The invention achieves stable voltage control which prevents harmful oscillations and is applicable in particular to asynchronous generators which are driven by a natural fluid.

摘要： Vibrations at harmonic frequencies are reduced by injecting harmonic balancing signals into the armature of a linear motor/alternator coupled to a Stirling machine. The vibrations are sensed to provide a signal representing the mechanical vibrations. A harmonic balancing signal is generated for selected harmonics of the operating frequency by processing the sensed vibration signal with adaptive filter algorithms of adaptive filters for each harmonic. Reference inputs for each harmonic are applied to the adaptive filter algorithms at the frequency of the selected harmonic. The harmonic balancing signals for all of the harmonics are summed with a principal control signal. The harmonic balancing signals modify the principal electrical drive voltage and drive the motor/alternator with a drive voltage component in opposition to the vibration at each harmonic.

摘要： A controller (28) for a doubly fed induction generator (12,20) adjusts control signals to a rotor side converter (24) and line side converter (22) to adjust rotor current when a voltage transient on a utility grid (10) occurs, so that the doubly fed induction generator can ride through the transient. The controller can also turn off the transistors of the rotor side converter (24) to reduce rotor current and/or activate a crowbar (42) to reduce the voltage of the DC link (26) connecting the converters (22, 24) when significant voltage transients occur on the grid (10). This permits continued operation of the DFIG system without disconnecting from the grid.

摘要： A hybrid voltage regulator controls the voltage of three phases of alternating electricity produced by an alternator. A digital voltage regulator produces an average of the RMS voltage for each phase and produces an error value based on a ratio of the voltage to the frequency of the alternating electricity. The RMS voltage average and the error value are used to modify a voltage command designating a desired voltage level. The modified voltage command is processed by an analog voltage regulator that rectifies the alternator output voltage which then is averaged over an period of time. The resultant average voltage value is utilized to modify the voltage command to produce a regulated voltage command that determines a level of current to apply to excite the alternator.

摘要： A starter-generator system supplies a controllable torque to a gas turbine engine, to thereby assist in starting the gas turbine engine, by independently controlling excitation frequency and/or voltage magnitude. The starter-generator includes a multi-phase exciter stator, a rotationally mounted multi-phase exciter rotor, a multi-phase main stator, a rotationally mounted multi-phase main rotor, and an exciter controller. The rotationally mounted multi-phase exciter rotor has a plurality of exciter rotor windings wound thereon that, upon excitation thereof with a rotating electromagnetic exciter flux generated by the exciter stator, have non-rectified excitation currents induced therein. The rotationally mounted multi-phase main rotor has a plurality of main rotor windings wound thereon that are electrically connected to receive the non-rectified excitation currents induced in the exciter rotor windings and that, upon excitation thereof with a rotating electromagnetic flux and in response to the non-rectified excitation currents supplied thereto, have currents induced therein that generate a main rotor torque to thereby cause the multi-phase main rotor and the multi-phase exciter rotor to rotate. The exciter controller is electrically coupled to at least the exciter stator and is configured to selectively supply the electrical excitation thereto, to thereby selectively control the generated main rotor torque.
