Abstract

Changes and pulsations in the active and reactive powers generated by wind turbines due to wind speed variations and tower shadow effect may cause serious problems in operation of isolated or distant areas of power grids. Particularly resulting flicker effect may deteriorate power quality in connected power networks. Use of doubly fed machines with suitable control method may substantially reduce impacts of these phenomena. Vector control of doubly fed machines is analyzed and discussed in the paper with respect to the compensation of varying mechanical torque produced by wind turbines. Properties of power units with induction generators and doubly fed machines are compared.
