The invention concerns a method for regulating the injection of fuel into a heat engine of a generator set including an alternator driven by the heat engine, the alternator including a voltage regulator, the heat engine including a speed regulator having an inlet that can receive an external speed setpoint, the method including the following steps: detecting a variation in torque and kinetic energy from electrical measurements on the alternator, carrying out an action on the input of the setpoint of the voltage regulator and/or the speed regulator, on the basis of the magnitude of the variation in torque relative to the kinetic energy level.

Method for regulating a generator set

The invention relates to a method for regulating the output voltage of the alternator of a generator set, said generator set including a heat engine driving the alternator, the alternator including a rotor having a pole wheel. Said method includes the following step: detection of an increase in the power at the outlet of the alternator, and in the event of a detected increase, the value of the current in the polar wheel is modified in such a way as to temporarily bring the output voltage of the alternator to a value lower than the value before the detection of the increase in power, with the aim of decreasing the level of torque required from the heat engine.

A method for regulating the output voltage of the alternator of a generator set, the generator set including a heat engine driving the alternator and the alternator including a rotor having a pole wheel. The method includes the following step: modifying the current in the pole wheel, at least during an increase in the load at the outlet of the alternator, in such a way as to bring the output voltage of the alternator to a value lower than the value before the increase in the load, the modification of the current in the pole wheel depending on the deceleration of the heat engine.
