An Automatic Layout Method of Grid Diagram Based on Geographical Information of Plants and Stations

Abstract

The present invention provides an automatic layout method of power grid grid diagram based on power station geographic information, comprising the following steps: importing power grid structure data into the automatic layout system; forming an initial power grid grid diagram; automatically adjusting and optimizing the location of power grid; The automatically adjusted and optimized factory station position is corrected. The invention can realize the automatic layout of the network frame diagram based on geographical information, and the graphics are more intuitive; it supports the timely update of the graphics when new plants are added or deleted, which reduces the omissions and errors of artificial editing graphics, and greatly improves the graphics model. maintenance efficiency.

Description

Technical field [0001] The invention belongs to the technical field of power system dispatching automation, and specifically relates to an automatic layout method of a power grid network frame diagram based on geographic information of power plants. Background technique [0002] In the power grid dispatching system, the monitoring of the line and the distribution of power flow between plants and stations is the responsibility of dispatching automation. In the current monitoring system, drawing power system network topology diagrams and power grid flow diagrams are manually drawn by maintenance personnel or engineers based on the actual topological structure of the monitored power grid using the dispatch system drawing tool. [0003] In order to ensure the rationality of the operation and control results of the energy management system of the dispatch center, a global power flow model needs to be realized through the interaction of real-time models between the upper and lower dispat...

AI Technical Summary

Problems solved by technology

Due to the shortcomings of untimely update, time-consuming, error-prone, inconvenient maintenance, and unsightly maintenance, the method of manually maintaining power flow diagrams is no longer applicable. It is necessary to automatically generate global power flow diagrams based on the global power grid model. Geographical information of stations (power plant stations, 500kV stations, provincial capital stations, etc.), the grid diagram is automatically drawn by software, with small workload, beautiful picture and easy maintenance

[0004] In the past, the power grid grid diagrams used in dispatching communication centers above the provincial level were drawn manually by maintenance personnel using the drawing tools of the power system dispatching automation software platform. Data information needs to be placed manually. In the case of a large network scale, drawing Grid diagrams often require several days of work. Adding new plants and lines may require adjustments to the layout and wiring of the original grid diagram. In order to add new data information, it may also be necessary to adjust the overall screen structure, all of which are done manually It is often impossible to achieve efficient, accurate and reliable results

Taking the grid diagram of the national power grid as an example, because it needs to display the grid structure of each province, the scale is very large, and the probability of new plants and stations being put into operation is higher than that of a certain province. The grid grid diagram needs to be constantly revised. Every modification requires re-layout and routing, which can take days to make just one modification

All in all, the original technical means cannot adapt to the needs of the rapidly developing grid scale, nor can it meet the needs of dispatchers for faster and more comprehensive grid information
