Although there are many types of wind turbines, they can be divided into two categories: ① Horizontal axis wind turbines, the rotation axis of the wind wheel is parallel to the wind direction; ② Vertical axis wind turbines; , the axis of rotation of the wind wheel is perpendicular to the ground or the direction of the air flow. Horizontal axis wind turbine: Horizontal axis wind turbines can be divided into two types: lifting type and drag type. Lift-type wind turbines spin quickly, while drag-type wind turbines spin slowly. For wind power generation, step-up type horizontal axis wind turbines are mainly used. Most horizontal axis wind turbines are equipped with a wind-facing device that rotates when the wind direction changes. For small wind turbines, this wind device uses a tail rudder, while for large wind turbines, a tail rudder is used.wind direction detection system and a servo system are used. A wind turbine with a transmission mechanism consisting of a motor and a wind wheel in front of the tower is called a leeward wind turbine, while the wind wheel behind the tower is a leeward wind turbine. There are many styles of horizontal axis wind turbines. Some have the wind turbine blades reversed, some are installed on another tower, which can reduce the cost of the tower when the power output is certain, and some generate vortices around the wind turbine to focus . air flow. Increase airflow speed. Vertical Axis Wind Turbines: Vertical axis wind turbines do not need to face into the wind when the wind direction changes, which is a major advantage over horizontal axis wind turbines. This not only simplifies the structural design, but also reduces the gyroscopic force when thewind wheel faces the wind. There are several types of vertical axis wind turbines that use resistance to rotate. One of them is a wind wheel made of flat plates and quilts, which is a pure resistance device; the S type wind turbine has some lift, but is. primarily a resistance device. These devices have a high starting torque but a low tip speed ratio and provide low power output when the size, weight and cost of the wind turbine are fixed.
It depends on the power of the wind turbine. If the power is large, the electricity production will be significant; if the power is small, the electricity production will be low. China's largest wind turbine is 2 megawatts, with daily electricity production equivalent to 11 tons of high-quality coal.
The generator turns one or two thousand revolutions per minute, while the eoLink only generates a thousand kilowatt hours of electricity per hour. This is directly related to the unit's capacity.
For example, in a 1.5 megawatt wind turbine, the generator spins about 1,800 revolutions per minute, producing 1,500 kilowatt hours per hour, and the turbine spins about 18 times per minute.
This is related to factors such as fan type and capacity and generator speed.
For example, for a 2 MW direct drive wind turbine, its permanent magnet generator reaches the rated speed, say 17 revolutions per minute, and it takes 60/17 = 3.5 seconds to make a lap. If a 2 MW wind turbine generates electricity continuously for 1 hour at rated speed, the amount of electricity generated in 3.5 seconds is 3.5*2000/3600 = 1.94 kilowatt hours, or the amount of electricity generated in one revolution.
For dual-powered fans, this is also related to the gearbox reduction ratio.e speeds.
No, let me tell you basically, the fan is 1500 kW. If it is full, it will spin at 17 revolutions per minute. If you do the math, one rotation equals 1.47 kilowatt hours of electricity. This is only an approximation and is not exact.
