Hello, Chris Generator will give you the answer to the site selection and environment of the wind turbine, that is, "where can the wind turbine rotate continuously":
1. The characteristics of flat terrain require Meet two conditions:
1. Within 3~5km of the selected wind farm site, the terrain height difference is less than 60m;
2. Within 3~5km The maximum slope does not exceed 3%.
The location selection of wind farms on flat terrain is relatively simple, and the layout of wind turbines is relatively simple. You only need to consider the roughness of the ground and obstacles upstream and downstream. However, the anemometer tower should be installed at a location that best represents the wind resources of the wind farm. Avoid obstacles around. Especially in the downwind direction of the dominant wind direction, the horizontal distance to the obstacle should be installed at a position that is more than 10 times the height of the obstacle. For example, if the wind measurement tower is installed in a protective forest or anti-typhoon forest, it should be installed at a height of the forest. More than 10m.
2. Several points that should be paid attention to when selecting sites for complex terrain:
1. The ridge should be as perpendicular to the dominant wind direction as possible, and the front of the mountain should be far away from the mountains or there should be no tall mountains. Ridge;
2. The top of the mountain should not be very flat, and the rising slope to the top of the mountain should be as continuous as possible;
The increase in wind speed on the ridge is higher than that on the spherical mountain;
4. The increase in wind speed on steep mountains will decrease quickly with height changes compared with flat land;
5. The optimal slope is between 20 and 30°, and occasionally encounters 30° on higher slopes. Hillsides should be avoided as much as possible;
6. The acceleration of wind speed with height on mountain ridges is not very high compared with that on flat land, and will disappear quickly as height increases;
7. Wind power Topography adjacent to the field has an impact on airflow structure.
