FUNCTIONAL OUTPUT-CONTROLLABILITY ANALYSIS OF FIXED SPEED WIND TURBINE
M. Isabel Garcia-Planas, Jose Luis Dominguez-Garcia
This paper deals with the concepts of functional output-controllability character of a finite-dimensional linear dynamical system. After defining the approach used for computing the functional output-controllability consisting on the fact that relationship between a certain constant matrix rank and the system dynamics. The linear system under study is a fixed speed wind turbine (FSWT) formed by a squirrel cage generator connected directly to the grid. Due to the non-linear behaviour os such system, the linear system model is calculated by means of a Taylor's decomposition of the non-linear equations of the squirrel cage induction generator, being the system linearized around a steady state operating point. Finally, the study of the functional output-controllability of such system is done, and some boundaries are given to ensure functional output-controllability from some given operational values.
