Wind field conditions of Caofeidian wind farm construction

According to Baidu Library, the wind conditions of Caofeidian wind farm construction are as follows:

Meteorological conditions:

1, the wind energy quality should be high. The first condition of wind farm location must be abundant wind energy resources. Only when the annual average wind speed is above 5m/s, the effective wind hours at a height of 30m are above 6000h, and the effective wind energy density is above 240w/m 2, is it suitable to build large-scale wind farms.

2. The wind direction of the wind farm site is stable. Stable wind direction can not only improve the utilization rate of wind energy, but also prolong the life of wind turbine.

3. Turbulence degree of wind farm should be very small.

4. Wind farms have fewer natural disasters. Strong wind, hail, thunderstorm, earthquake, etc. Will have an impact on wind turbines.

Social natural conditions: 1. The terrain of the wind farm should be relatively flat, with good geological conditions, so as to facilitate civil construction.

2. Convenient transportation. It is necessary to consider whether the equipment supply of the proposed wind farm and the transportation of main building materials are convenient. Whether it is conducive to the construction and transportation of large cranes and flatbed cars.

3. The wind farm should be as close as possible to the power grid access point. For example, it is close to the existing 10KV and 66KV substations and lines, so as to reduce the power loss and the cost of the transmission project. Try to occupy less cultivated land and reduce ecological damage.

4. Surrounding environment. The construction of wind farms will generally affect the normal life and migration of birds. In order to protect the ecology, the site selection should try to avoid bird flight routes, migratory birds and animal habitats, and stay away from nature reserves, military facilities and densely populated areas.
