A demand for the highest possible power density in electrical machinery in some applications often requires a change in conventional and well-known three-phase stator winding solution. This paper discusses high-power turbogenerators with a six-phase winding. Mutual inductance between two three-phase windings requires updating of the equations for transient processes modelling. The equivalent circuits and equations for the dq0-reference frame are summarised, sudden six-phase and three-phase winding short circuit processes of the generator under load are modelled.
