If you work at a wind power plant and perform mechanical and electrical maintenance work, you will likely travel to the wind farm for maintenance and inspection. In this case, you will certainly have to travel frequently and for as long as possible. At the wind farm, the environment will be relatively harsh and you will have to climb high if there is a problem at any time, you will have to go to the site and the work is relatively hard. However, China's wind power industry will focus on maintenance in the future, so there is still a future for development. It depends on whether your boyfriend travels often for business and whether you're willing to spend less time and stay apart more.
First of all, your question is too general.
The wind energy that the wind turbine can absorb P=1/2 (CpρπR^2U^3). In simple terms, the wind energy absorbed by the wind turbine is proportional to the cube of the wind speed, whereCp is the wind energy utilization coefficient. And this is only the theoretical power absorbed by the wind wheel. If it reaches the generator through the transmission system, there will be a loss.
As for the actual voltage, current and power output by the generator you asked about, they are determined based on the working conditions and power characteristics of the engine. For example, for some medium-sized machines, the voltage is. 670 V at rated wind speed. The power is 750 kW. Most generators are rated between several thousand and tens of thousands of volts. After its output, it must be amplified by the transformer station and filtered to remove harmonics before being supplied to the Internet.
I hope this can help you
If you are a beginner, I suggest you buy two books,
"Wind Engineering and Industrial Aerodynamics" by He Dexin.
"Wind Energy Technology" written by Tony Burton and translated by Wu Xin and others
The question you added is that the custom lies between 10 m/s and 20 m/s, and that the electricity is produced between 20 and 30V Of course there is absolutely no problem
As for the cost, it cannot be. determined immediately If you already have a good address of use, i.e. a wind farm, it will not cost you much to produce such a small amount of electricity can use a small axis wind turbine. vertical is placed on the roof and can be directly driven. The main cost is the motor, and everything else is cheap. You complete the overall design plan, then ask the parts supplier for a price. necessary to have a tower or a large-scale lift, and it doesn't cost a lot of money
By the way, sending this small call, haha, it's not worth it, personal opinion.. I wish you good work
3000 seems a bit high. The key is that it is your own new idea. This is not a mass-produced product and the labor cost is very high.
Parts like small motors + gears + wires + bearings are relatively easy to tell, but your blades, steering gears, brake pads, etc. are relatively easy to tell. must be specially made unless you are a carpenter or lathe, otherwise. 3000 should be If you can't download it, you should save space, add a little budget, try to save as much as possible, maybe it will work, because your machine is small and the technical requirements are not not very high.
How about searching for a complete set supplier directly? There are manufacturers of complete sets of small wind turbines, some of which cost more than 2,000 yuan.
