DEIF’s control strategy technology for wind turbine control
With more than 20 years of know-how in wind turbine control systems for kW and MW turbines, DEIF’s control strategy is up to date with features like guided controller configuration at start-up, light-weight TCP/IP based remote HMI, service friendly parameter handling etc. making wind turbine commissioning, operation and service easier. DEIF’s wind turbine controllers are supplied with the customized wind turbine control strategy pre-installed and ready for installation.
The wind turbine technologies covered by the our main control systems and control strategy include:
- Fixed speed generators with traditional stall-regulated blades
- Variable speed DFIG (Double Fed Induction Generator)
- Full converted variable speed induction generator
- DD PMG (Direct drive and geared permanent magnet generator)
- Electric and hydraulic pitch positioning
All the applied systems are developed in close cooperation with our customers and include the latest technology to achieve efficient power and speed control, thus minimizing structural loads and optimizing the energy production over the turbine lifetime.
Small unique features add-ons
With 150 years accumulated wind turbine know-how in DEIF Wind Power Technology, our engineers have all been on-site, many small unique features are collected in our Control Strategy that . Examples are our handling of parameters with build-in validation, description of the parameters, backup and restore, and change logging. The light weight, TCP/IP based, multi-language, multi accessible operator interface (DEIF HMI) for local and remote operation - in a manner not seen on standard PLC-based systems. The DEIF HMI safely states who has the exclusive operator right for the wind turbine, improving the safety for the service people. Or simply when new wind turbines are installed, a wizard guides the operator safely through the controller configuration right from the first seconds after power on.
