Abstract
Desynchronization of a synchronous machine is predicted by detecting a phenomenon of radical variation of the magnetic flux in the gap of a synchronous machine immediately before falling into an asynchronous state. For example, each functional value of the direct axis flux and the quadrature axis flux in the gap is detected for comparing the variation of each functional value with a predetermined reference level to predict desynchronization of the synchronous machine.
