Resumen:

The calculation of non-saturated inductances for a solid-rotor generator is performed using analytical formulae and finite-element computation. The inductance profiles are obtained in the ABC frame of reference. It is assumed that the machine is operating in the linear region of the open-circuit characteristic. Finite-element simulations are more accurate than analytical approaches since the electromagnetic phenomena is better represented. On the other, hand, analytical formulae is computationally less expensive but accuracy is questionable since many approximations are considered for their final establishment. Proper combination of both techniques gives a good trade-off between accuracy and computational casts. Steady-state inductances are employed for example in the determination of the machine operation safe regions. ©2007 IEEE.
