Computer analysis of a dynamic system consisting of a load and two induction motors connected in parallel both electrically and mechanically

A computer analysis of a load system driven by two induction motors connected in parallel both electrically and mechanically is presented. The generalized equations in the d-q coordinate system of two three-phase induction motors have been produced from those of a single three-phase induction motor. The dynamic analysis of the system was done for the cases in which both equal and unequal motors have been used. Transient and steady-state responses were observed by solving system model equations. The solutions were obtained using the Runge-Kutta method, and the results were plotted for conclusions
