A plant for low-power preferably single-phase electrical supply to buildings for residential and non-residential use

摘要

A plant for supplying electric power to a building, comprising: a source of electric power (2); a plurality of electrical connections (3), supplied by the source (2) via a supply circuit, designed to enable the connection to the source (2) and a supply of power to the electric appliances (3); a control device (5) designed to: constantly measure the total electric power drawn by the electric appliances; compare the total draw measured with a pre-established maximum value of available electric power; block or limit the delivery of electric power to certain electrical connections (3) if the total electric power draw measured exceeds the pre-established maximum value; said control device (5) operating via a first main operating algorithm which assigns the electrical connections (3) given importance indices that define an overall scale of importance of the electrical connections (3); block or limit the delivery of electric power to an electrical connection (3) based on its importance index.
