What are the requirements for choosing the installation of wind turbines?
Hello, would you like to ask what are the basis for site selection of Fenghuang Mountain Wind Farm? The Phoenix Mountain Wind Farm site selection basis is as follows:
1. Wind resources: Wind power generation requires relatively stable and sufficient wind resources. Therefore, the site selection of the Phoenix Mountain Wind Farm must take into account local meteorological conditions such as wind speed and direction. Generally speaking, the greater the wind speed and frequency, the better the wind energy utilization effect.
2. Terrain conditions: Terrain is one of the important factors affecting the utilization of wind energy. When selecting the site for the Phoenix Mountain Wind Farm, factors such as mountain topography, altitude, and surrounding buildings need to be taken into consideration to determine the best wind energy utilization method and equipment selection.
3. Environmental protection requirements: As a clean energy source, wind power generation must meet environmental protection requirements. The site selection of the Phoenix Mountain Wind Farm needs to comply with relevant environmental protection regulations, take into account wind turbine noise and the impact on wildlife, and rationally plan roads and other infrastructure to reduce the impact on the environment.
4. Economy: The cost of wind power generation construction is relatively high, and economic issues need to be taken into consideration when selecting sites. When selecting the location of the Phoenix Mountain Wind Farm, factors such as investment cost, grid connection, operation and maintenance need to be comprehensively considered., to ensure the economic feasibility of wind power projects. To sum up, the location selection basis for the Phoenix Mountain Wind Farm is multi-faceted. It should not only take into account wind resources and terrain conditions, but also follow the principles of environmental protection and economy. At the same time, during the site selection process, it is also necessary to understand relevant local regulations, policies and technical standards to determine the best site selection plan.
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 must be enough space near the machine position to operate and place the blades and towers. The road must 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 highlands (ridges) in the hilly area on the west side of the water area are perpendicular to the main wind direction. When the airflow flows through this area, it creates strong turbulence as the ground rises. Climbing acceleration effect, the wind speed reaches the maximum value in the mountain top area, so the mountain top area is an ideal cloth machine area.
