Diameter of 95m tower

The diameter of the 95-meter tower is 156 meters. The wind power tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind turbine and absorbs the vibration of the unit. The production process of wind power towers is generally as follows: CNC cutting machine cutting, thick plates need to be beveled, plate rolling machine after rolling and forming, spot welding, positioning, after confirmation, welding of internal and external longitudinal seams, after roundness inspection, If there are any problems, perform secondary rounding. After the single-section cylinder is welded, a hydraulic group is used to perform spot welding on the roller frame. After welding the inner and outer circumferential seams, straightness and other tolerances are inspected. After the flange is welded, the welds are carried out. After non-destructive testing and flatness inspection, sandblasting and painting, the installation of internal parts and finished product inspection are completed, and then transported to the installation site.

That is, the selection of the location of the wind turbine should be based on a technical and economic comparison of several options to determine the layout plan of the wind turbines in the wind farm so that the wind farm can obtain better power generation. In addition to the distribution characteristics of wind energy resources in wind farms, unit layout also needs to consider the limitations of objective factors such as land use, villages, power facilities, and environmentally sensitive factors, the terrain conditions around the wind turbines, and the adverse effects of buildings, trees, or other obstacles. and the impact of wakes between wind turbines.

In flat terrain conditions, it is easy to meet this principle. In mountainous areas, meeting this principle is often difficult. According to the requirements of the transportation machinery and installation machinery required for the selected model, there should be enough space near the machine position to operate and place the blades and towers. The road should have sufficient slope, width and turning radius to enable the transportation machinery to reach the selected location. aircraft position. Arrange in columns parallel to the main wind energy direction and in rows perpendicular to the main wind energy direction. Rows are parallel and columns are spaced the same. The power generation is higher when the row spacing is larger than the column spacing, but the equidistant arrangement is visually better. Pursuing visual beauty will result in a certain loss of power generation, so there must be a certain balance between economic benefits and beauty.

It is worth noting that the energy loss of a multi-row and multi-column arrangement is also related to the terrain and ground roughness, so the above numbers only give us a perceptual understanding. On the one hand, considering the wake effect of wind turbines, we should make the distance between wind turbines as large as possible; on the other hand, restrictions on land use and grid connection require that the distance between wind turbines be as small as possible. According to experience, in the direction parallel to the main wind direction, the distance between wind turbines is generally maintained at a distance of 5 to 9 times the impeller diameter; in the direction perpendicular to the main wind direction, the distance between wind turbines is generally maintained at a distance of 3 to 5 times the impeller diameter. . The arrangement shown in Figure 3 takes into account many factors, and the units are arranged in a plum blossom shape.

The main wind energy direction in this area is the west and its southerly and northerly directions. Since the surface roughness of the water surface is small, the westerly wind still has high energy after passing through the water surface. In the land area on the east side of the water area, after the airflow lands, due to the increase in ground roughness, the attenuation of wind speed increases and the wind power density decreases. The south, west and north sides of the water area are all hilly areas, especially the west side of the water area.The direction of the highlands (ridges) in the side hilly area is perpendicular to the main wind direction. When the airflow flows through this area, it produces a strong climbing acceleration effect as the ground rises. The wind speed reaches the maximum value at the top of the mountain, so this mountaintop area is ideal. cloth machine area.
