6 FAQs about [Direct drive wind turbine power generation principle diagram]

How does a direct drive wind turbine work?

Direct-drive turbines simplify nacelle systems and can increase efficiency and reliability by avoiding gearbox issues. They work by connecting the rotor directly to the generator to generate electricity. Figure 23. Direct-Drive Offshore Wind Turbine

Are direct drive wind turbine generators better than geared generators?

A quantitative comparison of DFIGs, synchronous and PM generators is listed in Table 1. It can be seen that direct drive wind turbine generators are larger in size but shorter in length compared to geared counterparts.

How does a geared wind turbine work?

In a geared wind turbine, the generator speed increases with the gear ratio so that the reduc‐tion in machine weight is offset by the gain in gearbox weight. For instance, the wind tur‐bine operates at a speed of 15 rpm and the generator is designed to operate 1200 rpm (for 60 Hz) .

What is the difference between upwind and downwind turbines?

Upwind turbines—like the one shown here—face into the wind while downwind turbines face away. Most utility-scale land-based wind turbines are upwind turbines. The wind vane measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.

How does a wind turbine work?

Conclusion: A wind turbine only operates when the wind is blowing, and understanding how a wind turbine works means understanding the aerodynamics of the wind and blades, while also knowing how a turbine generator creates electricity. At its most fundamental roots, a wind turbine works by allowing wind to rotate a turbine generator.

What are the disadvantages of a direct drive turbine generator?

Nonetheless, a drawback of the di‐rect drive is associated with the low operating speed of the turbine generator. As the nomi‐nal speed of the machine reduces, the volume and weight of its rotor would increase approximately in inverse proportion for a given power output.
