Rotor power flow control of doubly fed induction generator using dspACE ds1104

Abstract

An RSC control of a DFIG connected to grid using controller objective dSPACE ds1104 is presented. A stator flux control vector scheme is exercised to control the both active & reactive powers produced at stator terminals by DFIG. Rotor excitation is given by using an appropriate SPWM pulse fed Inverter at rotor side achieved by changing modulation index & modulation frequency. For MI & MF SPWM pulses, dSPACE dS1104 is employed for real time control & generation. Updation of corresponding parameters in display are observed through Control Desk.
