SYSTEM AND METHOD FOR MONITORING AND CONTROLLING ELECTRICAL NETWORK

摘要

A system and method for monitoring and controlling an electrical network includes a plurality of peripheral units installed at various nodes along the branches of the electrical network, each peripheral unit including current meters and voltage meters to measure current of a phase wire, current of the neutral wire, current of the ground wire, current difference between a phase wire and the neutral wire, voltage between a phase wire and the neutral wire and voltage between the neutral wire and the ground wire; switches connected to the phase wires and the neutral wires; and a central processing unit configured to: collect data from the meters, analyze the data to detect faults at the electrical network, and control the switches of the plurality of peripheral units, so as to disconnect faulty branches of the electrical network.

1. A system for monitoring and controlling an electrical network, the electrical network comprising branches, each branch comprising at least one phase wire, a neutral wire and a ground wire, and plurality of nodes, the system comprising:
a plurality of peripheral units installed at various nodes along the branches of the electrical network, each peripheral unit comprising:
at least one meter selected from a current meter and a voltage meter, to measure at least one of: current of a phase wire, current of the neutral wire, current of the ground wire, current difference between a phase wire and the neutral wire, voltage between a phase wire and the neutral wire and voltage between the neutral wire and the ground wire; at least one switch connected to at least one of: the phase wires and the neutral wires of at least one branch; and a central processing unit configured to:
collect data from the at least one meter;analyze the data to detect faults at the electrical network; andcontrol the at least one switch of the plurality of peripheral units, so as to disconnect faulty branches of the electrical network.
