Sustainable Control. a new approach to operate wind turbines. Final public report

This final report summarizes the work performed in the framework of the long-term EOS research project "Sustainable Control. A new approach to operate wind turbines", partially financed by the Dutch agency governmental AgentschapNL under number EOSLT02013. Within this project, a novel approach to operate wind turbines more...

Distributed Blade Control

Wind turbine designs are driven by aerodynamic loads on the structure. If loads are reduced, the dimensions of certain parts and the total cost can be reduced. Individual pitch control (IPC) is known to be effective, but a rotor with distributed blade control (DBC), also known as a smart rotor, can achieve more. With DBC the aerodynamic shape of...

Exploring the Limits in Individual Pitch Control

Individual pitch control (IPC) is an advanced wind turbine control method for fatigue load reduction. The conventional IPC algorithm (cyclic pitch control) aims at achieving 1p blade load reduction by mitigating the static rotor tilt and yaw moments. Besides these existing IPC methods, this paper presents a novel application of IPC: rotor...

Feedback-feedforward individual pitch control for wind turbine load reduction

This paper focuses on the problem of wind turbine fatigue load reduction by means of individual pitch control (IPC). The control approach has a two-degree-of-freedom structure, consisting of an optimal multivariable LQG controller and a feedforward disturbance rejection controller based on estimated wind speed signals. To make the control design...

Modern wind turbine controller design

The ECN Control Design Tool (CDT) is used to design wind turbine feedback control algorithms. Due to its automated code generation it combines high level development with seamless integration with aero-elastic codes and PLC hardware. TURBU greatly enhances the range of controllers that can be developed with the CDT (like individual pitch and...

Real-time processimulator voor windturbinebesturingen Modellering en implementatie. Algemeen eindrapport

The development of a real-time simulator for a complete wind turbine system has been carried out for the evaluation of the overall control system. The real-time simulator software has been developed in Matlab/Simulink and supports automated real-time compilation (Real Time Workshop) to a real-time code for use at a hardware platform (dSpace, xPC...

TURBU Offshore, Computer Program for Frequency Domain Analysis of Horizontal Axis Offshore Wind Turbines Implementation

<wegfont face="Times New Roman" size=3><p> The design of offshore wind turbines requires to assess a huge amount of different seastates and wind conditions. Therefor the calculational efficiency of a combined time/frequency domain approach is attractive. This was the reason for the development of the frequency domain...
