Calculation on the digital computer symmetrical steady-state operation modes of asynchronous electric drives with additional non-linear resistances.

Abstract

Analytical expressions are proposed for the differential parameters of a saturated asynchronous motor, approximated by the meptod of harmonic linearization of nonlinear elements. It is shown that the use of these parameters makes it possible to significantly reduce the algorithm and the program for calculating the operating modes of an asynchronous electric drive with nonlinear resistances when solving the problem using the Newton iterative method.
