Wind turbines are state-of-the-
art power plants: generators
are responsible for converting
wind energy into electricity.
The energy output of the plant,
in addition to external factors,
is largely determined by the
ideal design of the generator in
terms of ef ciency and guaran-
teed availability. It is therefore
important that each individual
component operates reliably
and is in full working order.
By implementing tension clamp
or “PUSH IN” connection tech-
nology, our modular terminals
and plug-in connectors ensure
permanent vibration-proof
connections and help optimise
assembly and connection
times. Our surge protection
modules safeguard the systems
against faults and failure result-
ing from lightning strikes.
Optimum aerodynamic posi-
tioning of the rotor blades is a
particularly important feature
of any turbine. As a rotating
unit built into the hub, the
highest levels of vibration and
shock resistance of the pitch
system are fundamental
requirements for the reliable
and ef cient operation of a
wind turbine.
Equipped with a die-cast alu-
minium housing, our heavy-
duty plug-in connectors offer
excellent protection against
dirt, moisture and mechanical
loads. Some of the outstanding
features of the PRO-M series of
power supply units for applica-
tions in pitch systems include
metal feet for vibration-proof
attachment and high DC input
voltages for operations in con-
junction with CAP modules.
The yaw system controls the
alignment of the nacelle in the
direction of the wind, thereby
ensuring maximum energy
output and allowing the tur-
bine to be turned “away from
the wind” when maintenance
work has to be carried out.
Trouble-free functioning of the
in-built components of the
system is essential to ensure
the exact positioning of the
turbine.
For electrical isolation and
signal conditioning, our
TERMOPTO optocouplers, in
contrast to electromechanical
relays, offer an excellent wear-
free alternative to decoupling.
TERMOPTO reduces the cost
of maintenance, increases
system availability and also
saves space in the control
cabinet, thanks to its 6-mm
terminal block format.
The bottom box houses the
essential components required
for communicating operational
data to the remote operator or
for integrating a wind turbine
into a wind farm in order to
regulate, for instance, the out-
put of the individual turbines.
Our media converters and
switches convert electrical
Ethernet signals and allow
them to be transferred along
 bre-optic cables. In doing so,
Weidmüller ensures an error-
free fl ow of data within the
wind farm. Our FrontCom
®
service interface allows you
to have easy access to the
networks, thereby eliminating
the need for you to open the
control cabinet.
The inverter unit is the link
between the generator and
the power grid. It converts the
variable rotor speeds into a
constant voltage for mains
usage. The modular, ef cient
and low-maintenance design
of the components used in
the converter facilitates quick
assembly and, in several cases,
also helps us ful l customer-
speci c assembly requirements.
Protection systems and proper
testing play a decisive role in
these applications.
POCON, our current/voltage
converter terminal, provides a
fl exible interface system that
allows testing equipment to be
connected quickly. The LXXX
15.00, our high-performance
PCB terminal, is designed to
ensure long turbine service life.
The top box, which houses
the plant control system, con-
stitutes the electrical “core”
of the nacelle. Important infor-
mation is gathered here and
subsequently processed to
facilitate optimum plant ope-
ration. Safety and reliability are
vital for operation.
Our relays are vibration-proof,
switch reliably and are de-
signed to withstand a wide
range of temperatures. Our
WeiCoS tension clamp modular
terminals are universally appli-
cable for voltages up to 690 V
and facilitate quick installation,
thanks to their excellent plug-in
features. The plug-in surge pro-
tection module VARITECTOR
SPC is an excellent solution for
protecting signals, as it identi-
 es and reports errors and can
also be tested in accordance
with currently applicable
industry standards.
Electromechanical or hydraulic
brake systems and locking
systems that use bolts are
safety-related system compo-
nents. Trouble-free operation
in accordance with the relevant
guidelines and speci cations
is essential for protecting
investments and ensuring the
safety of the service staff
during maintenance.
Our sensor-actuator interface
modules and the relevant lines
ensure the reliable transmis-
sion of signals to the system
control. By virtue of features
such as resistance to sea water
and high protection classes
(IP 67/68), our modules ful l
the highest safety require-
ments. Our WAVE TTA mea-
suring signal converter is
ideally suited for detecting
speeds above and below set
thresholds.
In addition to power and signal
cables, it is also necessary
to install lighting and power
sockets in the tower. When it
comes to saving time and costs,
high-speed, easy-to-operate
system solutions are critical
success factors.
Weidmüller’s FieldPower
®
Box
reduces the time required for
installing electrical components
in the tower, thanks to the
establishment of high-speed
contacts between the tower
segments and the lighting
systems or power sockets.
With its practical FieldPower
®
LED solution, Weidmüller
brings light to the darkness.
The high level of fl exibility, ro-
bust design and easy handling
are features that allow reliable
individual connections and
simultaneously reduce installa-
tion costs.
Whether or not a gearbox is
used to generate power is a
question concerning the over-
all design of wind turbines that
varies from manufacturer to
manufacturer. When selecting
components for turbines with
gearboxes, potential contami-
nation from lubricants must be
taken into consideration.
Thanks to the particularly
compact design of our com-
ponents, such as the MCZ PT
100 measuring transducer,
which is housed in a 6-mm
terminal block and used for
temperature measurements,
we are able to reduce your
space requirements. It goes
without saying that it is also
equipped with tension clamp
connectivity. Our sensor-actua-
tor lines also have a proven oil
resistance for these types of
applications.
