DEIF Advanced Wind Turbine controller, AWc series

Engineered-to-application

The AWC series of controllers forms the hardware platform for pitch and main control

solutions engineered to your application. Being engineered to your specific type of wind

turbine, the AWC series is your guarantee of an optimised solution. DEIF possesses decades

of accumulated know-how about the entire wind turbine and its control systems – this know

how is all utilised to customise the solutions to a perfect fit.

The AWC series offers distributed solutions providing maximum reliability at minimum cost.

Placed near sensors and transmitters, an AWC reduces cabling, the risk of errors as well as

the need for man hours during installation.

Open software development with linux, c/c++, Iec61131-3 and MATlAB/Simulink

The AWC solutions are both ANSI C/C++ and IEC 61131-3 programmable and therefore very

flexible. This means that you are free to either carry out programming and later optimisation

on your own or leave it to us.

For C/C++ programming DEIF has tailored an Eclipse based development package and

compiler toolchain providing ‘one click’ from project to running programme on the controller.

You can choose to build your application based on DEIF’s proven wind turbine application

software, handling control and monitoring of main turbine components such as safety

system, grid connection, electrical or hydraulic pitch system etc. The development package is

compliant with Garrad Hassan’s control strategy.

IEC61131-3 programming in Structured Text, function block diagram, etc., is supported on

the AWC series controllers with the well-known CoDeSys PLC programming environment.

DEIF integrates the entire HMI and PLC configuration in this open environment, making it

straightforward to build a wind turbine application on the AWC series controllers.

At DEIF Wind Power Technology, we use model-based design and simulation with MathWorks

MATLAB/Simulink as the foundation for developing and optimising our control strategy

algorithms, so that they perfectly match each individual wind turbine design. We use our in

house developed PLC Link software tool to translate a wind turbine control strategy design

into C code and IEC61131-3 code (Structured Text) ready for integration with the surrounding

wind turbine application software. The auto-generated code is flawless, eliminating the risk

of human errors. At the same time, it is extremely fast compared to human programming –

potentially cutting months off the duration of your project.

In the same workflow an additional toolchain generates a Garrad Hassan Bladed and

FLEX5 compliant controller .dll file for wind turbine load verification.

Thanks to the developer tools available choosing the AWC platform minimises the time span

from we agree on the specification to your solution is ready.

Flexible and reliable hardware

Based on a modular rack concept, the AWC series provides compact, flexible and service

friendly solutions – right from simple plug-and-play rack modules to cabling fitted with

pluggable connectors.

The AWC series is designed and constructed to meet the strict requirements for maritime use

which exceed industrial norms by far. The maritime norms prescribe increased performance

on several parameters such as EMC, vibration and shock resistance, temperature spanning,

etc. On some parameters, the AWC series even exceeds the requirements from classification

societies.

For instance, the AWC 500 operates from -40 to +70Cº and can be stored from -40 to

+85Cº. The durability of the hardware is verified by HALT testing (Highly Accelerated Life

Test) – the construction is designed for a lifetime of no less than 20 years. In other words, choosing

the AWC platform equals choosing a hassle-free solution with a minimum of downtime.
