Distribution network single line diagram graph splitting method

Abstract

The invention discloses a distribution network single line diagram graph splitting method, and relates to a distribution network drawing method. The currently used single line diagram can meet the scheduling requirement, but cannot meet the operation inspection requirement. The method comprises the following steps: generating a single line diagram general diagram; according to the size and contentof a printing page of the generated single line diagram general diagram, judging whether the single line diagram general diagram reaches the definition meeting the operation inspection requirement ornot; if so, directly ending; if not, entering the next step; reminding a user to split the total graph; and after the user selects the splitting points, splitting the single-line diagram general diagram according to the selected splitting points, and re-arranging the sub-diagram to obtain a diagram. According to the technical scheme, a total graph mode and a branch graph mode are provided for automatic generation of the single-line graph, the total graph is that one feeder line corresponds to one single-line graph, and the total graph is mainly applied to dispatching automation. The graph division mode is mainly applied to operation and inspection departments. The application range of the single line diagram is enlarged, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a method for drawing a distribution network, in particular to a method for splitting graphics of a single-line diagram of a distribution network. Background technique [0002] The automatic drawing of the single-line diagram of the power system distribution network is an important part of the advanced application of the power system distribution network, and it is an indispensable graphic for the daily work of the distribution network dispatching and inspection department. The dispatching department requires the one-line diagram to be clear, focusing on the relationship between switches and lines. Since it is mainly displayed on a computer or a large screen, it is relatively easy to implement. The transport inspection department requires the one-line diagram to be helpful for operation and maintenance, and can be brought to the work site. Due to the limitations of the cultural structure, age structure, and working environment o...

Problems solved by technology

The transport inspection department requires the one-line diagram to be helpful for operation and maintenance, and can be brought to the work site. Due to the limitations of the cultural structure, age structure, and working environment of the transport inspection personnel, it is necessary to print out the one-line diagram and bring it to the site for operation (A3 or A4 Printing), so it is required that the drawing must be clear, and the graphic elements and label fonts should be large (so that older staff can see clearly), especially the 20Kv power grid has a large load capacity, and the single-line diagram has a large range and many contents. If only It is difficult to produce a one-line diagram to meet the needs of transportation and inspection

[0003] At present, the one-line diagram in the State Grid PMS2.0 system used by the power company can meet the needs of dispatching, but it cannot meet the requirements of inspection. The main reason is that the printed text is too small, especially the one-line diagram with many contents. Small elements and small characters are not clear to the human eye, which has become the pain point and difficulty of the current one-line diagram automatic drawing
