摘要： The disclosed technology is a cryogenic static exciter. The cryogenic static exciter is connected to a synchronous electric machine that has a field winding. The synchronous electric machine is cooled via a refrigerator or cryogen like liquid nitrogen. The static exciter is in communication with the field winding and is operating at ambient temperature. The static exciter receives cooling from a refrigerator or cryogen source, which may also service the synchronous machine, to selected areas of the static exciter and the cooling selectively reduces the operating temperature of the selected areas of the static exciter.

摘要： A power generation control apparatus of a rotating electrical machine for a vehicle is obtained which achieves load response control in a plurality of electric power generation control modes even if a generation voltage final target value rapidly changes. The apparatus includes a power control unit 103 and a storage battery 104 connected to a rotating electrical machine 102, and a rotation speed detection part 105 for detecting a rotational speed Na. The power control unit 103 controls power generation in a first mode when the rotational speed Na during operating as a generator is less than or equal to a predetermined value, and controls power generation in a second mode when the rotational speed Na is higher than the predetermined value. The power control unit 103 includes a generation voltage command value calculation section 111 that sets generation voltage command values Vr1, Vr2 for the individual modes, respectively, so as to follow a final target value to the storage battery 104, and a generation voltage update calculation command section 110 that instructs update timing tn, an amount of increase dH and an amount of decrease dL of each generation voltage command value to the generation voltage command value calculation section 111 based on the states of the rotating electrical machine and of the storage battery.

摘要： A generator control unit (GCU) provides active damping of a synchronous generator by monitoring the speed of the synchronous generator and detecting oscillations in the monitored speed. The oscillations are indicative of torsional oscillations within the mechanical drivetrain including the synchronous generator or generators. In response to detected oscillations in the monitored speed, the GCU generates a varying set-point value that is used to control the excitation voltage provided to the synchronous generator. Varying the excitation voltage provided to the synchronous generator causes a variation in synchronous generator torque. By selectively varying the torque in the synchronous generator, the GCU provides active damping in the synchronous generator that decreases or dampens the torsional oscillations.

The method includes deriving a plurality of generator safe operating boundary data expressions from power system data and/or user-defined inputs. The power system data may include a plurality of generator data supplied by a manufacturer of the generator and/or power system parameters such as power system equivalent impedance.
