Embodiment Construction

[0031] Because the distribution network has the characteristics of huge grid structure, large amount of monitoring information, wide coverage, frequent operation and other characteristics, the corresponding operation monitoring work is a difficult task for the grid dispatchers. For this reason, it is necessary to provide a refined and intuitive graphical expression method for the operation monitoring of the distribution network, so as to facilitate the real-time monitoring of the load level of the distribution network by the grid dispatcher.

[0032] After in-depth research by the inventor, it is considered that it is not appropriate to adopt a graphical expression method based on the grid network structure and geographical relationship. This graphical expression has the defect that it cannot fully reflect the overall scale of the distribution network. For this reason, the inventor proposes to use a multi-circle, multi-region, and multi-color block visualization graph to reali...

Abstract

The invention relates to a visualized implementation method oriented to operation load state monitoring of a distribution network. The visualized implementation method comprises the following steps of: (1) setting a circuit state monitoring limit value and a load level color configuration of the distribution network; (2) selecting circuits to be monitored, acquiring the number and names of the circuits to be displayed, and carrying out sector-shaped partitioning on an initial circle according to the number of the circuits; (3) carrying out topological analysis on the distribution network to form a tree network of the distribution network; (4) carrying out breadth and depth topological search on the circuits to form a tree structure level record; (5) drawing a circuit level relationship graph according to the tree structure level record; (6) calculating load ratios of the circuits according to the measuring data of the circuits; and (7) filling a sector-shaped region where the circuits are located according to the load ratios and the load level color configuration. According to the visualized implementation method disclosed by the invention, the generated visualized graph is adaptive to the characteristics of the distribution network; simple and intuitive expression and high information enrichment are achieved; and the load monitoring capability of a real-time monitoring system of the distribution network can be remarkably promoted.

Description

technical field [0001] The invention relates to a distribution network monitoring method, in particular to a visualization implementation method for distribution network operation load state monitoring, and belongs to the technical field of distribution automation. Background technique [0002] The real-time monitoring system of the distribution network mainly collects the operation status data of the distribution network equipment through the monitoring terminals distributed in different places, and collects them in the monitoring system of the distribution master station to realize the overall monitoring of the operation status of the distribution network. It is one of the important pillars for safe, economical and reliable operation of power distribution system. [0003] The load status (load rate) of distribution network is an important indicator of distribution network security, and it is also an important monitoring object of distribution network real-time monitoring s...
