Abstract
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.

A method for regulating the fuel injection in an engine of an electric generating set comprising an alternator driven by the engine, the alternator comprising a voltage regulator, the engine comprising a speed regulator having an input able to receive an external speed setpoint, the method comprising the following steps:
- detecting a variation of torque and of kinetic energy by electrical measurements on the alternator
- exerting, as a function of the amplitude of the torque variation relative to the kinetic energy level, an action on the input of the setpoint of the voltage regulator and/or of the speed regulator.
The method as claimed in the preceding claim, the modification of the current in the pole wheel being performed by decreasing the excitation current of the exciter.
A system for regulating the fuel injection in an engine of an electric generating set comprising an alternator driven by the engine, the alternator comprising a rotor having a pole wheel and a voltage regulator, the engine comprising a speed regulator having an input able to receive an external speed setpoint and a speed sensor, the system being configured to detect a variation of torque and of kinetic energy by electrical measurements on the alternator and exert, as a function of the amplitude of the torque variation relative to the kinetic energy level, an action on the input of the setpoint of the voltage regulator and/or of the speed regulator aimed at decreasing the torque demanded to the engine and/or at increasing the speed of the latter.
The system as claimed in the preceding claim, comprising a controller rotating with the rotor and making it possible to control the current in the pole wheel by a pulse width modulation of the voltage across the terminals of the pole wheel.
