The Future of Wind Turbines: Comparing Direct Drive and Gearbox
Apr 7, 2020 · Two types of wind turbines share the focus of current development efforts, and are competing to be recognized as the dominant design: the gearbox, and the direct-drive wind turbines. This article will examine both types of turbine, and discuss the advantages and disadvantages, as well as tackle their potential to become the dominant type of ...
Advanced Wind Turbine Drivetrain Trends and Opportunities
Jul 3, 2019 · Having all of those moving parts makes the gearbox one of the highest-maintenance parts of a wind turbine. One alternative is to use a “direct drive” generator that can generate electricity at much lower speeds. Direct drive systems do not require a gearbox and therefore have fewer moving parts.
Wind turbine technology battles: Gearbox versus direct drive
Apr 1, 2020 · This paper studies the battle between two types of wind turbines, the gearbox wind turbine and the direct drive wind turbine. Applicable determinants that affect technological dominance for the wind turbine drive trains case are identified.
How a Wind Turbine Works - Text Version | Department of Energy
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.
Direct Drive vs. Gearbox: Progress on Both Fronts - Power Engineering
Mar 1, 2011 · For years, wind turbine manufacturers have been searching for ways to make direct drive turbines competitive with gearbox turbines. Direct drive technology has been praised for its design,...
Direct Drive Wind Turbines - SpinningWing
A direct drive wind turbine converts rotor rotation to electrical power directly, without the use of a gear box. Traditional wind turbines use gearboxes to step up the rotational speed (about 100x) from the rotor to the generator, which makes electrical power.
Direct drive technology - EWT
With turbine power outputs ranging from 500kW to 1MW, and rotor tip heights from 61 m to 100 m, our DIRECTWIND turbines are designed to deliver maximum wind energy yield and a low total cost of electricity for all types of wind conditions (IEC class I, II and III) and in any location.
How Do Wind Turbines Work? | Department of Energy
The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity. Types of Wind Turbines
An Exclusive Look at the New Siemens 3-MW Direct-Drive Turbine
Dec 3, 2009 · An Exclusive Look at the New Siemens 3-MW Direct-Drive Turbine. Brande, Denmark [RenewableEnergyWorld.com] Little over a year after Siemens erected its first 3.6-MW direct-drive “Proof of Concept” wind turbine, this November the company presented a new rather different 3-MW direct-drive concept.
State-of-the-Art and New Technologies of Direct Drive Wind Turbines
Feb 22, 2017 · Direct drive wind turbine concepts with gearless drive trains have been developed and improved in the last 20 years. Compared to turbines with gearboxes, reliability and efficiency are increased and cost for maintenance and downtime is reduced.
