Dynamic properties of single supply back-to-back high power salient poles synchronous machine can be analyzed experimentally and by modelling and simulation. Simulations give useful information, theoretically and in practice, difficult or impossible to obtain another way. It is shown that it is possible to derive mathematical models that can take into account basic processes of the two machines and to offer results regarding electromagnetic and mechanical stresses, placed in a controlled area of practice. The research validates a method for testing at manufacturer of high power synchronous machines.
