The structure of the wind power project mainly includes the following parts:
Wind turbine generator: This is the core part of the wind power project, including blades, hub, main shaft, generator, gearbox, brake device, etc. The blades are responsible for capturing wind energy and transmitting it to the rotor shaft, while the hub is the connector between the blades and the main shaft. There are various types of wind turbine generators, including micro, small, medium, large, and megawatt-level wind turbine generators, classified according to their operating mode and the state of the rotor shaft.
Box-type substation: The box-type substation is used to boost the electrical energy generated by the wind turbine generator. There are various types of box substations, such as American, Chinese, and European types, each differing in structure, size, and price, suitable for different scenarios.
Collection lines and outgoing lines: The collection lines are responsible for gathering the electrical energy from multiple wind turbine generators and sending it to the booster station. The collection lines and outgoing lines can be in overhead or cable form, with the specific choice depending on the terrain and environmental conditions.
Booster station: The booster station further boosts the electrical energy, usually from 35kV to 110kV, and then delivers it to the user side through the grid substation. The booster station includes the main transformer and other related equipment to ensure efficient transmission of electrical energy.
Grid substation: This is the final stage where electrical energy connects to the grid, responsible for further transmitting and distributing the electrical energy from the booster station to the users.
