Abstract

The invention discloses a working method of a power grid intelligent controller for an overhead line, and relates to the technical field of power grid intelligent control. The method comprises a monitoring host, a communication module, a closing/opening module, an overload protection module, an electric leakage protection module and a microcontroller, and comprises the following specific steps: installing each module in an intelligent power grid circuit; establishing communication connection between the monitoring host and the communication module to realize data transmission; through data transmission of the monitoring host, the closing/opening module is remotely controlled, and on-off control is carried out on the whole intelligent power grid circuit. When the intelligent power grid is in a closed state, the overload protection module and the leakage protection module monitor the load condition and the leakage condition in the circuit in real time, and when the overload and leakage conditions occur, the overload protection module and the leakage protection module control the closing/opening module to cut off the whole circuit through the microcontroller. And the data is transmitted to the monitoring host through the communication module. According to the invention, electric arc and excitation inrush current can be avoided.

Description

technical field [0001] The invention relates to the technical field of power grid intelligent control, in particular to a working method of a power grid intelligent controller for overhead lines.
