    摘要: The variable-speed accelerator includes an electric device, a transmission device, and a power supply portion that supplies electric power of a constant rated frequency supplied from a power supply to the electric device when the electric device is started. The electric device includes a constant-speed electric motor that rotates a constant-speed input shaft of the transmission device, and a variable-speed electric motor that functions as a generator in a generator mode and also functions as an electric motor in an electric motor mode. When starting the electric device, the power supply portion supplies the electric power generated by the variable-speed electric motor in the generator mode to the constant-speed electric motor after supplying starting power to the constant-speed electric motor and the variable-speed electric motor.

    摘要: A system includes one or more synchronous generators and one or more corresponding exciters. The exciter is configured to output a field current for exciting the synchronous generator to produce a voltage and a current at an output of the synchronous generator. The system may also include one or more electric motors electrically coupled to the synchronous generator and configured to drive one or more mechanical loads. A controller included in the system is configured to identify power angle oscillations between the voltage and the current and control an exciter voltage of the exciter to damp the identified power angle oscillations.

    摘要: A system includes one or more synchronous generators mechanically coupled to an excitation system. The excitation system is configured to output an excitation signal to excite the synchronous generator to produce a voltage and a current at an output of the synchronous generator. During startup of the synchronous generator, the excitation system may also output pulses of the excitation signal to initiate synchronism of one or more non-rotating electric motors electrically coupled to the synchronous generator. In addition, the pulses may be output to urge rotation of the non-rotating electric motors into rotational electrical alignment with the synchronous generator and each other.
