Abstract

The invention provides a power distribution network planning graph visibility optimization method. The power distribution network planning graph visibility optimization method comprises the followingsteps of S1, performing power distribution network planning graph global visibility optimization based on a space-limited FR algorithm; S2, carrying out power distribution network planning graph densearea identification based on CD-TIN; S3, carrying out FR algorithm parameter optimization based on a grid method; and S4, on the basis of the optimal parameter FR optimization result, carrying out power distribution network planning graph local dense region visibility optimization based on an FE algorithm. According to the method, global-to-local distribution network planning graph node layout optimization is realized, the included angle between homologous dense lines is increased, and the optimized distribution network planning graph can meet the requirements of clear topological relation between the lines and distribution facilities and accurate spatial positions of the distribution facilities.

Description

technical field [0001] The invention relates to the fields of graph visualization and electric power, in particular to a method for optimizing the graph visibility of distribution network planning. Background technique [0002] In recent years, with the rapid development of the economy and the rapid growth of electricity consumption, the scale of the distribution network has expanded rapidly. According to statistics, my country's current high-voltage distribution network has reached 440WKM, and it is expected to reach 505WKM in 2020. At the same time, urban construction continues to accelerate, and power planning is out of touch with urban planning, resulting in very chaotic spatial distribution of distribution networks. The huge distribution network data with dense spatial distribution and complex structure is increasingly unfavorable for the spatial visualization of distribution network. [0003] Distribution network space visualization refers to the use of computer techn...
