Uninterrupted electric power supply system

Uninterrupted electric power supply system, that comprises:

• control means (5);
• a synchronous machine (1) that comprises electric motor means (1M) and alternator means (1A), the electric motor means being arranged to be fed by the network (10), said electric motor means (1M) being mechanically connected to the alternator means (1A) to provide energy to the alternator means while they receive electric energy from the network (10);
• first mechanical energy supply means, that comprise an internal combustion engine (2), arranged to provide mechanical energy to the synchronous machine (1) under the control of the control means (5), the internal combustion engine (2) being connected to the synchronous machine by means of first mechanical coupling means (8);
• second mechanical energy supply means, connected to the synchronous machine by means of second mechanical coupling means (9) in such a way that they can provide mechanical energy to the synchronous machine (1) under the control of the control means (5);
• pressurized fluid accumulation means the fluid being gaseous or liquid;
• wherein
• the second mechanical energy supply means are comprised of a turbine (3) that includes
• a shaft (11), connected to the synchronous machine (1) by means of said second mechanical coupling means (9);
• a plurality of nozzles (16);
• means to convey pressurized fluid from the pressurized fluid accumulation means to the nozzles (16);
• means to release pressurized fluid in such a way that the fluid is expelled through the nozzles (16);
• the nozzles (16) being arranged in such a way that the expulsion of fluid through the nozzles (16) provides turning torque to the shaft (11) of the turbine (3);
• and wherein
• the control means (5) include
• means to control the expulsion of fluid through the nozzles (16);
• characterized in that the nozzles (16) are connected to the shaft (11) of the turbine (3) in such a way that they turn with said shaft (11), the nozzles (16) being arranged in such a way that the expulsion of fluid through the nozzles (16) provides turning torque to the shaft (11) based on a reaction phenomenon.
