The Control Algorithm of AC Excited Grid Frequency Induction Machine Drive System and Its Main Circuitry Designing Research

There is very few suitable high performance-price ratio high-capacity middle-voltage drives which can be applied in rolling mills, fans and pumps in China. This paper presents the AC excited grid frequency induction machine(AEGFIM) drive system which is one of the ideal solutions of the middle-voltage frequency-variable drives. The key structure of AEGFIM is firstly introduced, then the current control algorithm and vector control algorithm is analyzed respectively. Finally the research of the mathematical model, designing method and current, voltage response is done. The AEGFIM drives which is firstly developed in China makes a contribution to the wide application to some extent in varied speed constant frequency generator in the future.
