Embodiment Construction

[0055] as in figure 1 A generator set according to the prior art shown in , comprises an engine 2 and an alternator 3 on which a load is applied.

[0056] This engine 2 includes a speed regulator 4, which includes an injection computer, which calculates the injection quantity (or gas control) of the engine so that the rotational speed w can be kept constant at a nominal value w n This rating depends on the polarity of the alternator and the frequency of the current being searched at the output, eg 1500rpm for a frequency of 50Hz.

[0057] The engine 2 includes a speed sensor 5, which can be, for example, inductive, capacitive, or optical. The sensor 5 is for example arranged in front of a toothed ring gear driven in rotation by the motor and emits pulses at a frequency proportional to the rotational speed w.

[0058] The speed governor 4 receives this signal from the sensor 5 and calculates the appropriate level of fuel injection for maintaining this speed.

[0059] Such a...

Abstract

The invention relates to a method for adjusting injection of fuel into an engine (2) of a generation set (1). The generation set comprises an alternating current generator (3) driven by the engine. The engine comprises a velocity regulator. The method comprises the steps of sending an information item related to change of electric power and / or related to the electric power level to the velocity regulator (4) and adjusting the flow velocity of fuel injected into the engine (2) at least along with the change of the information item.

Description

technical field [0001] The invention relates to the regulation of generating sets. Background technique [0002] A generator set consists of an engine and an alternator assembly. Both the engine and the alternator are equipped with regulating devices in order to provide a nominal voltage and frequency. The engine is equipped with an electronic speed governor integrated into the engine's fuel injection system. The regulation of the engine speed may depend, inter alia, on measurements of the rotational speed of the engine shaft, for example by means of a sensor counting the number of teeth a toothed ring gear passes in front of the sensor per unit of time. [0003] From the signal sent by this sensor, the injection computer of the speed governor determines the level of injection to maintain the speed at a predetermined value, but has no direct knowledge of the level of load imposed on the engine because there is no economic means to communicate this load level to the comput...
