INTELLIGENT ELECTRIC GRID MANAGEMENT SYSTEM AND METHOD

摘要

An intelligent electric grid management system and method includes at least one feeder line controller, which is arranged between a secondary power transforming station and at least one power supply feeder line to receive high voltage power and a control instruction from the secondary power transforming station and to store and set, in advance, digital code data of each power supply feeder line, an smart meter of a user end, appliance loads, and priority cutoff levels, a plurality of smart meters, which is each connected between the distribution line of each user end and at least one power feeder line, wherein the smart meter and the feeder line controller transmit therebetween a user end load ON/OFF control signal and a load state detection feedback signal through the power supply feeder line by means of the power line communication protocol; and a plurality of intelligent load receptacles, which is connected to the receptacle power line of the distribution line of the user end and the household appliance loads so that based on the power grid overall power requirement state and the priority cutoff level, the feeder line controller controls, through the smart meter by means of the power line communication protocol, each of the intelligent load receptacles to supply or cut off power to the household appliance load connected thereto.

1. An intelligent electric grid management system, comprising:
at least one feeder line controller, which is arranged between a secondary power transforming station and at least one power supply feeder line to receive high voltage power and a control instruction from the secondary power transforming station and to store and set, in advance, digital code data of each power supply feeder line, an smart meter of a user end, appliance loads, and priority cutoff levels and to transmit user end load ON/OFF control signals and receive load state detection feedback signals by means of a power line communication protocol; a plurality of smart meters, which is each connected between the distribution line of each user end and at least one power feeder line, wherein the smart meter and the feeder line controller transmit therebetween a user end load ON/OFF control signal and a load state detection feedback signal through the power supply feeder line by means of the power line communication protocol; and a plurality of intelligent load receptacles, which is connected to the receptacle power line of the distribution line of the user end and the household appliance loads so that based on the power grid overall power requirement state and the priority cutoff level, the feeder line controller controls, through the smart meter by means of the power line communication protocol, each of the intelligent load receptacles to supply or cut off power to the household appliance load connected thereto.
