Abstract:
1. A method for measuring and modulating in real time the electrical consumption of a plurality of electrical appliances powered from at least one electrical line of an electrical distribution network supplying a power feed signal at a nominal voltage and at a nominal frequency, said method comprising the steps of: measuring in real time the current consumed by each of the electrical appliances on each electrical line portion on which each electrical appliance is situated; extracting the frequency and the voltage of the electrical signal on each electrical line portion on which each electrical appliance is situated; calculating the difference in frequency by a data processing module, as an absolute value, between the extracted frequency and the nominal frequency of the distribution network and/or the difference in voltage, as an absolute value, between the extracted voltage and the nominal voltage of the electrical distribution network for each electrical line portion; generating an alert signal associated with an electrical line portion when the difference in frequency on this electrical line portion is greater than a predetermined frequency threshold value (f transmitting the electrical consumption of each of the electrical appliances and the alert signal to an external central platform; and sending, by said external central platform, selective isolation commands for certain electrical appliances, regardless of the position of these electrical appliances in relation to the electrical line portion for which the alert signal was generated.
