Yes, the cabin can be rotated and is always facing the wind. The technical term is yaw. Of course, the nacelle will not always rotate in one direction, such as clockwise or counterclockwise. If the wind direction is unlucky, it will always move in the same direction. The fan will rotate at most seven to eight hundred degrees, and it will also have to actively rotate, which is called unmooring. . Prevent the cables inside from being pulled off.
Wind turbines are electrical equipment that convert wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a director (tail), a tower, a speed limiting safety mechanism, and an energy storage device.
Extended information:
Broadly speaking, a wind turbine is a heat energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power uses natural energy. It is much better than diesel power generation. But if it is used in an emergency, it is still not as good as a diesel generator. Wind power is not considered a backup power source, but it can be used for the long term.

The intensity of wind energy used is usually expressed by wind power level.
The level of wind force can be estimated from the way objects on the ground or sea surface are blown by the wind. The current internationally accepted wind power estimate is based on the Beaufort wind scale. Beaufort was a British admiral who pioneered the wind classification standard in 1805. At first it was only used at sea, and later also on land. It has been revised many times and has become the common wind level today. The empirical relationship between actual wind speed and Beaufort wind level is:
V= 0.836 * (B ^ (3/2))
B is Beaufort wind level, V is wind speed (unit: m/s)
Generally speaking, the starting wind speed of the wind turbine is 2.5 m/s. When you feel the wind on your face and the leaves are shaking, it will start to generate electricity. When the wind speed reaches 28~ At 34 meters/second, the fan will automatically detect and stop running to reduce damage to the receptor itself.
Wind energy
Wind energy: the kinetic energy generated by the flow of large amounts of air on the earth's surface. Due to the different temperature changes and the different water vapor content in the air after being irradiated by the sun, the air pressure in different places on the ground is different. In the horizontal direction, high-pressure air flows to low-pressure areas, which is the formation of wind. Wind energy resources are determined by wind energy density and available wind energyYearly accumulated hours. Wind energy density is the power of wind available per unit windward area, and is directly proportional to the cube of wind speed and air density.
