Speed Control of Wind Turbine through Pitch Control using Different Control Techniques

Pitch control is one of major aspect of wind turbines control particularly in high wind speed and wind oscillations. General Electric model of wind turbine is practically compatible with the structure of the wind turbines. Simulation results using this model are closer to the actual case, compared to that of the other models.
At this end, results of application of Fuzzy, self-organized Fuzzy and PI controllers as well as the case with no controller in pitch control process are compared. With connection to the electrical power limit and converter cost, economical analysis of pitch controller application is carried out. It is shown that application of a self-organized Fuzzy controller result is around $142,646 saving.
