Finally, comparisons between the estimated and experimental values of steady-state speed using proposed sensorless scheme with the machine working on the optimal power curve is shown in Fig. 3.15. From this figure, it can be noted that the estimated values of the DFIG speed and measured one have slight deviation in low values of wind speed. The discrepancy between the estimated and experimental speed values, especially at high values of wind speed, is attributed due to the mechanical loss which is disregarded in the machine model.
