FIELD: controlling electrical energy consumed by household electrical appliances and other power consumers installed in house.
SUBSTANCE: proposed method used for controlling amount of electrical energy consumed by indoor users (FO, LS, FG, LB, CO), among them being indoor household appliances (A), includes connection of these users to supply mains (RE), each of these users (FO, LS, FG, LB, CO) being, essentially, electric load of power supply including steps for setting maximal permissible level of electric power consumption (Pmax) that can be generated by mentioned power supply; provision of mentioned electrical energy users (FO, LS, FG, LB, CO) with control means for controlling power requirement of respective users; measurement of instant total level of consumed electrical energy (PT)conveyed by mentioned power supply to mentioned system of household electrical appliances (A); transfer of information concerning instant total level of electrical power requirement (PT) to control means of each mentioned user (FO, LS, FG, LB, CO) through mentioned supply mains (RE); provision of control means of every electrical energy user (FO, LS, FG, LB, CO) for controlling power load sent by every user to mentioned electrical energy supply (CE) in response to mentioned information. Novelty is that mentioned information concerning instant total level of electrical energy consumption (PT) is transferred through mentioned mains (RE) at frequency depending on instant total level of electrical energy consumption (PT) measured by mentioned means (M3) and mentioned maximal permissible level of electric power consumption (Pmax).
EFFECT: enhanced stability of data transfer system.
