Goldwind 4 MW wind turbine hub height

Hello, would you like to ask how many meters is the hub height of Goldwind’s 4 MW wind turbine? The hub height of Goldwind’s 4 MW wind turbine is 90m. Goldwind’s 4 MW wind turbine has a maximum wind speed of 37.5m per second, a swept area of ​​11,595 square meters, an impeller diameter of 121.5m, and a motor hub height of 90m.

I bought a small generator on Taobao to make a wind turbine, but the magnetic resistance is a bit large and it is difficult to start. The blade diameter is 750mm. Does anyone have experience?

The wind energy utilization coefficient of the fan is expressed in CP. Theoretically, the CP will not exceed 0.593. The maximum power generation efficiency of current mainstream wind turbines (the highest utilization rate is around 10 meters/second) is generally around 0.45, while the level 7 wind is 14-17 meters/second, which exceeds the troublesome wind speed of the wind turbine. , the utilization rate will start to decrease, around 0.2-0.4. The sweep area is related to the impeller diameter. The current mainstream impeller diameters are 70, 80, 93, 105, 115 meters, etc. You can calculate the corresponding sweep area.

In addition, the current mainstream wind turbine power is 1500, 2000, 3000, 5000, 6000KW, etc., of which 1500 and 2000 account for 80%

I am engaged in wind power, and the main reason is not Your reluctance is large because you have chosen a larger motor. According to the wind energy formula

Theoretically the generator power = 0.593*0.5pAv^3*c

Wind energy conversion limit efficiency : 0.593

p: Air density

A: Sweep area

v: Wind speed

Our large fans have the ultimate efficiency It’s only about 0.43,

And if you make this blade, it looks even lower in the picture. Now even if your conversion efficiency is the highest, then back-calculate that your power is 28 watts when the wind is 6 meters, which is at 11 meters. The wind is only 174 watts, and you can find 11 meters of wind on the ground. So at 6 or 7 meters of wind, you can't even blow the windmill. The only solution is to increase the blade area
