Abstract

The invention provides a bus grounding fault processing method based on main and distribution integrated big data analysis, and the method comprises the following steps: recognizing a grounding fault through employing a multi-dimensional data intelligent alarm technology, if a power distribution automation system recognizes the grounding fault, processing the grounding fault based on an integrated sequence control system, and carrying out the processing of the grounding fault. Otherwise, identifying the ground fault by using a main and distribution intelligent alarm collaborative optimization technology, identifying the ground fault by using a power distribution network FA and intelligent alarm collaborative optimization technology, and processing the ground fault based on a power distribution network ring network alarm logical reasoning technology. According to the method, man-machine efficient interaction is utilized, the intelligent dispatching level of a power grid is improved more quickly and more efficiently with higher management force, higher innovation force and higher execution force, bus grounding fault handling is improved to 6 minutes from 30 minutes, and lean management is achieved. The main-distribution integrated technology is realized to support intelligent auxiliary decision making, and the accuracy of fault alarm and fault positioning is improved. The power recovery efficiency is effectively improved, the power supply service quality is improved, the manpower and material resource cost is saved, and resource optimization management is realized.

Description

technical field [0001] The invention relates to the technical field of ground fault alarms, in particular to a bus ground fault processing method based on big data analysis of master-distribution integration. Background technique [0002] At present, there are many hills and hills in the power supply area of ​​the medium-voltage power grid in the western region, and the power supply lines pass through economic crops such as banana forests and fast-growing eucalyptus. The occurrence of ground faults seriously affects the quality of power supply. Due to the excessive workload of network area operation and maintenance, insufficient power grid operating conditions, and personnel skills that need to be improved, etc., it will affect the emergency handling capacity of ground faults, prolong the recovery time, and further reduce the reliability of power supply. Therefore, it is urgent to study the optimization method of busbar grounding alarm diagnosis to improve the efficiency of ...
