Problems solved by technology

[0003] a. Poor versatility
At present, most of the graphical interfaces are customized for a specific function, such as the operation ticket system, fault analysis system, real-time line loss calculation system, etc. The main performance is that the equipment parameters are relatively simple, so it has to be done for different analysis functions Duplicate development work
[0004] b. Although the idea of ​​establishing an icon library is proposed in all power graphics software, for complex equipment in the power system such as ring network cabinets, switching stations, etc., the packaging methods and forms of these equipment are rarely given

Embodiment

[0113] The present invention can solve the shortcomings of current graphic development software, such as poor versatility and complicated icon library production, and also solves the problem of automatic management of icon library sharing and automatic detection and updating within the local area network, and provides great advantages for power distribution managers to draw single-line diagrams convenient.

[0114]The present invention proposes the design concept based on object-oriented GOO (graphic-object-oriented), uses GDI+ technology to realize the establishment of the power system object model, proposes a multi-level icon combination technology, and intelligently distinguishes different application scenarios to realize the model of one-line diagram drawing and operation.

[0115] see figure 1 , figure 1 It is the graphic element object structure diagram of this system, which is described as follows:

[0116] Drawing objects encapsulate basic graphic objects such as po...

Abstract

The invention relates to a graphic-object-oriented single-line diagram vector drawing tool of a distribution network. The system comprises an application scene module used for selecting a corresponding scene according to the demand of application, and an icon manufacturing module used for finishing the icon manufacturing. By adopting the graphic-object-oriented design idea, the establishment of the object model of a power system is realized by using a GDI+ technology, a multi-layer icon combination technology is provided and the different application scenes in the analytic process of the power system are intelligently distinguished. All the electric devices are realized through the corresponding graphics class, besides having the characteristics (such as member variable, interface, and the like) of the general class, the graphics class also comprises visible graphics which can be directly edited and operated through program codes and have good packaging and inheritance properties.

Description

Technical field [0001] The invention relates to a graphical object-oriented single-line diagram vector drawing tool for a distribution network, and mainly develops a drawing tool for the electrical single-line diagram of a distribution network. Background technique [0002] In the power transmission and distribution computer management system, whether it is operation tickets, simulated dispatch, power flow calculation, short circuit calculation or line loss analysis, it is necessary to draw and use a single-line diagram. In order to facilitate scheduling analysis and reduce the workload of dispatchers, with the development of graphical interfaces, people have developed a lot of power system graphics software, but these softwares generally have shortcomings: [0003] a. Poor versatility. At present, most of the graphical interfaces are customized for a specific function, such as the operation ticket system, fault analysis system, real-time line loss calculation system, etc. ...
