A Boundless Cross Wiring Method for Distribution Feeder Single Line Diagram

Abstract

The invention discloses a boundless crossed line distribution method of a power distribution feeder line single line diagram. The boundless crossed line distribution method comprises the following steps: step 1, solving a node layout solution with minimum edge crossing of a network related connection line by utilizing a genetic algorithm; step 2, quantitatively describing and judging the edge crossing between non-related connection lines on the basis of a node layout basis, and finally, carrying out adjustment elimination; and finally, carrying out simple and regular topology connection line on the node which is arranged after optimization to form the power distribution feeder line single line diagram with clear logic. According to the method, the diagram layout of the power distribution feeder line single line diagram containing annular power supply equipment is effectively assisted; in an adopted node layout optimization algorithm, an established target function is easy to realize; meanwhile, a node layout position is limited by a grid, and geographic information of a power station is introduced to be used as constraint, so that the optimization solution space is reduced and the convergence efficiency of the algorithm is improved.

Description

technical field [0001] The invention relates to a borderless cross wiring method for a single-line diagram of a power distribution feeder. Background technique [0002] The one-line diagram of power distribution system is a kind of graphic data often used by departments such as operation inspection, planning, and dispatching. It is also the basic interface of various distribution network application systems such as production management and real-time dispatching. effect. In recent years, due to the flexible connection mode of the cable ring network formed by the ring network cabinet, the three-level structure of "high-voltage substation-ring network cabinet-distribution transformer" has become the mainstream solution for the construction of distribution networks in central cities, gradually replacing traditional pole-tower overhead lines Power supply form. In the automatic drawing of the single-line diagram of the power distribution network with ring power supply equipment...

Problems solved by technology

In the automatic drawing of the single-line diagram of the power distribution network with ring power supply equipment, since the spaced ring network cabinet often has multiple lead-out points in different physical locations, the general ring network drawing method is likely to cause a large number of edge crossings, which seriously affects the appearance of the graph and readability; and some algorithms to prevent intersections, such as the maze routing algorithm, can ensure that the lines are completely disjoint, but it is easy to make the lines seriously bent, which cannot reflect the logic of the graphics

At present, there is no literature related to the automatic drawing technology of the single-line diagram of the distribution network with ring power supply equipment
