Explore the introduction of Wind Power Plants

Wind power generators have doubly-fed and direct-drive types, as well as other semi-direct-drive structures. Introduce the composition of the doubly-fed Wind Power Plant, and then give a brief introduction to the direct drive unit. The semi-direct drive feeling is a compromise between the two methods.

Double-fed Wind Power Plant

It is mainly composed of generator, converter, gearbox, main shaft, hub, pitch system, blade, yaw system, tower, foundation, etc.

The components of Wind Power Plants are more organized than I said.

The principle of double-fed Wind Power Plant.

The principle of the generator.

Foundation: the foundation and installation plane of the tower.

Tower: A section of the tower is on the vehicle. Generally, a tower consists of three different cylinders, and the lower middle and upper are assembled as a tower.

Cabin base: You can see the two gearmotors and gears on the front, which is part of the yaw system. It is used to drive the entire nacelle assembly in relation to the direction of the wind.

This is a gearbox used to increase the speed of about 20r / m to the speed suitable for the generator, about 1200-1800r / m. The internal speed is increased by two-stage planet + one-stage gear transmission.

This is the main shaft, which is used to connect the blade assembly and the reduction gearbox to transmit torque.

The main shaft and the reducer are matched by an expansion sleeve, and then they are fixed on the nacelle base.

Wheel hub: a wheel hub with a pitch bearing and a bearing lubrication system installed inside.

Pitch system in the hub, including pitch drive, battery, control cabinet, etc.
