Electricity production system

Abstract

Electricity production system comprising: an alternator (G) comprising a rotor and a stator; a means for driving the rotor (T); said alternator having a first operating mode, called alternator mode, in which the rotor is driven by the rotor driving means and the alternator supplies electricity and a second operating mode, called motor mode, in which the alternator is powered with electricity and the rotor supplies a motive mechanical force; a conversion means (MC) capable of powering the alternator in motor mode with a frequency which varies so that the rotor reaches a certain rotation speed; and at least one auxiliary electric equipment item (M). The conversion means comprises, for each of the auxiliary electric equipment items, a voltage converter (CT) capable of powering said auxiliary equipment item, a section of the voltage converters of all the auxiliary equipment items being capable of jointly powering the alternator in motor mode.
