A method of balancing an electrical distribution system including several generators implements a network divided into several subnetworks powered by ring-like swappers. The balancing of the network between the various generators available is obtained through switchings of subnetworks selected as a function of the order of switching of the swappers.

A method for the equal distribution of electric subnetworks among independent generators regardless of the number and availability of the generators in order to ensure power supply to all the subnetworks.

An electric network architecture for confined environments, includes: a main network including a plurality of electric wires capable of supplying in parallel electric power along the confined medium to a same load, wherein each wire is protected and can be insulated at each end; a primary distribution assembly including at least one primary distribution subassembly including a selection element connected to at least one of the wires and to a dedicated electric power source; at least one secondary distribution assembly connected to at least a portion of the main network and for powering at least one dedicated load, wherein each secondary distribution assembly includes at least one selection element connected to an output terminal to which an electric load is to be connected, the selection element being capable of closing or opening the electric link established between the output terminal and at least one of the wires of the main network.

A circuit breaker includes several elementary circuit breakers () arranged as several segments (), each suitable for powering several independent loads (). These provisions make it possible to improve the thermal equilibrium on each segment by distributing the heating over all the segments. The segmental circuit breakers are more particularly suitable for multi-wire networks which power a single load through a multitude of wires of the network in parallel.

The invention relates to wiring in a junction box using a printed circuit panel having on one of its edges N input terminals and on the opposite edge N output terminals, and between said two edges, a plurality of stages of individual connection devices each having two inputs and two outputs, the two inputs of a device being electrically connected to the two outputs of said device firstly by two direct connections and secondly by two crossed-over branch connections, the inputs of the devices of the first stage being electrically connected directly to input terminals, the outputs of the devices of the last stage being electrically connected directly to the output terminals, and between two successive stages, the outputs of each device of a lower stage are electrically connected to respective inputs of each device of the stage of higher rank. To personalize the wiring, either the direct connections or else the branch connections are interrupted in each of the devices.

The process is intended to optimize the operation of a digital protection system for protecting sets of busbars in the power station and uses a basic schematic of the electrical configuration of the power station obtained from information on the type of components used in the power station, and on the possible connections and accesses to said components. The information is assigned to management units of the digital protection system, said management units comprising peripheral measurement units and at least one centralization unit. A topological compilation process is implemented to provide a compiled schematic topology, and to provide a compiled assignment topology of the components in the power station and of their connections to the management units. A partial graph, whose structure depends on the type of information searched for and the status of each component of the power station, is obtained for each peripheral unit. A complete graph is then computed in one or more centralization units by algorithms which superpose partial graphs.

The method of correcting measurements is intended to limit the risk of unnecessary tripping of a differential phase current protection system that computes the vector sum of the currents of an area to determine the differential current between the inputs and outputs of said area in the course of regular tests. It is based on a statistical balancing method using measured current vectors each obtained from a measurement of the real current vector supplied at the time of each test by a current transformer, and it uses at the time of at least one test an iterative convergence algorithm for determining from the erroneous differential current vector formed by the sum of the measured current vectors the correction vector to be applied to each measured current vector in order to correct statistically the erroneous differential current vector.
