6 FAQs about [Semi-direct drive wind turbine generator output]

How does a direct drive wind turbine work?

A direct-drive wind turbine’s generator speed is equivalent to the rotor speed, because the rotor is connected directly to the generator. As the rotational generator speed is low, designers placed several magnetic poles in the generator to achieve the appropriate high output frequency.

What is direct drive permanent magnet synchronous wind turbine?

With the continuous progress of power electronic technology and computer control technology, large-scale wind turbine can use the technology of direct driven permanent magnet wind turbines. Direct drive permanent magnet synchronous wind turbine is characterized by low speed and high torque requirements , , .

How big is a direct drive afpmg wind turbine?

However, the outer diameter of the generator is as high as 4.8 m.Kobayashi H et al. [ 8] designed a 6.5 MW direct-drive AFPMG,which has a diameter of 10 m.Too large radial dimensions has become an urgent problem for direct drive AFPMG wind turbine.

What is a wind turbine drivetrain?

This paper presents the state-of-the-art technologies and development trends of wind turbine drivetrains – the system that converts kinetic energy of the wind to electrical energy – in different stages of their life cycle: design, manufacturing, installation, operation, lifetime extension, decommissioning and recycling.

What are the advantages and disadvantages of direct-drive turbines?

An advantage of direct-drive turbines is the high efficiency of synchronous permanent magnet generators. An important fact is that due to wind inconsistency, the turbines often operate at partial loads. The efficiency of the PM generator excels even in these conditions because it continues working nearly to nominal values.

How do wind turbine generators work?

As the rotational generator speed is low, designers placed several magnetic poles in the generator to achieve the appropriate high output frequency. The there are two categories of wind turbine generators: permanent magnet generators (PMGs) and electrically excited synchronous generators (EESGs).
