Automatic power network wire frame map layout method based on factory geographic information

Abstract

The invention provides an automatic power network wire frame map layout method based on factory geographic information. The automatic power network wire frame map layout method includes inputting data of power network structure into an automatic layout system, forming an initial power network wire frame map, automatically adjusting and optimizing factory positions and correcting factory positions after automatically adjusted and optimized. The automatic power network wire frame map layout method can realize automatic power network wire frame map layout based on the factory geographic information, graphs are more intuitive, graphs can be updated timely when factories are newly added or deleted, careless omission and failure from man-made graph compilation are reduced, and efficiency of artwork maintenance is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to an automatic layout method for a grid diagram of a power grid based on geographical information of power plants. Background technique [0002] In the power grid dispatching system, it is the responsibility of the dispatching automation to monitor the stations, the lines between the stations and their power flow distribution. In the current monitoring system, drawing power system network topology diagrams and power grid flow diagrams is manually drawn by maintenance personnel or engineers using dispatching system drawing tools based on the actual topology of the monitored power grid. [0003] In order to ensure the rationality of the operation and control results of the energy management system of the dispatch center, it is necessary to realize the global power flow model through the interactive real-time model of the upper and lower...

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inconvenient maintenance, and unsightly maintenance, the method of manually maintaining power flow diagrams is no longer applicable.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
