Whether from general pollution concerns, carbon emissions, rising fuel prices, or a desire for energy independence, renewable energy has become the energy of choice for consumers. Renewable energy from wind has been at the forefront of this movement due to its economical yields and zero carbon footprint.
To continue to make “green” energy more available, the industry needs new and advanced technologies that lower both wind park startup, operating and maintenance costs while boosting energy yields. They need to lower the Levelized Cost of Electricity (LCOE).
Doubly-Fed Induction (DF)
Referred to as DFIG, doubly-fed induction generators have been the most widely used technology in wind turbines. This solution has a multi-phase wound rotor and a multi-phase slip ring assembly with brushes for access to the rotor. Designs without brushes (brushless) have been introduced.
Full-Scale Conversion (FC)
In a full-scale conversion drivetrain, the wind turbine gearbox is protected because the generator is not connected directly to the grid and therefore subjected to grid faults that can create excessive stress on the drivetrain. A highly efficient solution that also provides better power quality to the grid.
HTS Direct Drive (HTS DD)
AMSC’s direct drive superconductor generator design utilizes power dense superconductors to create a smaller, lighter and more efficient machine that produces higher power ratings and energy yields while lowering installation, operating and maintenance costs.
SuperGEAR™ SG System
AMSC’s patented SuperGEAR drivetrain provides the wind turbine’s generator with a direct connection to the utility grid. With no converter or transformer required, it produces the best possible power quality available on the global market. This drivetrain solution enables smaller and lighter nacelles with higher and more stable efficiency and reliability – characteristics that are particularly crucial for offshore wind installations.
