UNINTERRUPTED AND GUARANTEED POWER SUPPLY SYSTEM FOR ELECTRIC POWER CONSUMERS Russian patent published in 2020 - IPC H02J9/04 

FIELD: electrical equipment.

SUBSTANCE: field of application: electrical equipment. According to the invention, the asynchronous generator has an autotransformer winding of the stator, which consists of eighteen coil groups connected in series to an external triangle, with first leads: (19), (20), (21) taken from the tops of the outer triangle, from the combined beginning of the first and the end of the fifteenth coil group, from the combined beginning of the seventh and the end of the seventeenth coil group, from the combined beginning of the thirteenth and the end of the fifth coil group, to the second coil outputs: (22), (23), (24) taken from the tops of the inner triangle, from the combined beginning of the tenth and the end of the twelfth coil group, from the combined beginning of the sixteenth and the end of the eighteenth coil group, from the combined beginning of the fourth and end of the sixth coil group, wherein end of first coil group is connected to tenth end, beginning of twelfth coil group is connected to end eighth, beginning of eighth coil group is connected to beginning of third coil, end of third coil group is connected to beginning of seventeenth, end of seventh coil group is connected to end of sixteenth, beginning of the eighteenth coil group is connected to the end of the fourteenth, the beginning of the fourteenth coil group is connected to the beginning of the ninth, the end of the ninth coil group is connected to the beginning of the fifth, the end of the thirteenth coil group is connected to the end of the fourth coil, beginning of the sixth coil group is connected to the second end, beginning of the second coil group is connected to the beginning of the eleventh, end of the eleventh coil group is connected to the beginning of the fifteenth, at that, the autotransformer winding of the stator has a coefficient of differential scattering equal to R_d = 0.0038, and by its first outputs through high-speed automatic circuit breaker is connected to supply network, with relay of control of active power direction, excitation capacitors and capacitors control reactive power, in zero point of which by their output is connected regulator-voltage stabilizer, and input with second outputs of stator winding, taken from vertices of internal triangle, to which output contacts for connection of load and input of frequency control and control device are also connected, and its output with base and emitter of control transistor, DC motor parallel motor, and its excitation winding through control transistor are connected to positive and negative outputs of storage battery, to which is parallel connected output of three-phase controlled rectifier with functions of charging device, input of which is connected to supply mains.

EFFECT: technical result is improvement of operating characteristics of asynchronous generator due to reduction of coefficient of differential dissipation of winding, higher quality of output voltage and providing switching of load in emergency modes without breaking of sinusoid of supply voltage.
