Turbine controller, AWC 500
Designed to last for more than 20 years
Designed to solve all challenges regarding turbine control,
DEIF’s Advanced Wind Turbine Controller, AWC 500, can be
installed in on- and o󰀨shore turbines ranging from small kW
up to the biggest 6-8 MW turbines.
Robustness
The AWC 500 is second-to-none the most robust controller
fully operational in extreme temperatures from -40 °C to +70
°C and at altitudes of 4,000 metres. Is immune to electrical
noise and designed specically with robustness in mind, the
AWC 500 is extremely protective against destroying surge
pulses and conforms to CE acceptance tests.
Pitch and turbine control
Applied as both turbine main controller and pitch controller,
especially in the Chinese market, DEIF’s AWC 500 has
been installed in more than 4,000 turbines. Characterised
by extremely cold winters and very hot summers, China is
perfectly illustrates why controller robustness is crucial.
High-level PLC programming or C/C++
Challenged by premature breakdowns, traditional automation
PLCs used as wind turbine controllers result in added spare
part and repair costs and, not least, lost production during
repairs.
PLCs designed for factory automation were simply not
designed for the tough conditions in wind turbines.
DEIF’s controller platform conforms to IEC 61131-3
programming with the widely used CODESYS V3 for high-
level programming or as embedded controller in C/C++ with
full power from our real-time Linux operating system. Via our
PLC Link, we deliver support for automatic code generation
from MathWorks MATLAB/Simulink & Stateow.
Park control and SCADA
DEIF applies the AWC 500 unconditionally as the most
preferred controller platform for complete control solutions.
Delivered as a standard solution for park control, the AWC
500 integrates the complete Park Control algorithm and also
serves as a platform for data collection and storage to control
large scale wind parks with reliable data gateways.
Controller retrot
The AWC 500 is a perfect t for the challenging conditions
o󰀨ered in older turbines due to their less advanced protection
and climate-controlled control cabinets. We can deliver
complete retrot solutions including control strategy, software
and component package, or open controller solutions.
DEIF collaborates with an open partnership approach and
can also provide technology transfer for software.

Integrated grid measurement
The accuracy of the control algorithms relies on a class
0.5 power measurement which denes a new standard in
the wind turbine controller industry. Up until now, the norm
has been class 0.5 voltage and current measurements
(multiplying to a lower accuracy of the power measurement).
Support for fast and precise LVRT reaction:
► Direct 690 V voltage, 1/5 A current and power
measurement (Class 0.5)
► No delay reading external transducer
► Calculates Energy (E), Power (P), Reactive Power (Q),
Phase angles etc.
► All values are directly available on GPM module for use

Unsurpassed durability
The AWC 500 is designed for high durability and veried
by HALT (Highly Accelerated Life Test) testing. Built to last
for more than 20 years, the controller has been constructed
using a selection of highly durable components with a long
supply life time. We provide a 5 year warranty on the AWC
500 controller - the longest in the wind industry.
Hot and cold climate
Handling cold starts from a guaranteed -40ºC, the AWC 500
secures a safe and controlled turbine start-up in very low
temperature environments.
The highest operating temperature for the AWC 500 is 70 ºC.
This is an advantage to the controller life-time. For every 10
degree the temperature is higher, the life-time is extended - a
general rule of thumb.
Surge power on the AWC 500 is DM 2 kV, CM 4 kV. Twice
the industrial standards on both power supply and I/O
terminals. These high standards improve robustness of the
controller enabling it to toleratefor instance lightning strikes
on the turbine.
All PCB modules are coated with an eco-friendly protective
layer.
High altitude installations
The controller is designed for full operation on all I/Os and
communication interfaces without requiring additional cooling
in high altitude installations up to 4,000 m.
Tolerance to voltage dips
If the power supply suddenly drops, the complete AWC 500
system including all I/O modules within the AWC 500 rack(s)
will continue to operate for a minimum of 50 milliseconds up
to 1 second.
If power supply returns within this period, the AWC 500
system will continue uninterrupted operation. If power is still
absent after the power-loss protection period, the AWC 500
will enter its safe shutdown cycle in which it will prioritize
as clean shutdown amongst writing data to FRAM and
dedicated areas of the le system cache to the internal ash.
This ensures that all data from the application is sent to the
power-loss protected data storage and will be available to
the application, when power supply returns.
Watchdogs on 4 di󰀨erent hardware and software
levels
To monitor the operation of the AWC 500 system, watchdogs
on di󰀨erent levels are featured, from each individual module
EtherCAT slaves, EtherCAT master, Operating system
services running to application watchdog.

System software
Robust data storage
Proven fail-safe le system (UBIFS – Unsorted Image File
System) to ensure data on the AWC 500:
► Tolerates sudden power interrupts and unclean reboots
► Recoverability – May be fully recovered if the indexing
information gets corrupted.
► Ensures data integrity – Everything written to the ash
media gets checksums.
Instant and long life storage of persistent variables is ensured
with FRAM (ferro magnetic RAM) as NOVRAM :
► High Endurance type guaranteeing 100 trillion read/
writes cycles
► 10 years storage without battery power necessary
Our new PCM5.2 relies on the ext4 le system and features
a lesystem cache that is written periodically every few
seconds, and a dedicated data area of persistent variables
is guaranteed to be persisted automatically to the mass
storage on power loss.
