成果简介	NOVELTY - Invention relates to balancing of currents and voltages in electric networks, outputting the entire power of the generator to a single-phase load, increasing the reliability of supplying the generator loads and is intended for balancing electric loads of generator in order to reduce losses of electric power in it and prevent reduction of its service life, as well as the possibility of outputting the entire power of the generator to a single-phase load and increasing the reliability of supplying the generator loads. In the proposed method, the three-phase alternating current and voltage generated by the generator are first converted into direct current and voltage using a three-phase rectifier, after which it is converted again into alternating current and voltage using, or three-phase inverter with output power, which is not less than generator power, for supply of three-phase, including asymmetrical load, or using a single-phase inverter with output power of at least three-phase power of the generator, for supplying a single-phase load with power comparable to the three-phase power of the generator. Phase currents and voltages of the generator are balanced by conversion into direct current and voltage using a three-phase rectifier and subsequent conversion into alternating current and voltage using a three-phase inverter. Operation of rectifier, three-phase and single-phase inverter is controlled. When supplying three-phase, including asymmetrical, three-phase inverter is switched on, and three-phase load, including asymmetric one, is supplied from it. In case of failure of rectifier or three-phase inverter they are automatically shunted by means of bypass switching device. When supplying a single-phase load with power comparable to the three-phase power of the generator, a single-phase inverter with output power comparable to the three-phase power of the generator is switched on, and a single-phase load with power comparable to the three-phase power of the generator is supplied from it. In case of failure of rectifier, three-phase or single-phase inverter, single-phase load is automatically disconnected by means of switching device. Inform about the rectifier or three-phase inverter failure, respectively, thus increasing reliability of loads supply due to prompt response and elimination of damage. USE - Electricity. ADVANTAGE - Reduction of losses in generator, prevention of reduction of generator service life, provision of possibility of output of all power to single-phase load with power comparable to power of generator, increase of load power supply reliability. 1 cl, 1 dwg
