1. Process for balancing an electric distribution system comprising an electric network, said network being divided into sub-networks, comprising N generators, N greater than or equal to three, each generator supplying a part of the network when said generator is operational, in which network each sub-network is supplied at a given moment by only one generator, in which network each sub-network is associated, by a ring permutator (1) to which it is connected, with a combination of P generators that define an order of connection, among the possible connections, of said sub-network to at least three—P being greater than or equal to three—of the generators among the N generators and in which balancing process:
in a first step (110) are determined:
Wmaxnetwork: the maximum power available on the network, equal to the sum of the maximum powers WmaxGi that can be delivered by each of the operational generators Gi;for each operational generator Gi the actual power delivered WGi; in a second step (120) are calculated for each of the operational generators:
a new theoretical power for balancing WneGi that takes into account desired conditions for distribution of the loads and such that sum (WneGi)=sum (WGi) of the operational generators Gi, and;a power variance DWi=WGi−WneGi between the actual power and the new theoretical power for balancing; in a third step (130) are identified the sub-networks supplied by generators in positive imbalance, i.e., whose power variance DWi is positive, and that can be reassigned by a ring permutator (1) to a generator in negative imbalance, i.e., whose power variance DWi is negative; in a fourth step (140), ring permutators (1) connected to the sub-networks identified during the preceding step (130) are actuated to supply all or part of said sub-networks by generators in negative imbalance. |
