Abstract :
In this manuscript, we propose to compare two novel sensorless strategies control of doubly fed induction generator (DFIG) based on the output electrical power, and rotor and stator current with stator voltage measurement. The performances of the proposed sensorless strategies are compared. The developed control strategy was tested for different operating modes: real wind speed with balanced and unbalanced grid voltage, stepped wind speed with balanced and unbalanced grid voltage. The principle of the rotational speed estimation is described and implemented using Matlab/Simulink software. The simulation results demonstrate the feasibility of the control strategy based on the measurement of the output power.
