Visualization error correction method of power distribution network topology model

Abstract

The invention relates to the technology for processing a topology model in power distribution automation, in particular to a visualization error correction method of a power distribution network topology model. The visualization error correction method of the power distribution network topology model is characterized by including the steps that a CIM model is obtained from a GIS to be used as a power grid topology model which is to be corrected and is led in by a DMS, a standard SVG is acquired to be used as an error correction standard, the CIM model is verified first, afterwards, apparent errors, electrical disconnection and wrong connection are sequentially detected, wrong multilevel graph comparison and analysis of electrical topology are examined in detail, and meanwhile interaction control over the topology (power supply area) on the whole network graph is realized so that a coloring test can be promoted. According to the method, the topological relation is displayed in imaging and visualization modes, the visualization check and error correction of the power distribution network topology model are achieved, hence, the correct model topology is provided for the DMS, and the DMS advanced application functions such as the centralized feeder automation function and the network reconstitution function can be better achieved. Solid technical support is provided for power distribution operation, the scheduling intelligent degree and the improvement of working efficiency.

Description

technical field [0001] The invention relates to a topology model processing technology in distribution automation, in particular to a visual error correction method for a distribution network topology model. Background technique [0002] Introduction to related terms: [0003] The main station of the distribution automation system (that is, the distribution network dispatching control system, referred to as the DMS system) mainly realizes the basic functions such as data collection and monitoring of the distribution network and the extended functions such as analysis and application, and serves the distribution network dispatching and distribution production. [0004] Power grid geographic information system (GIS system for short), integrates digital geographic information, power grid structure model and its topological relationship, power equipment graphics and account, electrical wiring diagram, equipment operation status and other information, and provides information for...

Problems solved by technology

[0006] However, due to the fact that there are a large number of model topology errors in the graphs imported from the GIS system to the DMS system, it seriously affects the deepening of the advanced application functions of the DMS system.

In addition, the error correction and maintenance function of the original matching model is realized by directly analyzing the CIM-XML object model file, which is displayed in the form of an error log alarm. , leading to the lag in the development of advanced functions that require high topology quality, such as feeder automation, and the application of distribution dispatching technology support functions based on grid topology analysis, thus affecting the intelligence of distribution operations and dispatching and work efficiency
