Abstract

The embodiment of the invention provides a method for interpolating a voltage isometric curved surface and generating a pattern, which comprises the following steps of: calculating a weight vector of each lattice of a voltage isometric curved surface original network; merging a plurality of lattices with weight vectors less than preset threshold values in the original network into a lattice group to obtain L lattice groups; and carrying out interpolation calculation on the L lattice groups, carrying out interpolating by taking a center of the merged lattice groups as an inference, carrying out pattern generation on the interpolated lattice groups, and carrying out color lump filling on the pattern represented by the lattice groups in the pattern generation. The embodiment of the invention also provides a device for interpolating the voltage isometric curved surface and generating the pattern. According to the technical scheme provided in the embodiment of the invention, through the voltage isometric curved surface interpolation and pattern generation based on the lattice merging, the lattice number needing interpolation and drawing is reduced, and the speed of displaying the pattern is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of computer visualization, in particular, the present invention relates to a method and device for voltage contour surface interpolation and graphic generation. Background technique [0002] As the scale of the power grid increases, power dispatch operators often have to face hundreds of node data, and relying solely on tables and text display methods can no longer meet the requirements of power dispatch operators to monitor the power grid. With the development of computer visualization technology in recent years, the voltage contour surface map display technology based on geographic information has gradually attracted the attention of electric power workers. voltage contour surface Figure 1 Generally, the distribution of node voltage in the power system is regarded as continuous in the entire system coverage area, and color mapping and other methods are used to express the magnitude of the voltage ...
