| Popis: |
The authors describe a unified loss model of a converter induction machine system such that steady state loss characteristics as well as the dynamic behavior of both machine and converter are accurately represented. The machine electrical losses. such as stator and rotor copper loss, core loss, and stray loss, are considered for both fundamental and harmonic frequencies. Also considered are the skin effect on rotor resistance, the temperature effect on both stator and rotor resistances, magnetizing inductance saturation, and friction and windage loss. All these features are incorporated in synchronously rotating frame dynamic D/sup e/-Q/sup e/ equivalent circuits. A converter system that includes a diode rectifier and pulse-width modulation transistor inverter has been modeled accurately for conduction and switching losses. The machine and converter drive system, and been simulated for a vector-controlled drive system, and validity in both steady state and transient condition has been verified. > |
