FIELD: electricity.

SUBSTANCE: present invention pertains to electrical engineering and can be used in parametric machines in the electrical energy industry as electric generators and electric motors, for example on electrical power stations. The synchronous generator-compensator is a combined electrical machine, the circuit of which has an electronic frequency converter, with power corresponding to an asynchronous motor. On one axle of the synchronous generator-compensator there are series-arranged rotors of the drive motor, synchronous generator with a thyristor-type self-triggering system, and the asynchronous motor with a short-circuited rotor. The rotor of the asynchronous motor is in form of a flywheel with a large diameter, radius R and mass, which matches up the radius r and mass of the rotor of the synchronous generator, respectively, calculated using the mechanical resonance formula. The ratio R/r is chosen in accordance with the Fibonacci number sequence. The output of the synchronous generator and the input of the stator of the asynchronous motor are connected through a frequency converter, supplying the asynchronous motor with current, with discrete synchronisation of the frequency of current from the synchronous generator and frequency of the angular impulse of the asynchronous motor. The circuit of the frequency converter has massive capacitors, with provision for mechanical positive feedback from the rotor of the asynchronous motor to the rotor of the synchronous generator due to the single axle of the rotor of the asynchronous motor and the synchronous generator. The rotor of the asynchronous motor has ratio of the width to its radius in accordance with the Fibonacci number sequence, in succession to the chosen ration R/r. The diameter of the asynchronous motor is increased, corresponding to the rotor, with provision for clearance between the stator and the rotor of 1-3 mm. The method of operation of the synchronous generator-compensator is implemented, as is described in the material of the claim.

EFFECT: increased fuel saving in the drive motor, due to increase in moment of inertia on the system axle.
