A New Structure of Reciprocal Power-Fed AC Drive Test Platform Using DFIG

This paper constructs a reciprocal power-fed AC drive test platform (RDTP) using a doubly fed induction generator (DFIG) and proposes a voltage-source-mode control (VSMC) method for DFIG in this system. The proposed platform is suitable for the performance validation of various mechanical devices and induction motors. Compared with traditional RDTP, the nominal capacity and voltage of the inverter in this platform are significantly reduced. Therefore, the proposed structure has more cost-efficiency.
