Feeder automation processing method applying 5G network slice communication technology

Abstract

The invention discloses a method for realizing feeder automation processing by applying a 5G network slice communication technology. The method comprises the following steps of: processing a fault by adopting an intelligent distribution and relay protection mode when the fault occurs; judging whether the fault is processed after the fault occurs for X seconds, if so, informing operation and maintenance personnel by the master station, and processing the fault by adopting a voltage-time type + relay protection mode; and after Y seconds, judging whether the fault is processed or not, notifying operation and maintenance personnel by the master station, processing the fault by adopting'master station centralized type + relay protection ', and notifying a result to the line operation and maintenance personnel. The method has the beneficial effects that the advantage of quick fault isolation of relay protection is combined with the fault isolation of three modes of intelligent distribution, voltage-time type and master station concentration and the function of non-fault area power supply, so that the influence caused by fault current can be quickly reduced; faults are rapidly, stably and accurately isolated, power supply of non-fault areas is recovered, power supply reliability is improved, and user experience is optimized.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a feeder automatic processing method using 5G network slicing communication technology. Background technique [0002] In recent years, with the rapid development of my country's science and technology and economy, power grid construction has also entered a period of rapid development. The power grid has developed from a sporadic isolated grid with low coverage, low connectivity, and low voltage to a power grid with the widest coverage, the most powerful energy resource allocation capability, the largest grid-connected new energy installed capacity, and the most high-voltage transmission lines in the world; The grid with a low level of safe operation has developed into one of the grids with the highest level of safe operation in the world, and power supply has entered a stage of high reliability. [0003] As the link between the power grid and users, the distribution network ...

AI Technical Summary

Problems solved by technology

[0004] Intelligent distributed and centralized types have high requirements for communication and require optical fiber support, but the cost of optical fiber laying and maintenance is high, especially in urban areas, and it is difficult to solve the protection configuration problem of distribution network points without optical fiber coverage, so it is not suitable large-scale promotion

The voltage-time type takes too much time in the fault handling process, and will cause multiple power outages in non-faulty areas, which is not friendly to user experience

[0005] At present, on-site feeder automation can reduce the fault isolation time and fault blackout area to a certain extent, but it will cause the substation outlet switch to trip and the line to have a short-term power outage, which not only brings a large current impact to the system, but also brings inconvenience to customers. good user experience
