Abstract

The invention discloses a transmission grid single line diagram automatic design method based on combination primitives in the technical field of transmission grid single line diagram design. The method comprises analyzing T wiring into four grid combination primitive models, and analyzing common wiring into two grid primitive models; selecting the T wiring as initial T wiring randomly, matching the initial T wiring with any combination primitive models randomly and arranging the matched initial T wiring in a canvas center to form an initial whole M; screening strong correlation T wiring from the T wiring which is not selected, and selecting T wiring randomly if the strong correlation T wiring does not exist; performing combination primitive optimization and layout optimization on the combination primitive models according to an objective function F to obtain final combination primitive models and arranging the final combination primitive models into the initial whole M; performing overlap operation on the whole M, and deleting repeated primitives; and adding corresponding combination primitive models of T wiring which is not selected into the whole M according to the method. The transmission grid single line diagram automatic design method based on combination primitives solves the automatic layout problem of multi-T-wiring transmission grid single line diagrams.

Description

technical field [0001] The invention belongs to the technical field of transmission network single-line diagram design, in particular to an automatic design method of transmission network single-line diagram based on combined graphic elements. Background technique [0002] Domestic scholars introduced the simulated annealing optimization algorithm, and took the total length of the line and the number of intersections as the objective function to try the automatic layout and drawing of the single-line diagram of the transmission network, and achieved good results. However, the optimal weight factor in the objective function varies with the model. Changes require manual adjustment, which is inconvenient to select. Another scholar obtained the initial layout through the penalty function method, combined with the characteristics of the one-line diagram, proposed a path-finding algorithm that allows intersections, and the practicability and efficiency of automatically generating ...
