<p>The system (1) has a sub-station (110) including a transformer (111) between first and second collection circuits (100, 200) conveying respective voltages. Another transformer (310) is arranged between the second circuit and a third collection circuit (300) conveying a third voltage. An inverter (410) is associated with a fourth collection circuit (400), which is direct current collection circuit, and arranged between the third circuit and the fourth circuit. The third circuit collects power of fourth circuit to which it is connected.</p> |
