Changes in wind speed and direction have a greater impact on the energy production of wind turbines. Generally, the taller the tower, the higher the wind speed, the smoother the airflow, and the greater the power generation. The location of wind turbines must therefore be carefully considered, as each installation is different and factors such as tower height, distance from batteries, local planning requirements and obstructions such as buildings and trees must be taken into account. The specific requirements for wind turbine installation and site selection are as follows:
The recommended minimum tower height for wind turbines is 8 meters or more than 5 meters from obstacles. There must be no obstructions within 100 m of the installation. center of the installation range;
Two adjacent fans must be installed ata distance of 8 to 10 times the rotor diameter; Fan locations should avoid turbulent flow. Choose an area with a higher average annual wind speed, a more stable prevailing wind direction, and small daily and seasonal changes in wind speed;
The vertical shear of wind speed in the wind turbine height range should be small; choose locations with few natural disasters as much as possible;
Safety is the main concern when choosing an installation location. Therefore, even if a wind turbine is installed in a location where the wind speed is less than ideal, the blades of the wind turbine should not rotate during installation.
Will the location where wind turbines are installed change?
Hello, Chris Generator will answer your questions about site selection and the environment wind turbines, also called "wind energyienne". Where can the generator work continuously?:
1. Characteristics of flat land, two conditions must be met:
1. 3 to 5 km around of the selected area. Wind farm site In the scope of application, the terrain height difference is less than 60m;
2. not 3%.
Selecting the location of wind farms on flat land is relatively simple, and the arrangement of wind turbines is relatively simple. Just take into account the roughness of the ground and obstacles. upstream and downstream However, the anemometer tower should be installed in a location that best represents the wind resources of the wind farm. Avoid nearby obstacles, especially in the downwind direction of the prevailing wind direction. horizontal distance from the obstacle must be installed at a position greater than 10 times the height of the obstacle ifthe wind measurement tower is installed in a protective forest. or anti-typhoon forest, it must be installed at a height of more than 10 m.
2. Several points to pay attention to when selecting sites for complex terrain:
1. The crest should be as perpendicular as possible to the prevailing wind direction and the front. of the mountain should be far from the mountains or there should be no high mountains;
2. The top of the mountain should not be very flat and the slope should be uphill to the top of the mountain. should be as continuous as possible;
The increase in wind speed on the ridge is greater than that on the spherical mountain;
4. The increase in wind speed on steep mountains will decrease. quickly with changes in height compared to level ground;
5. The optimal slope is between 20 and 30°, occasionally encountering 30° on higher slopes.be avoided as much as possible;
6. The acceleration of wind speed with altitude on mountain ridges is not very high compared to that on flat terrain and will disappear quickly as altitude increases;
7 . Wind energy Topography adjacent to the field. has an impact on the structure of the air flow.
If you work in a wind farm, the conditions are difficult because the places with good wind resources are the grasslands of Inner Mongolia and eastern coastal areas, Xinjiang, Yunnan, northeast and other remote areas. If you work in a wind power equipment company, because these companies are machinery and equipment manufacturers, you usually need to go to wind farms located in the suburbs of cities with convenient transportation, such as Goldwind Technology, Huarui and Dong Qi, but there will be corresponding subsidiess, generally 100 yuan/day. If you work for a wind equipment parts supplier, you have fewer opportunities to travel onsite. The installation location requirements for wind turbines are as follows: 1) Abundant wind resources. Small wind turbines should generally be used in areas with abundant wind resources, that is, the annual average wind speed is more than 3 m/s and the cumulative number of annual effective wind speeds is 3 at 20 m/s is greater than 3,000 hours. (2) There is a stable dominant wind direction. Wind turbines should be installed wherever possible where the prevailing wind direction is relatively stable and seasonal changes are relatively small. (3) Small turbulences. Turbulence not only reduces the power output of a wind turbine, but also causes mechanical vibrations throughout the wind turbine. WhenIf turbulence is significant, mechanical vibrations can damage wind turbines. (4) Weather factors have little influence. Try to avoid areas where the airflow speed changes frequently and drastically to prevent the entire device from vibrating and damaging the fan. Avoid areas prone to strong winds. Strong winds are very destructive to wind turbines, so the impact of ice and sticky snow on the shape of wind turbine blades must be considered. It should be emphasized that due to differences in terrain, relief and geology, the choice of installation location requires specific analysis and please seek professional advice.
