Where wind power is installed, it represents the development and utilization of renewable energy and the beginning of clean energy replacing traditional energy. Wind power has the advantages of environmental protection, renewable and distributed power generation, and is an important choice for the development of renewable energy.
The places where wind power generation is installed are generally in places with abundant wind resources, such as coastlines, mountains, plains, etc. When selecting a site, factors such as wind resource conditions, environmental impact, construction cost, construction time, and equipment reliability must be considered to ensure power generation efficiency and economic benefits.
Where wind power is installed, it not only represents the development of renewable energy, but also provides an important basis for regional economic and social development, such as increasing local employment rate, promoting local economic development, improving local environment, etc. .
When selecting a site, the area must first be determined from a macro perspective, and then the regional wind energy resources can be tested and evaluated. 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.
