How many meters are the blades of the wind turbine?

Introduction Wind turbine blades have different power lengths and different power lengths. If the wind power is a 1.5 MW wind turbine, the length of the blades is between thirty-four and forty-five meters; if it is a 2 MW wind turbine, the blade length range is: forty

How many meters are the blades of the wind turbine?

Different powers have different lengths. If the wind power is a 1.5 MW wind turbine, the length of the blade varies from 34 to 45 meters; if it is a 2 MW wind turbine, the length of the blade varies from 48 to 59 meters; if it is a 3 MW wind turbine, the length of the blade; ranges from 44 to 59 meters; For wind turbines 5 MW and above, the blade length range is: 62 to 75 meters, with different power lengths. Wind turbine blades are one of the essential components of wind turbines, accounting for approximately 15-20% of the total wind turbine cost. The quality of its design will be directly linked to the performance and benefits of the wind turbine.

The largest is 5 MW in Denmark and one in China. Generally, 2 MW, 1.5 MW or less 0.8 MW are used in China.

Formula for calculating electrical power: P=W/t =UI.

In a purely resistive circuit, according to Ohm's law U=IR and substituted by P=UI, we can also obtain:P=I2R=(U2)/R.

In dynamics: Power calculation formula: 1.P=W/t (average power) 2.P=FV; P=Fvcosα (instantaneous power).

Detailed information:

The most powerful machine is the engine, and the power of the motor is determined by The torque is calculated, and the calculation formula is quite simple: Power (w) = 2π × Torque (Nm) × Speed ​​(rpm)/60 After simplified calculation, this becomes: Power (W) = . Torque (Nm) x Speed ​​(rpm) /9.549.

Because of the difference between the imperial system and the metric system, the definitions of horsepower are fundamentally different. British horsepower (hp) is defined as a horse pulling a 200 pound (lb) object 165 feet (ft) in one minute.

After multiplication, this equals 33,000 lb-ft/min; while the metric definition of power (PS) is that a horse can pull a 75 kg object 60 meters in one minute, afters multiplication, this is equivalent to 4,500 kg. g.m/min.
