Vestas Yaw Power Backup System Extending turbine yawing capabilities to grid loss events Benefits of Vestas Yaw Power Backup System: • Maintain the yawing functionality of turbines in grid loss events • Full integration with the Vestas SCADA system The Vestas yaw system continuously controls the position of the nacelle to maximise the turbine performance depending on changing wind conditions. When high wind speeds trigger a cut-out event, yaw systems also become essential mechanisms to safeguard the structural integrity of the turbine by yawing the nacelle towards the wind direction. In rare extreme climate events power from the main power grid can be lost, preventing the stand- ard yaw system to work. With the Vestas Yaw Power Backup System the yaw system can operate independent of grid power.
