Control Strategy For Five Phase Dual Stator Winding Induction Starter/generator Systems

Control Strategy For Five-Phase Dual-Stator Winding Induction Starter/ Generator System.

Abstract:

This paper presents an integrated control strategy for a starter/generator (S/G) system based on five-phase dual-stator winding induction machine (FPDWIM). The FPDWIM has a cage-type rotor and two sets of stator windings. One is a five-phase control winding (CW) and the other is a five-phase power winding (PW). In the starting mode, the FPDWIM works as a motor. The CW provides both active power and reactive power to drive the engine. In the generating mode, the CW mainly handles reactive power while the PW outputs active power. To achieve the integration of the starting and generating controls, indirect CW-flux-oriented control (ICWFOC) is proposed to operate in both starting and generating modes. In starting mode, the CW current and flux are controlled to output a constant starting torque; while in generating mode, both CW and PW DC bus voltages are regulated.
