Stabilization of the electric power parameters of an autonomous generator based on a double-feed machine

摘要

The selection of electric power sources to operated under conditions of vary- ing rotational speed of actuating motors or turbines is considered. One solu- tion of the problem is to use a double-feed induction machine with variable amplitude, frequency and phase, with the incorporation into its rotor circuit of an additional e.m.f. from a static frequency converter.
