Innovation and transformation of wind power generation

Brother, aren't you in the industry?

There are virtually no problems with the Danish horizontal axis wind turbine, but the vertical axis is a concept that the Americans are currently demonstrating.

The pitch and yaw function is basically mature. The starting wind speed is not as high as you think. The number of blades is 3 and there is nothing that can be changed.

The foundation generally uses a ground anchor cage + concrete + pressure grout or other piles. How to make the honeycomb you are talking about?

Isn't the elastic device on the blade you're talking about Pitch? It has been widely used for a long time.

If you're talking about a small off-grid fan for your own home, pretend I didn't mention it.

Large off-grid power plants and large grid-connected power plants

Use levitation technologyn magnetic, combined with the magnetic force of supermagnets, to suspend the motor coils in a certain space. Without any mechanical friction, the wind causes the motor to rotate and cut the magnetic lines to generate alternating current, which is stored in the battery.

This scientific research achievement received design and utility model patents issued by the National Intellectual Property Office on December 31, 2010 and January 20 this year, respectively. According to experts, compared to traditional horizontal axis wind turbines, magnetic levitation wind turbines are more expensive, but their advantages are very significant: firstly, the former has tail fins, which should rotate the wind turbine according to changes wind direction; relies on The gyroscopic wind wing rotates without changing axis when the wind direction changes. Second, the first one is noisy andcannot overcome the jitter caused by varying wind direction. The motor and blades fall off easily and the parts need to be replaced every 3 years, while the second works stably, without noise, and various parts are damaged. Long service life, not easy to fall off, and can work continuously for more than 20 years. Third, the first requires a large, open and unobstructed space; while the second requires little space and can be used in urban areas, suburbs and coastal mountainous areas. Last but not least, the first one starts with a wind speed of at; at least 2.5 m/s, while the latter only. It can start with a wind speed of 1 m/s and can work normally if the wind speed exceeds 40 m/s. The higher the wind speed, the higher the power generation efficiency and the higher the wind speed. electricity production can be increasedincreased by 35% compared to the previous one.
