A method of automatic expansion of graph space for distribution network

Abstract

The invention discloses a graph space automatic-expansion method for a power distribution network. The method comprises the following steps of (1) opening a graph database of the power distribution network; (2) selecting a position as an expansion point with a graph space expansion requirement in the graph database; (2) setting the expansion amount of the expansion point in a coordinate direction in the graph database; (4) calculating and expanding the area of a drawing where the graph database is according to the expansion amount by using a computer; (5) setting an expansion direction in the graph database, and performing expansion at the position of the expansion point towards the expansion direction according to the expansion amount to finally form a blank area consistent with the expansion amount and the expansion direction at the position of the expansion point; (6) storing a expanded graph space after expansion, and ending the method. According to the method, convenient and simple expansion operation can be provided for a dispatcher to facilitate the addition of all other newly-added equipment of the power distribution network in the reserved blank area, the method is implemented completely by analytical calculation, and is convenient to operate, and the graph maintenance workload of the dispatcher can be reduced.

Description

technical field [0001] The invention relates to the technical field of power system operation and analysis, in particular to a method for automatically expanding graphic space for distribution networks. Background technique [0002] With the continuous increase and change of distribution network equipment under the jurisdiction of power dispatching, if there is any increase, change of equipment or change of wiring mode, the dispatcher needs to perform synchronous maintenance and update, and the daily editing and maintenance covers a wide range and a large amount. In the usual drawing software, the graphics components are in a fixed position after the drawing is completed. If you need to insert a new device, you must first manually shift the original graphics before inserting it. It is very difficult to move and insert when the screen is full of devices. Moreover, errors in connection and the like are prone to occur during the movement. Contents of the invention [0003] T...

In the usual drawing software, the graphics components are in a fixed position after the drawing is completed. If you need to insert a new device, you must first manually shift the original graphics before inserting it. It is very difficult to move and insert when the screen is full of devices. And in the process of moving, it is easy to make mistakes in connection and other aspects
