When selecting a site, you must first determine the area from a macro perspective, and then conduct testing and evaluation of regional wind energy resources. Attention should be paid to the impact of typhoons during site selection and assessment. Strong 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 seabed, seabed depth and maximum wave level
1. Sea wind is one of the important factors causing the cost of offshore wind power. Choose geology The construction of wind farms in sea areas with good conditions is not only conducive to construction, but also reduces costs and prevents geological disasters.
2. Water depth is also one of the important factors that affect the total cost of the project. For example, the construction of wind turbine foundations and cable laying are all affected by water depth. Excessively deep water makes construction difficult.
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 life and dynamic behavior of the structure.
2. Earthquake and tectonic risks
There are some minor tectonic faults along the coast of China. Earthquakes caused by plate movement along the faults will cause great harm to the survival of offshore wind farms. When selecting a site, you should have a detailed understanding of the appropriate distance between geological faults, seismic activity risk information in the sea, etc. Conflicts in the use of sea areas
Restrictions and restrictions on the use of sea areas cannot be ignored during the site selection process, as they may sometimes conflict with other industries, other uses, etc.
3. Environmental constraints
Wetlands and shallow water areas are the main activity areas for wading and near-water birds. The development of these areas will have adverse effects on the ecosystem of animals and plants.
4. Port
The parts and supporting equipment of the wind farm will be placed in the port and sent out to sea. Therefore, the port plays an important role in the early stage of offshore wind power development. .
Fifth, power grid
Considering the economic and technical factors of building transmission equipment, choosing an area close to the grid access point to connect to the grid is the preferred option.
