The A-2000 is is a
three-blade, horizontal-axis turbine,
designed for optimal use of wind energy on
all types of sites.
It has an optimized torque control system
combining variable-ratio superposition gear
(SPG) with individual pitch control of the
blades. This means that it can be operated
at optimum aerodynamic efficiency throughout
the whole operational range. The gearbox
ratio is controlled via a highly responsive
electronic hydraulic governor system which
maintains synchronous generation while
controlling the dynamic loads in the drive
train. This combination of SPG and pitch
control allows the wind turbine to be
operated from 3 m/s.
The A-2000 features robust gearbox
construction with integrated rotor shaft,
making the unit more compact and silent.
* Superposition gear (SPG) drive train
concept provides full control of variable
speeds
* Stand-alone operation enabled by
synchronous generator, which requires no
power
* No generation of harmonics into grid
* High short-circuit current capability
* Synchronous generator operates at high
voltage (6.3 kV and greater), enabling a
reduction in cable size.
