Resum:
In this doctoral thesis a technique has been designed for the constant parameters estimation for the single- and double-cage models, without air gap losses, of the three-phase induction machine; this technique is called Torque- Speed-Tracking, and obtains a path of theoretical behaviour from the manufacturer's data. Also, a technique for the estimation of four variable parameters for the single-cage model has been designed, whose resulting behaviour is compared with the obtained one with the double-cage model with constant parameters; in this technique each parameter is modelled with a polynomial function with constant coefficients, from experimental measurements. Finally, the obtained constant parameters are used to analysing the effects of voltage dips/sags using the listed models. The voltage dips/sags are classified in terms of their severity on peaks of: intensity, torque and slip, on a three-phase induction machine.
