Heat and Flux: Increase of Wind Farm Production by Reduction of the Axial Induction

At the windward side of a wind farm, the paper proposes to operate the wind turbines at an axial induction factor below the Lanchester-Betz optimum of 1/3. The paperÆs analysis shows that the power of the turbines under the lee will increase more than the decrease of the power of...

R&D Needs for O&M of Wind Turbines

Operation and Maintenance (O&M) of wind farms is usually an activity which is carried out by industrial parties only. This paper shows that in addition to the industrial developments, the results of R&D efforts lead to a more structured approach of the O&M issue and towards optimization of the maintenance...

Assessment and Optimization of Operation and Maintenance of Offshore Wind Turbines

This paper describes two models for modeling the O&M aspects of offshore wind farms. One has been developed by TU-Delft, and the other one by ECN Wind Energy. The features and benefits of both models are illustrated by means of a case study for the 500 MW DOWEC wind farm....

Electrical and Control Aspects of Offshore Wind Farms II (Erao II)

The focus of this paper is to investigate dynamic interaction of wind farms and the electrical grid; dynamic models of wind farms are needed. These models will be of great help in the evaluation of the behavior of wind power during normal grid operation as well as during grid faults...

More Power and Less Loads in Wind Farms: 'Heat and Flux'

The paper considers a farm as a single energy extracting body instead of a superposition of individual energy extractors i.e. winds turbines. As a result it found two new hypotheses called Heat and Flux. Both hypotheses reveal that the classical operation of turbines in a wind farm at the Lanchester-Betz...
