Problems solved by technology

[0002] At present, in the practice of displaying the load of distribution network transformers, most of them display the load of a single distribution network transformer, and seldom display the load of distribution network transformers as a whole based on GIS maps. When displaying the load of transformers, due to the huge number of transformers in the distribution network, the performance of the WEB page is limited. If the load of each transformer is rendered, the display performance and display effect are often not ideal, or the two-dimensional effect is used. When thermally displaying the transformer load, the display effect is not intuitive enough, and it is necessary to find a suitable display method for the overall load distribution of the distribution network

Embodiment 1

[0030] The embodiment of the present invention provides a GIS-based distribution network load distribution display method, including:

[0031] 1. Based on the longitude and latitude, the grid calculation is performed on the distribution network load, the average load rate of the distribution network, and the maximum load rate of the distribution network.

[0032] Rasterization calculations include:

[0033] S1. Obtain the longitude and latitude coordinates of each distribution network transformer, and determine the longitude and latitude grid to which each distribution network transformer belongs based on the preset longitude and latitude grid; generally retain the 2-digit decimal precision of the longitude and latitude of the distribution network transformer for the convenience of calculation As the longitude and latitude of the longitude and latitude grid to which it belongs, the size of the longitude and latitude grid is about 1.23 square kilometers.

[0034] S2. Acquire t...

Abstract

The invention discloses a GIS-based power distribution network load distribution display method and apparatus. The method comprises the steps of performing rasterizing calculation on a power distribution network load, a power distribution network average load rate and a power distribution network maximum load rate based on longitude and latitude; superposing a three-dimensional histogram on a GIS map through a WEB front-end page to display the power distribution network load, the power distribution network average load rate and the power distribution network maximum load rate which are obtained through calculation; according to the method, the problems that when the power distribution network load is displayed on the basis of a map, the number of power distribution network transformers is too large when the power distribution network transformer load is directly displayed, and load display in a two-dimensional mode is not visual enough are solved; the distribution and fluctuation change conditions of the load and the load rate of the power distribution network can be visually seen, meanwhile, the data volume displayed at the front end is controlled, and good display performance is achieved.
