Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] The embodiment of the present invention provides a setting calculation method for automatically generating a fixed value switch fixed value diagram of a distribution network line. By generating a visual diagram of the protected fixed value, the details of the protected fixed value on the current distribution line can be clearly understood. It can facilitate the relevant personnel to quickly and conveniently troubleshoot and locate the proble...

Abstract

The invention relates to the technical field of power grids, in particular to a setting calculation method for automatically generating a fixed-value switch fixed-value diagram of a distribution network line; by generating an intuitive diagram of the protection fixed value, the protection setting on the current distribution line can be clearly understood The value details can facilitate the relevant personnel to quickly and conveniently troubleshoot and locate the problem; the steps of automatic mapping through the method of tree branch flashback detection are as follows: first, the current distribution line is segmented, layered, and typed before automatic mapping Carry out precise division; the beneficial effect of the present invention is that it can improve the calculation efficiency of the protection fixed value, and can improve the management level of the operation state of the power grid, thereby ensuring the safe and stable operation of the power system.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a setting calculation method for automatically generating a fixed value switch fixed value diagram of a distribution network line. Background technique [0002] At present, the 10kV distribution network protection setting work has many problems such as manual intervention, heavy workload, low calculation accuracy, low calculation efficiency, and unintuitive. If the relay protection setting value adjustment occurs, the relevant personnel need to return to the office to redo it Protection fixed value calculation cannot be fully guaranteed in terms of efficiency and accuracy. Through in-depth research, this project carries out research work on distribution network intelligent protection fixed value calculation and fixed value management, and realizes a complete solution for intelligent protection fixed value visual diagram, reducing confusion caused by relay protection setting e...
