摘要： A method for determining a droop response profile of a rotating electrical machine supplying electricity to an electrical network having a network frequency varying on either side of a nominal frequency, wherein a measured rotational speed value and droop response parameters are defined. The droop response profile is a graph centered on the coordinates ([X5; Y5]) of an origin point between 99% and 101% of the measured speed value and defined by at least two coordinate points ([X4,Y4], [X0, Y0]) in the case of over-speed, each of the points having as abscissa a speed value as a percentage of the measured speed value, and for ordinates a filtered speed value as a percentage of the measured speed value modulated by at least one of the droop response parameters.

摘要： A frequency of an AC voltage of an AC grid present at a genset is defined by an UPS. The frequency is altered in one direction away from a desired frequency, if a power demand increases beyond a power supply in the AC grid, and in the other direction, if the power demand falls below the power supply. An alteration of the frequency in the one direction is limited to a maximum value in that missing power is temporarily fed out of an energy storage of the UPS into the AC grid. A shift of the frequency in the one direction is kept until no more power flows out of the energy storage. The genset responds to deviations of the frequency of the AC voltage from the desired frequency in the one and the other direction by an increase and a decrease of supplied genset power, respectively.

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.
