Abstract

The paper approaches the analysis of the performances of doubly-fed induction generators for grid-connected wind turbines by means of algebraic analytical relationships given by the mathematical model of the machine. These relationships are used to carry out a control strategy which aims to maximize the global efficiency of the generation system. Some considerations about the sizing of the rotor converter are also reported. The control strategy has been verified by means of numerical simulations.
