Embodiment Construction

[0061] Such as figure 1 As shown in , the generator set 1 according to the invention comprises an engine 2 and an alternator 3 .

[0062] The engine 2 is advantageously a turbocharged engine, but the invention is not limited to a specific engine type.

[0063] The output of the alternator 3 is connected to, for example, a three-phase network, the rated rotational speed wn of the engine 2 is, for example, 1500 rpm, the rated frequency Fn is equal to, for example, 50 Hz, and the rated output between the phases of the alternator The voltage Un is eg 400V.

[0064] The engine 2 includes a speed regulator 4 which includes an injection computer which calculates the injection of the engine (or the control of the gases) so that the rotational speed w is as constant as possible at the nominal value wn .

[0065] The engine 2 includes a speed sensor 5, which may be, for example, inductive, capacitive, or optical. The sensor 5 is for example arranged in front of a toothed ring gear ...

Abstract

The present invention relates to a method for regulating a generator set. A method for regulating the output voltage of an alternator (3) of a generator set (1), the generator set comprising an engine (2) driving the alternator, the engine (2) comprising a speed regulation the alternator (3) comprising a rotor (19) having a pole wheel, the method comprising the steps of changing the current so that the output voltage of the alternator (3) suddenly reaches a voltage of a set point of the alternator lower than the voltage before the load increase, the change of the current in the pole wheel depends on the deceleration of the engine (2), The method of regulating the output voltage (U) is independent of the operation of the speed regulator.

Description

technical field [0001] The invention relates to the regulation of the alternator of a generating set. 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 relies, 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] With the signal sent by this sensor, the speed governor injection computer determines the level of fuel injection to maintain the speed at a predetermined value, but has no direct knowledge of the level of load imposed on the engine, since there is no economical means to communicate this load level...
