The G9X platform offers a number of
advantages for developers with a portfolio
of projects with different wind regimes:
o It optimizes stock of spare parts
o All operating procedures (logistics, erection,
operation and maintenance) have been optimized
through our long track record and applied by Gamesa’s
own personnel and subcontractors for all models in the
platform
o Maximizes the efficiency of training
o Provides additional flexibility to the O&M workforce
o Improvements developed for one model can be
easily implemented in the others

BLADES
ADVANTAGES
CHARACTERISTICS
o
o
o
Blades: 39m for G80-2.0 MW, 42,5m for G87-2.0 MW, 44m
for G90-2.0 MW and 47,5m for G97-2.0 MW
State-of-the-art manufacturing process: manufactured from
organic matrix composite material, with carbon or glassfiber
reinforcement
Lightining protection system
o
The structure of each blade consists of two shells glued to
a spar or internal beams
o
Innovative airfoil for new G97 that minimizes noise
o
Lighter blades maintaining stiffness which reduces
loads transmitted to the entire system
o
High energy production and minimum noise level
thanks to optimized airfoils
o
The blade is designed to fulfill two basic functions:
structure and aerodynamics
o
Easier maintenance
11
Gamesa G9X general characteristics
Technological highlights
DRIVE TRAIN
ADVANTAGES
CHARACTERISTICS
o
Main shaft supported on two bearings
o
3-stage gearbox with 2 parallel shafts and one planetary
stage.
o
High-speed shaft connected to the generator by means of
a flexible coupling with a torque limiter system
Torque arms are used to attach the gear box to the frame
by means of shock absorbers
The gearbox has a lubrication system which permits
attaining a degree of oil purity of up to 3µm, which
reduces the potential number of malfunctions.
o
o
o
Main shaft design prevents any load except the
torque from being transmitted to the gear box, which
minimizes the occurrence of any problems with this
component.
o
Gear box is allowed to be disassembled without the
need to take apart the main shaft.
o
Flexible coupling prevents overloading the
transmission chain.
Thanks to the modular design of the power train, the
weight of the gear box is borne by the main shaft,
while the shock absorbers joined to the frame react
to any torque, preventing the gear box from rotating
and any undesired charges on the gear box.
o
12
Gamesa G9X general characteristics
Technological highlights
ACTIVE YAW
CHARACTERISTICS
ADVANTAGES
o
4 electrical motors operated by WT controller based on
information received from the anemometers mounted on
top of the nacelle
o
Combined activation of friction bearing and retention
clamps prevents fatigue and possible damage to the
ring.
o
The yaw is active with hydraulic brake clamp that can be
regulated gradually
o
The ring is divided into 6 sectors, in order to make it
easier to repair any possible tooth damage.
o
The system is composed of 5 clamps avoid fatigues and
failures in the Yaw system.
o
o
The Gamesa Active Yaw system is submitted to accelerated
lifetime test cycles and aging tests on the Gamesa UPB
testing bench.
HALT tests ensure and improve the reliability of this
component, validating its correct design and
providing feedback on the virtual models in order to
redesign them, incorporating future improvements.
13
Gamesa G9X general characteristics
Technological highlights
PITCH SYSTEM
CHARACTERISTICS
ADVANTAGES
o
Independent hydraulic actuators for each blade that provide
a rotational capacity between -5º and 90º
o
Having an independent pitch on each blade provides
redundancy for the aerodynamic brake system.
o
The pitch system is activated during the entire time the wind
turbine operates
o
The hydraulic system has an accumulator system
that allows the blades to be turned to their feathered
position, in case of an emergency.
o
The hydraulic system provides greater activation
speed than other types of systems. Due to the
hydraulic accumulator system, no batteries are
required for operation, which increases reliability
during emergency situations.
o
o
When the wind speed is below the rated speed, the pitch
angle will be selected in order to maximize the electrical
power obtained for each wind speed.
When the wind speed is above the rate speed, the pitch
angle will be the one that provides the machine's rated
power.

ELECTRICAL SYSTEMS
CHARACTERISTICS
ADVANTAGES
o
The generator is a double-fed, 4-pole variety with a
wound rotor and slip rings. It is highly efficient and
cooled by and air-air system.
o
Optimal operation for any wind speed, maximizing
the production and minimizing loads and noise,
thanks to the variable speed operation
o
The transformer is a three-phase, dry encapsulated
model, with different output voltage options and
different apparent power ranges. It has been specially
designed for wind energy applications.
The control system allows the system to work at variable
speeds, using the rotor intensity frequency control.
o
Active and reactive power control
o
Synchronous behavior with regards to the grid.
o
The generator is protected from short-circuits and
overloads. The temperature is also continuously
monitored by sensors
o
The transformer's location in the nacelle prevents
electrical loss due to the reduced length of the low
voltage cables, and it also reduces the visual impact.
