29-59 DETERMINAREA OPTIMALĂ A PARAMETRILOR GENERATORULUI ELECTRIC ASINCRON CU DOUĂ ÎNFĂŞURĂRI STATORICE – MODELUL MATEMATIC

PARAMETER OPTIMAL IDENTIFICATION OF DUAL THREE
PHASES STATOR WINDING INDUCTION MACHINE –
MATHEMATICAL MODEL
The parameter identification of a dual three phase’s stator winding
induction machine is approached in this paper by the genetic optimal algorithm.
The estimated parameter are: the voltage ratio between main and auxiliary
winding, the main winding resistance and leakage reactance, the cage rotor
resistance and reactance, the coupling leakage reactance between main and
auxiliary winding, the magnetization non saturated reactance, equivalent iron
loss resistance and mechanical losses including their variation with speed.
Keywords: asynchronous generator, two stator windings, equivalent
scheme parameters, calculating the optimal genetic algorithm
