The algorithms for calculating steady-state modes, static characteristics, and transients in an asynchronous drive based on a wound-rotor induction motor and a starter in a rotor circuit are presented. The calculation is based on a mathematical model of an induction motor that takes into account the saturation of the magnetic circuit. The electromagnetic processes are described by a nonlinear system of equations of electrical equilibrium composed in a fixed three-phase coordinate system, the coefficients of which are the differential inductances of the circuits. The steadystate modes and static characteristics are calculated by solving the boundary value problem using the continuation method in the parameter.

Przedstawiono algorytmy obliczania trybów pracy w stanie ustalonym, charakterystyk statycznych i stanów nieustalonych w napędzie opartym na silniku indukcyjnym z wirnikiem fazowym i rozrusznikiem obwodu wirnikowego. Obliczenia oparte są na modelu matematycznym silnika indukcyjnego uwzględniającym nasycenie obwodu magnetycznego. Procesy elektromagnetyczne opisane są nieliniowym układem równań równowagi elektrycznej w ustalonym trójfazowym układzie współrzędnych, z indukcyjnościami różnicowymi obwodów jako współczynnikami. Tryby pracy w stanie ustalonym i charakterystyki statyczne oblicza się rozwiązując problem wartości granicznych metodą kontynuacji w parametrze.
