When selecting a site, you must first determine the area from a macro perspective, then conduct testing and assessment of regional wind energy resources. Particular attention should be paid to the impact of typhoons during site selection and evaluation. Powerful typhoons not only damage blades, nacelles and structural components, but also have a certain impact on generator equipment. Such as the following factors:
1. The geological structure of the seafloor, the depth of the seafloor and the maximum wave level
1. Sea wind is one of the important factors driving the cost of offshore. wind energy. Choose geology Building wind farms in sea areas with good conditions is not only conducive to construction, but also reduces costs and prevents geological disasters.
2. The depth ofwater is also one of the important factors that affect the total project cost. For example, the construction of wind turbine foundations and the laying of cables are all affected by excessive water depth. difficult construction site.
3. Waves contain a large amount of kinetic energy and pressure, which produce large repeated loads on the structure and have a serious impact on the service life and dynamic behavior of the structure.
2. Seismic and tectonic hazards
There are some minor tectonic faults along the Chinese coast. Earthquakes caused by plate movement along faults will cause serious damage to the survival of offshore wind power. farms. When selecting a site, you should have a detailed understanding of the appropriate spacing distance of geological faults, information on the risks of seismic activity in the sea, etc. Conflictts of use of maritime zones
Restrictions and restrictions on the use of maritime zones cannot be ignored during the process of selecting a site, as they can sometimes conflict with other industries , other uses, etc.
3. Environmental constraints
Wetlands and shallow water areas are the main areas of activity for wading birds and waterfowl. The development of these areas will have harmful effects on the animal ecosystem. and plants.
4. Port
The supporting parts and equipment of the wind farm will be placed in the port and sent to sea. Therefore, the port plays an important role at the beginning. the development of offshore wind energy.
Fifth, the electricity network
Considering the economic and technical factors related to the construction of transport equipment, choose an area close to the network access point to connect to the resau is the preferred option.
