Method and system for restructuring, positioning and visualizing line loss of electric power system

Abstract

The invention aims to provide a method and a system for restructuring, positioning and visualizing line loss of an electric power system. The method comprises a step of displaying the line loss on the basis of an actual geographical map pattern, i.e., a Baidu map, and a step of inquiring the line loss on the basis of hierarchical retrieval and intelligent retrieval, wherein in the step of displaying the line loss on the basis of the geographical map pattern, a GIS (geographic information system) technique is adopted, and the electric quantity and the line loss are displayed step by step through a radiation graph and a connection graph which represent the hierarchical relation of an electric power unit; in the step of inquiring the line loss on the basis of the hierarchical retrieval and the intelligent retrieval, a distributed database is used as a platform, results are displayed through a Web terminal, and the line loss is inquired through simple operations of a mouse and a keyboard. Through the adoption of the method and system disclosed by the invention, comparison of audio-visual line loss visualized effects in a visualized graphical interactive manner is realized, a good angle for observing the line loss situation of a place is provided at the macro level, and a visualized problem of abstract line loss data on the basis of an actual geographical position is effectively solved.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a method and system for reconfiguration, positioning and visualization of power system line loss based on large customer data. Background technique [0002] The line loss rate is an important technical and economic index for the country to assess the power company, and it is one of the main contents for the power company to complete the national plan and the enterprise level. At the same time, the line loss rate is a comprehensive reflection of the management level of the power company. Therefore, line loss visualization is very helpful for power company staff to intuitively observe the line loss situation in a certain area in combination with geographical relationships to make line loss optimization decisions, and for ordinary people to understand the line loss situation without barriers, and has a good effect on line loss optimization. Supporting role. [0003] The pri...

Problems solved by technology

[0003] The prior art power system line loss management system usually describes the topological relationship between each monitoring point of each power grid with the attributes of each component in the database, and displays the analysis results of line losses at all levels in a tabular form. This data gives It is more about the numerical information of a power unit and the relationship information between power units, but cannot intuitively consider the influence of geographical relative position on line loss. This method leads to a macro grasp of the line loss situation in a certain area. difficulties, and for ordinary users, this data display method is also very unfriendly and incomprehensible
