Set-up
The Nordex N100/3300 wind turbine is a speed-variable wind turbine with a rotor
diameter of 99.8 m and a nominal power of 3300 kW. This wind turbine is
designed for 50 Hz or 60 Hz. The wind turbine is designed for class 1a in
accordance with IEC 61400-1.
The wind turbine Nordex N100/3300 is made up of the following main
components:
● Rotor, consisting of rotor hub, three rotor blades and the pitch system
● Nacelle with drive train, generator and yaw system
● Tubular tower with foundation
● Medium-voltage transformer (MV transformer) and medium-voltage
switchgear (MV switchgear)
1.1
Tower
The Nordex N100/3300 is erected on tubular steel towers for different rotor hub
heights.
The tubular steel tower is a cylindrical tower. The top section is conical.
Depending on the hub height the tower is composed of three or five tower
sections.
Corrosion protection of the tubular steel tower is ensured by a tower surface
coating system according to ISO 12944.
A service lift, the vertical ladder with fall protection system as well as resting and
working platforms inside the tower allow for a weather-protected ascent to the
nacelle.
The foundation depends on the ground conditions at the intended site. An
anchor cage is imbedded in the foundation for anchoring the tower. Tower and
anchor cage are screwed together.
In the standard version, the tower base only accommodates the switch cabinet.
The switch cabinet contains important components of the electronic controls,
turbine PC, frequency converter, main switch, fuses and outputs to the
transformer and to the generator.
The frequency converter is equipped with a water cooling system. The water
heated in the frequency converter is cooled in a water/air heat exchanger. It is
located externally close to the tower door.
The MV transformer and MV switchgear are located in a separate transformer
substation near the wind turbine.

As an option, the MV transformer and MV switchgear can also be installed in the
tower base. In this case, the components are arranged in the tower base on
three different levels:
● The MV transformer on the foundation
● The MV switchgear on the 1st tower platform
● The switch cabinet with frequency converter on the 2nd tower platform
In the case of a separate transformer substation, the MV transformer is usually
designed as an oil transformer. If the transformer is installed inside the tower, a
dry-type transformer is used.

Rotor
The rotor consists of the rotor hub with three pitch bearings and three pitch
drives for blade adjustment as well as three rotor blades.
The rotor hub has a modular design. The base frame of the rotor hub is made
up of a stiff cast structure Onto this element, pitch bearing and rotor blade are
mounted. The rotor hub is covered with the spinner which enables the direct
access from the nacelle into the rotor hub.
The rotor blades are made of high-quality glass-reinforced plastics. Each rotor
blade is equipped with a highly effective lightning protection system.
In accordance with the guidelines IEC TS 61400-23 and GL IV-1 (2400) the rotor
blade is statically and dynamically tested with loads that were even beyond
standard design requirements.
The pitch system serves to adjust the pitch angle of the rotor blades set by the
control system. For each individual rotor blade, the pitch system comprises an
electromagnetic drive with 3-phase motor, planetary gear and drive pinion, as
well as a control unit with frequency converter and emergency power supply.
Power supply and signal transfer are realized through a slip ring assembly
located in the nacelle.
1.3
Nacelle
The nacelle contains essential mechanical and electronic components of the
wind turbine. The nacelle is mounted on the tower in rotating bearings.
The rotor shaft is mounted on the rotor bearing in the nacelle. In the rotor
bearing a mechanical rotor lock is integrated used to securely lock the rotor.
The gearbox increases the rotor speed until it reaches the speed required for
the generator.
The bearings and gearings are continuously lubricated with cooled oil. A 2-stage
pump enables the oil circulation. A combined filter element with integrated
coarse and fine filter removes solids. The control system monitors the level of
contamination of the filter elements (differential pressure measurement).
Optionally, an additional offline filtration can be installed (super fine-mesh filter
5 µm).
The gear oil used for lubrication also serves as a gearbox cooling. The
temperatures of the gearbox bearings and the oil are continually monitored.
When the optimum operating temperature is not reached yet, a thermal bypass
shorts the circuit and conducts the gear oil back to the gearbox. If the optimum
working temperature of the gear oil is exceeded it is cooled down.
The gearbox cooling is achieved with an oil/water cooler with stepped cooling
capacity. The cooler is installed directly at the gearbox. The heated cooling water
is recooled together with the cooling water of the generator in a passive cooler
on the roof of the nacelle.

The mechanical rotor brake supports the aerodynamic braking effect of the
rotor blades as soon as the speed falls below a defined value and finally stops
the rotor. The aerodynamic braking effect of the rotor is achieved by adjusting
the rotor blades perpendicular towards the rotation direction. The rotor brake
consists of a brake caliper which acts on the brake disk mounted behind the
gearbox.
The yaw drives optimally rotate the nacelle into the wind. The four yaw drives
are located on the machine frame in the nacelle. A yaw drive consists of an
electric motor, multi-stage planetary gear and drive pinion. The drive pinions
mesh with the external teeth of the yaw bearing.
If positioned properly the nacelle is locked by means of a electric brake system.
It consists of several brake calipers which are fastened to the machine frame and
act on a brake disk. In addition, the electric motors of the yaw drives are
equipped with an electrically actuated holding brake.

Functional principle
The turbine operates automatically. A programmable logic controller (PLC)
continuously monitors the operating parameters using various sensors,
compares the actual values with the corresponding setpoints and issues the
required control signals to the WT components. The operating parameters are
defined by Nordex and adapted to the individual site.
When there is no wind the WT remains in idle mode. Only various auxiliary
systems, such as heating and gear lubrication, and the PLC, which monitors the
data from the wind measuring system, are operational. All other systems are
switched off and do not use any power. The rotor idles.
When the cut-in wind speed is reached, the wind turbine changes to the mode
'Ready for operation'. Now all systems are tested, the nacelle aligns to the wind
and the rotor blades turn into the wind. When a certain speed is reached, the
generator is connected to the grid and the WT produces electricity.
At low wind speeds the WT operates in part-load operation. In the course of this
the rotor blades remain fully turned into the wind (pitch angle 0°). The power
produced by the WT depends on the wind speed.
When the nominal wind speed is reached, the WT switches over to the nominal
load range. If the wind speed continues to increase, the speed control changes
the rotor blade angle so that the rotor speed and thus the power output of the
WT remain constant.
The yaw system ensures that the nacelle is always optimally aligned to the wind.
To this end, two separate wind measuring systems located at the height of the
hub measure the wind direction. Only one wind measuring system is required for
control system, while the second monitors the first and takes over in case the
first system fails. If the measured wind direction varies too greatly from the
alignment of the nacelle, the nacelle is yawed into the wind.
The conversion of the wind energy absorbed from the rotor to electrical energy
is achieved using a double-fed asynchronous generator with slip ring rotor. Its
stator is directly and its rotor via a specially controlled frequency converter
connected to the MV transformer. This offers a significant advantage enabling
the generator to be operated in a defined speed range near its synchronous
speed.
If certain parameters concerning turbine safety are exceeded, the WT will cut out
immediately, e.g. if the cut-out wind speed is exceeded. Depending on the cause
of the cut-out, various braking programs are triggered. In the case of external
causes, such as excessive wind speeds or grid failure, the rotor is softly braked
by means of rotor blade adjustment.
