What is the minimum diameter of a wind turbine blade?

The power of a wind turbine is not only determined by the size of the blades, but also by the speed of the generator. If the rotation speed of the blade is very high (assuming it is infinitely high), then the generator it drives can be enough for a family.

So, to determine if the power of a wind turbine is sufficient, the first thing to consider is not the size of its blades, but the amount of power that the blades (which drive the generator) have can produce when rotating; and because the wind There is a reduction in efficiency when the blades are transmitted to the generator; the generator also has its own efficiency issues, finally, consider the total power of household appliances; If your wind turbine can produce that much power, it could be enough to power a house.

How many meters is the blade of a large wind turbine?

The length can reach 108 metersres, 111 meters, even 115 meters.

The record for the longest wind turbine blade has been broken several times. Indeed, the length of the blades of a wind turbine depends on the rated power of the entire unit and the conditions of the wind field.

For example, for a 2 MW wind turbine, the blade length range is 48 to 59 meters; for a 3 MW wind turbine, the blade length range is 44 to 59 meters for wind turbines of 5 MW and above; The blade length range is 62 to 75 meters. This data may change with technological advancements and market demand.

For example, Mingyang Intelligent announced the development of MySE16.0 242 offshore models, with a single power of up to 16 megawatts and a planned blade length of 118 meters. China Shipping also announced the development of a 16-megawatt offshore wind turbine, with blade lengths expected to exceed 125 meters. All this shows that the pawind turbines are multiplying rapidly and the era of “large” blades has arrived.

40 meters to 90 meters. According to the CCTV website, the length of wind blades ranges from 40 meters to 90 meters. Wind turbines convert wind energy into mechanical work. Mechanical work causes the rotor to rotate and produce alternating current. It includes wind turbines and generators. devices), steering (tail), tower, speed limit safety mechanism and energy storage device and other components.
