Parameter adjusting in voltage model actual values - determining amount of magnetising and torque generating components for rated operation

摘要

The parameters are formed by the stator resistance, inductance and stray inductance in the formation of rotor flux oriented orhogonal voltage actual values. The model is used for the control of a current rectifier fed async. machine, for which the rated voltage, current between its two angles, the ratio of the tilting moment to the rated moment, and the rated value of the circuit frequency of the stator voltage are given. The magnetising component and the torque component of the rated current at rated operation are determined according to specified formulae. The angle between rated voltage indicator and the rotor flux axis is formed at a sum of the two current angles. ADVANTAGE - Universal applicability, with single equalisation for parameter formation.
