Basics of the Wind Turbine Control Systems

Abstract

Taking into account the ideas presented in the previous chapters, one can highlight the objectives of the WECS control (see Section 2.7). The list bellow selects the most important:

• controlling the wind captured power for speeds larger than the rated

• maximising the wind harvested power in partial load zone as long as constraints on speed and captured power are met

• alleviating the variable loads, in order to guarantee a certain level of resilience of the mechanical parts

• meeting strict power quality standards (power factor, harmonics, flicker, etc)

• transferring the electrical power to the grid at an imposed level, for wide range of wind velocities
