The invention relates to a system for connecting a decentralized, single-phase generator to one phase or another of a three-phase grid. Said system includes: - an analyzer, providing the values VØ1, VØ2, and VØ3 of the voltages of the three phases and the value of the current I flowing towards one of the three phases; - a processor capable of making the following relations comply: (VØi + θØi*Ι)β < VØi+1 or i+2, VØi < VØi+1 or i+2' I > n Imax, wherein i = 1, 2 or 3, modulo 3, αØi is a sensitivity coefficient, β is a weighting coefficient greater than 0.5, n is a coefficient less than 0.5, and Imax is the maximum current that the generator can provide; - a switch for switching the output of the single-phase generator from the phase i+1 or i+2 to the phase i if the three relations above are satisfied; and - a memory for storing, upon each instance of switching, the value αØi of the sensitivity of the phase i. |
