Abstract :
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 and reference value feed the hysteresis regulator, the output of which are the control pulses. The reference rotor currents are obtained by the DVC technique. Simulation results for a 3.7 kW prototype DFIG are presented in this paper.
