Identification of wind turbine model for individual pitch controller design

Abstract

The use of wind power has been increasing rapidly over last few decades and according to all predictions this trend is likely to continue. At the same time need for better cost effectiveness of wind power plants has stimulated growth in wind turbinespsila size and rated power. As wind turbines grow in size they are subject to extreme structural loads and fatigue. In order to reduce such loads advanced control methods are explored among which individual pitch control has demonstrated very promising results. To design an individual pitch controller suitable wind turbine model is required. Derivation of wind turbine model for individual pitch controller design is addressed in this paper.
