Abstract :
The steady state performance of a stand-alone variable speed constant frequency generation system using slip ring induction motor and two back-to-back connected IGBT based PWM converters is investigated in this paper. A new algorithm is developed which builds the DC link voltage up from a low initial value to the desired level without undue stress either on the machine or on the power converters. In steady state, the dc link voltage, machine flux, output voltage and frequency are tightly regulated as the load and the machine speed are varied over wide (sub synchronous to almost twice the synchronous speed) range. The control algorithm was implemented on a TMS320C31 based DS1102 DSP board which generated the control voltages for the PWM modulators.
