MOVING THE FUTURE

Moving forward Wind turbines from Schuler

Schuler approaches the wind energy market with a strong

foundation and core competencies in innovation, quality and

engineering expertise.

In cooperation with creative and high-performing partners, we

have developed a direct-drive wind turbine offering 2.7 MW.

It is certied to IEC WT01, IEC 61400-1 (Ed.2).

MOVING THE FUTURE

Schuler wind turbines profitable and cost-effective

Our innovative wind turbine driveline concept is designed with

a direct drive (without a gear unit) for a 2.7 MW permanent-

magnet synchronous generator. This design achieves excellent

efciency, especially operating under partial-load, combined

with reduced maintenance requirements throughout its entire

service life.

The overall design offers a variable-speed generator / converter

system with electrical adjustment of individual blades, and

performs with maximum energy yield and high efciency. The

ground-breaking concept, which is engineered with an innovative

design, allows Schuler SDD 100 systems to be optimally inte-

grated into the power grid. The converter concept ensures power

system compatibility, permitting powerful and high-speed active

and reactive power control, thereby providing the prerequisites

to maintain power system stability.

Permanent-magnet synchronous generatorHigh partial-load efciency

High power ux density

Compact construction

Closed cooling circuit; no contact between the electrical

system and outside air

Advance-controlled power converterStatCom function (reactive power infeed possible even

without active power)

Power system stabilization (dynamic frequency and voltage

stabilization)

Low-voltage ride through

The high-performance turbine meets the requirements of

EEG 2009 and the SDL-WindV regulations.

EEG (Renewable Energy Act) requirements 2009, SDLWindV

(System Service Ordinance)The Schuler concept offers outstanding properties for riding

through voltage dips during power system disruptions. Not only

can it cope with critical situations caused by power system

short circuits or supply bottlenecks, but it can also perform

reactive power management and voltage control.

Easier maintenanceAccess to the hub and spinner via hollow axle shafts for

servicing the pitch drives

Maintenance-free permanent-magnet synchronous generator

without sliprings / brushes

Straightforward installationIntegration of all components in assembly units (< 90 tons)

Low installation / removal costs thanks to exchangeable power

electronics and transformer in the base of the mast

Low noise emissions

Increased availabilityLess likely to suffer from malfunctions because there is no

gear unit

Fewer anti-friction bearings

No gearing and fewer components exposed to tribological

stresses

Faster startup at low temperatures

Lower friction effects in the driveline

Electric pitch adjustment

Low lifecycle costsLower maintenance expenses

No oil change, no oil lter replacement

Grease lubrication for anti-friction bearings

Lower condition monitoring expenses

Fewer vibration sensors due to smaller number of bearings

No need for lubrication sensors (temperature, pressure,

particles)

Less need for auxiliary power units and backup power supplies

No crane and repair costs for gear unit renewal

More favorable insurance terms

Assembly capacityIn one of the biggest assembly halls in Europe, Schuler assembles

large systems for customers all over the world. Further assembly

capacity is available in Germany, China and Brazil.

A global player with local facilitiesSchuler has facilities in 40 countries.

Engineering expertise and project management experience

Schulers project management team offers a winning combination

of technical, professional and organizational skills

Service performance is everythingSchuler has more than 900 service staff at work around the world.

They ensure that more than 150,000 installed machines operate

and perform efciently.
