Abstract
1,120,088. Control of A.C. motors; A.C. generators. MOSKOVSKY ORDENA LENINA ENERGETICHESKY INSTITUT. 22 Dec., 1966, No. 57365/66. Headings H2A and H2J. A synchronous generator 5 supplying A.C. traction motors 6 is driven by a gas turbine 4 forming part of a set which comprises compressor 2 which is driven at a selected speed by turbine 3. A field winding 7 of the generator is supplied through rectifier 8 from magnetic amplifier 9 having control windings 14, 15, opposed by control winding 16. The winding 14 is energized through choke 17 and rectifier 18 in accordance with the output voltage of the generator 5, the winding 15 being supplied from a unit 19 which compares the generator voltage with a reference signal derived from the set 1. The winding 16 also receives this signal. Braking resistors 22 are connectable to the traction motors through contactors 21. Over a lower range of frequencies, the winding 14 is effective so that the output voltage of the generator 5 is substantially proportional to the frequency. Over a higher range, the generator voltage applied to the comparator 19 overcomes a bias or Zener diode voltage, whereby winding 15 is energized to reduce the rate of increase of voltage with regard to frequency. Over a still higher range, the winding 14 is energized from a supplementary circuit comprising a resistor and a rectifier in series with rectifiers 18 to provide a constant voltage output. The winding 16 may be supplied through a tuned circuit from an A.C. tachometer generator through a diode and a potentiometer which is connected to a source of constant voltage. Alternatively, the control winding 16 is energized in accordance with the output of a transducer for converting movement of a fuel supply mechanism into an electrical signal. In another arrangement, the winding 7 is supplied from an exciter whose field winding is connected to the output of rectifier 8. The latter may comprise a diode bridge or thyristors. The magnetic amplifier 9 can be provided with stabilizing windings receiving signals from the field winding 7 through a capacitor or transformer.
