Abstract
An annex supply system for an electrical power plant includes an energy extraction network configured to receive AC current from a main production unit, a main auxiliary network coupled to the extraction network, and a secondary supply unit. The secondary unit includes a storage element coupled to a means for reversible conversion from direct to alternating current that is controllable to selectively (i) charge the storage element from the main auxiliary network, and (ii) discharge energy from the storage element to the main auxiliary network. The secondary unit is configured to (i) provide a first power profile at least sufficient to provide services to a transmission network, and/or (ii) provide to the main auxiliary network a second power profile required to operate auxiliary equipment in case of inoperability of a normal power supply source of the main auxiliary network.
