FIELD: electricity.
SUBSTANCE: system for generating electric enetrgy of three-phase alternating current comprises switching elements, a three-phase generator, including a rotor surrounded by a stator comprising three-phase windings, which are designed to provide, in conjunction with the corresponding switching elements, the modulation of the electric energy parameters of the three-phase alternating current, summing three-phase transformers for load connection. The initial terminals of the phase windings of the three-phase stator windings are connected to respective terminals A, B, C of the input three-phase windings of the summing three-phase transformers, and the other terminals of the phase windings of the three-phase stator windings are connected to the switching elements corresponding to the three-phase stator windings. The similarly-named phase windings of three-phase output windings of three-phase transformers are series-connected in three branches making a star-connected circuit and a three-phase output. In an embodiment, the stator has three equally executed parts, which are arranged in series along the rotor. Each of the parts includes two three-phase windings. In each of the stator parts, the initial terminals of the phase windings of one three-phase winding and the ends of the phase windings of the other three-phase winding are connected to the corresponding terminals A, B, C. Phase windings of three-phase windings of one of the stator parts are series-connected to the corresponding terminals A, B, C, and phase windings of the three-phase windings of the other two stator parts are series-connected to the corresponding terminals B, C, A and C, A, B. In another verison stator has two equally executed parts which are series-arranged along the rotor. Each part includes three three-phase windings. In one stator part, the initial terminals of the phase windings of one three-phase winding are series-connected to the corresponding terminals A, B and C, and the initial terminals of the phase windings of the other two three-phase windings are series-connected to the corresponding terminals B, C, A and C, A, B. In the other stator part, the ends of the phase windings of one three-phase winding are series-connected to the corresponding terminals A, B and C, and the ends of the phase windings of the other two three-phase windings are series-connected to the corresponding terminals B, C, A and C, A, B.
EFFECT: increased efficiency of the process of converting mechanical energy into electrical energy, expanded functionality and scope of use, as well as increased efficiency coefficient and reliability.
