No. Wind power poles placed in tree fields are national facilities after calculation by relevant departments. Moving them will affect the power generation efficiency and cannot be requested to be moved. Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity.
First of all: According to the analysis and calculation of my colleagues, polygons save more material when using the same strength. It can also be said that polygons have greater strength when using the same materials. However, the former does not save much material, and the strength of the latter does not increase much. In fact, it can also be seen that except for the truss type (which is relatively rare now) and the mast type of small wind turbines, the towers of mainstream large wind turbines are all vertebral tubular. Moreover, the domestic production of spinal canal towers is relatively mature.
Then, the tower height of large wind turbines (1-3MW) is usually (60 meters-90 meters) and is generally composed of 2-3 sections of tapered tubular steel towers (85 meters should be 3 sections). Each layer is connected with high-strength bolts in the form of internal flanges. Each tower section is welded from several conical sections with different wall thicknesses based on strength analysis, modal analysis and actual conditions. Each flange is usually forged in one piece, the entire tower welding is very strict (the standards I am talking about must comply with DIN****) and almost all welds require flaw detection.
Also, usually each section of the tower of a large wind turbine is not in the form of a spiral, but each small section is rolled out separately.
The 2MW unit at my place including the whole unit has just been completed. I participated in the proofreading of most of the towers, but there are still many things that need to be learned and deepened. As for the analysis mentioned above, a colleague of mine calculated it specifically, but I don’t know whether it is accurate or not, because I didn’t think about it and calculate it myself, but just reviewed the dimensions.
That’s it. I wish you good luck.
In addition, the price comparison between polygons and spinal canals is also relative. For example, if I am looking for a manufacturer to make towers in the Shenyang area, if the quantity is small, I may not be able to go to a professional wind power tower production site, while nearby manufacturers specialize in making towers. Polygonal steel towers (such as those used in the power industry although they also provide conical towers), then the polygonal towers I purchased elsewhere are cheaper than the tapered tubular towers. The difference is about more than 8,000 per ton and more than 10,000 per ton.
