Asymmetrical model of DWIG for aircraft variable frequency AC generating system

This paper presents the mathematical model of dual-stator-winding induction generator (DWIG) for aircraft variable frequency ac generating system under asymmetric operation. Firstly, the asymmetric mathematical model of DWIG under the A-B-C three-phase static coordinate system is built. Then, for the asymmetric operation, the zero-axis component is considered, and the asymmetric mathematical model of the DWIG in the d-q-0 three-phase orthogonal rotating coordinate system is obtained. Based on this, the simulation of the DWIG and whole system is built in the MATLAB/ SIMULINK Simulation and experiments are carried out under single-phase full load, two-phase full load and three-phase asymmetric load. The results of simulation and experiment prove the correctness of the mathematical model.
