Control strategy for five-phase dual stator-winding induction generator DC generating system

摘要

This paper presents a dc generating system based on the five-phase dual stator-winding induction generator (DWIG) with the static excitation controller (SEC), and also investigates its control strategy. In this five-phase DWIG, the cage-type rotor is employed and it has two sets of five-phase stator windings (power winding and control winding). Based on the instantaneous power theory, a control winding field oriented control (CWFOC) strategy considering third-harmonic injection is proposed. The simulation results support the proposed control strategy, the five-phase DWIG dc generating system can have a good performance.
