What voltage supplies voltage to the yaw motor?

Explanation:
The yaw motor is part of the nacelle orientation system and is powered by the turbine’s auxiliary, or secondary, grid voltage. This is a dedicated, lower-voltage supply for control and auxiliary equipment, kept separate from the high-power power that goes to the grid from the generator. Using the secondary grid provides a stable power source for the yaw drive even as the generator’s output fluctuates with wind, ensuring reliable nacelle rotation. The primary grid voltage powers exporting energy to the grid, so it isn’t used directly for the yaw motor.
