Изобретение относится к электротехнике и может быть использовано для регулирования частоты вращения двигателя двойного питания. Способ предполагает питание обмоток статора двигателя из трехфазной сети, а обмоток ротора - от преобразователя частоты. При достижении двигателем частоты вращения, превышающей частоту вращения поля статора, изменяют чередование фаз обмоток статора, одновременно изменяют напряжение, подведенное к обмоткам ротора. Угол открывания тиристоров инвертора преобразователя частоты поддерживают неизменным в процессе регулирования частоты вращения. Устройство, реализующее способ, содержит фазопереключающее устройство, согласующее чередование фаз в силовой цепи и в системе управления инвертором. Изобретение позволяет увеличить диапазон регулирования частоты вращения. 2 с.п. ф-лы, 3 ил.The invention relates to electrical engineering and can be used to control the rotational speed of a dual power engine. The method involves powering the motor stator windings from a three-phase network, and the rotor windings from the frequency converter. When the engine reaches a rotation frequency exceeding the rotation frequency of the stator field, the phase rotation of the stator windings changes, simultaneously changing the voltage applied to the rotor windings. The opening angle of the thyristors of the inverter frequency converter support unchanged in the process of regulating the rotational speed. A device that implements the method contains a phase-switching device, matching the alternation of phases in the power circuit and in the inverter control system. The invention allows to increase the range of speed control. 2 sec. f-ly, 3 ill.
