Mathematical model of the two orthogonal three-phase windings stator generator

This paper considers the induction generator having two similar separate three-phase stator windings, wound for the same number of poles and a standard squirrel rotor (IG2). Here is given the mathematical model of such induction machine, which is based on our previous results, namely, the two separate stator windings must be space-displaced at 90 electrical degrees, one from the other (orthogonal displacement). The mathematical model was obtained taking into consideration the operation of the considered generator in the specific regimes of unconventional electrogenerator systems (microhydro, wind, thermal motor driven generator systems, etc.) and can be used for the analysis of such systems operation regimes.
