FIELD: electricity.SUBSTANCE: invention in the field of electrical engineering. The system contains a synchronous generator with excitation from permanent magnets and three galvanically isolated three-phase windings at the stator, a static converter of electric energy based on direct frequency converter with three-phase output and natural commutation (a cycloconverter), which each phase is assembled as per the scheme of three-phase bridging reverse rectifier (BRR) with a capacitor of a low-frequency filter coupled in parallel to its output terminals and powered by one of the three-phase systems of the synchronous generator windings, one of the BRR outputs is coupled to the respective phase of a three-phase load. There is an additional phase of the direct frequency converter with three-phase output and natural commutation, which is assembled as per the scheme of three-phase bridging reverse rectifier with a capacitor of a low-frequency filter and powered from a three-phase transformer, which primary windings are coupled to any three-phase system of the synchronous generator windings, the second outputs of the three BRRs are coupled to one output of the additional phase of the direct frequency converter while the second output of the additional phase of the direct frequency converter is coupled to the zero wire of loads in the generating system.EFFECT: reduction of synchronous generator weight due to increase in input power factor of the electric energy static converter.4 dwg |
