According to data from Baidu Wenku, the wind field conditions for the construction of Caofeidian Wind Farm are as follows:
Weather conditions:
1. The quality of wind energy must be. high. The primary condition for a wind farm site must be abundant wind energy resources. The annual average wind speed is more than 5 m/s, the effective wind hours at a height of 30 m are more than 6,000 hours, and the effective wind power density is more than 240 W/m^2.
2. The prevailing wind direction at the wind farm site is stable. Stable wind direction can not only increase the utilization of wind energy, but also extend the lifespan of wind turbines.
3. The degree of turbulence in wind farms must be low.
4. There should be fewer natural disasters at wind sites. Strong winds, hail, storms, tremorsts of earth, etc. will affect all wind turbines.
Social and natural conditions: 1. The terrain of the wind power site should be relatively flat and the geological conditions should be good to facilitate civil construction.
2. Convenient transportation. It is necessary to determine whether the provision of equipment and transportation of key construction materials of the proposed wind farm is practical. Is it suitable for building and transporting large cranes and flatbed trucks?
3. Wind farms should be as close as possible to the grid access point. For example: near existing 10 KV and 66 KV substations and lines to reduce power loss and delivery project costs. Occupy as little cultivated land as possible to reduce ecological damage.
4. Surrounding environment. The construction of wind farms generally affects the normal life and migration of birds and birds.he birds. In order to protect the ecology, the site should try to avoid bird flight routes, migratory birds and animal habitats, etc., and stay away from nature reserves. military installations and densely populated areas, etc.
Personally, I think the prospects for small wind turbines are pretty good! After all, the capacity of Category I and II wind farms in China is limited, and not everyone can participate. Small wind turbines can operate on Category III or even Category IV wind farms. They have a wide range, low investment, low installation and maintenance costs and immediate effects. The village can accommodate the installation of three or five.
As for technical bottlenecks, I still think cost is an issue. In the future, installation, operation and maintenance costs could be the coststs. Also, the starting wind speed is a big problem. If Xiaofeng can start, operating costs may be increased. If connected to the grid, consideration should also be given to the low voltage pass-through capability, which is very hot at present.
