Anemometer measures the wind speed and transmits wind speed data to the controller, but wind vane measures wind direction and communicates with the yaw drive to orient the turbine properly to keep the turbine facing the wind when the direction changes. According to the wind relative speed, blades angle also changes. A blade tilting mechanism tilts the blades and guarantees a proper alignment of the blades with the relative speed.
The electricity that is produced is transformed through the cables towards the tower base, where step up transformer is located. Then electricity can be connected to the mains power, a battery bank or electricity grid to deliver electricity from supplier to consumer.
