eno 126 | enovation for efficiency

Leading EdgeThe optimized aerodynamic rotor and advanced carbon fibre technology of the eno 126 are the reasons of the high-level in point of economic efficiency and charge reduction. Special innovated detailed solutions, combined with robust engine construction make the eno 126 a solid investment in the new generation of wind turbines over the long-term. With a large rotor span and a coated area of 12,500 m2² it is ideal for low wind sites. The result: with 3,500 kilowatts rated power, combined with an increased turbulence classification, make the eno 126 one of the most efficient solutions within a wind farm.

Optimised area yield

Thanks to the eno up.site®-

principle, the eno 126 sets new

standards in terms of power

plant efficiency. The carbon

fibre blade, optimized for load reduction

and wind farm operation, combined with

the turbulence-resistant design of support

structure and drivetrain components, allows

for significantly smaller distances between

wind turbines and can reduce sectoral shut-

downs. The result is maximum usage of the

windfarm and the highest yield level at less

windy sites.

High availability

The eno live.train® concept

guarantees maximum reliabili-

ty and durability for all drive train

components of the eno 126:

The maximum protection for the gearbox

is provided by a four-point bearing of the

rotor, a hydraulic gearbox suspension

without reactive forces, an active drive train

damping, a full-power converter as well

as a temperature and power controlled oil

supply system.

Excellent grid characteristics

With its well proven combinati-

on of a brushless synchronous

generator and a full-power

converter the eno 126 handles

grid faults smoothly and reliably. The wide

reactive-power range underlines the excel-

lent grid compatibility of the turbine regar-

ding flicker and harmonics with out a need

of any additional filters or compensation

systems. With these characteristics the eno

126 can easily meet all standard grid con-

nection requirements.

Complete service

Undisturbed operation, high

productivity and reliable yields:

To ensure these benefits

are sustainable, eno energy

offers a comprehensive service and

after-sales programme. The flexible full-

maintenance concept - eno complete.

care® - provides a permanent super-visi-

on of the machines, including condition

monitoring. Highly qualified on-site service

technicians ensure smooth and trouble-

free operation of the wind farm. In this way

the operating costs can be calculated for

long term. Thus, the availability is guaran-

teed at a high level.

eno live.train® Life insurance for the gearbox

The maximum protection for the gearbox is provided by a four-point bearing of the rotor, a hydraulic gearbox suspension without reactive forces, an active drive train damping, a full-power converter as well as a temperature and power controlled oil supply system.

eno split.drive® Role model for grid integration

The multiphase generator, the modular converter system and the systematic redundancy guarantee optimal grid support with maximum availability from the generator winding to the converter.

eno blade® Efficiency redefined

The pioneering rotor blade design minimises loads and maximises the turbulence resistance to achieve an extraordinarily high efficiency and maximum profit of the wind farm.

eno ops.control® Optimisation at a click

The solution of an integrated control system based on an open, web-based SCADA connection controls all process sequences - from operational management via pitch control to wind farm networking - and enables reliable self-optimisation.

eno pitch.control® Safety meets efficiency

State-of-the-art AC drive technology meets safety level of traditional DC systems. The redundant converter topology ensures the optimum pitch of the rotor blades at all times according to the latest safety guidelines.

ns.It is our goal to make wind energy more

efficient. Economic success of renewable

energies and growing importance of climate

protection go hand in hand. eno energy has

already planned and installed a large number

of wind farms all over Europe. With this

experience we designed the 2 and 3.5 MW

platform to achieve maximum output out

of the wind farm. Therefore we offer the

most efficient solution for each location.

Efficient wind farms. For a clean future.
