Abstract

The invention discloses an intelligent remote control fault diagnosing method for a distribution network dispatching station. The method comprises the steps of performing whole-process real-time data acquisition on devices of a master station of the distribution station and communication between the devices, detecting and filtering remote control information of the distribution network dispatching station, starting a corresponding analysis task list, acquiring frame source codes of IO network protocol message stream from a network sniffing module through a switch sharing port, providing the frame source codes to an intelligent fault analysis module for fault analysis, classifying and matching the analyzed protocol message frame source codes to match out fault alarm information within a time cycle, and judging the matched fault alarm information to obtain a judged diagnosis result. The method can realize whole-process monitoring of a distribution network, intelligently diagnose remote control faults of grid information, determine the fault condition and analyze the fault reason, so as to quickly check the fault, improve the working efficiency, realize intelligence of fault elimination and ensure safety production of a grid.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an intelligent diagnosis method for remote faults of distribution network dispatching stations. Background technique [0002] The frequency and importance of remote control operations in the integrated technical support system for distribution network control have increased greatly compared to before, but when the distribution network control center uses the integrated technical support system for control, remote control operations sometimes fail. , due to the many links involved in remote control operation, the causes of faults are diverse and complex, and it often takes a long time to troubleshoot and solve faults, which directly affects the safe production of the power grid. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent diagnosis method for remote control faults of distribution network dispatching station, so as to s...
