemens offers highly efficient solutions based on the turbine controller (SIMATIC Microbox PC with WinAC RTX F and ET200-Periphery). They allow for adaptive wind tracking of the nacelle to ensure that it is optimally positioned in the wind at all times. For this purpose, the sensors signal the wind direction to the controller which sets positioning drives in motion as necessary. Complex PC-based control algorithms reduce the powerful forces acting on the rotor, the turbine, and the remaining structure when movements along the vertical axis occur. This high-performance system combination ensures controlled start-up and prevents play in the tower.
