Conclusion
Design and prediction of the operation of synchronous machines by CAD

Finite element calculation methods are increasingly becoming an integral part of the tools used by the engineer responsible for dimensioning synchronous machines. The ever-increasing power of computer hardware means that these tools are constantly being improved. The main areas of development are as follows:

• taking into account variable rotor speed by introducing the mechanical equations of the shaft line ;

• study of the resynchronization of the alternator on the network after elimination of a fault ;

• modeling the frequency and power regulation of an alternator, and studying its stability on the network;

• calculation of induced currents and rotor pole surface losses ;

• step-by-step modeling of a rotating diode...
