Abstract: A regulation process of an electrical distribution network that comprises a main power source, among one or more electrical sources, configured to impose on the network the voltage and frequency of a power circulating on the network to which one or more loads are connected. The process includes, in the event of a variation of one of the frequency or the voltage detected on the network, during a primary regulation, one adjustment step by the main source of the other between the frequency and the voltage, to maintain constant the ratio voltage/frequency.

Abstract: A method for detecting faults in a low voltage three-phase network including: checking if any of three phases of the three-phase network satisfies first conditions for a predetermined duration of time; if at least two phases satisfy the first conditions, detecting an inter-phase fault by checking if the current level in at least two phases exceed a threshold and if the corresponding current flows are in the same direction; if only one of the three phases satisfies the first conditions, for the phase which has satisfied the first conditions, checking if a second condition is satisfied and, in a positive case, detecting a mono-phase fault.
