FIELD: electricity.
SUBSTANCE: failure of one of electric actuators (1) and emergency shutdown of its frequency converter (4) is fixed, electric motor (7) of failed electric actuator is switched to electric power supply network through bypass switch (16), power is supplied to standby frequency converter (22) that is in cold standby, by switching switches (16) and (19) the electric motor (7) is switched to standby frequency converter (22), switched electric motor (7) is performed by standby frequency converter (22), and after operability of disconnected frequency converter (4) is restored, initial scheme of failed electric actuator (1) is restored and electric motor (7) is picked up by restored frequency converter (4).
EFFECT: reduction of relative power of standby converters, which is required for uninterrupted operation of circulating pumps of power facility.
