This study presents a sensorless control of wind-driven doubly fed induction generators (DFIG) connected to an isolated load. The direct voltage control is adopted to command the rotor side converter. A Model Reference Adaptive System (MRAS) based technique is used in this topology for the sensorless generator speed estimation. The proposed sensorless control system is robust against speed and load...
A power generation system has been formulated based on a doubly fed induction generator (DFIG) supplying isolated loads. The stator is connected to the isolated load. Only one bidirectional converter with a battery is employed on the rotor side. The direct voltage control (DVC) is applied to control the DFIG system. To regulate the voltage and frequency load, the error of the measured rotor current...
