Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] refer to figure 1 and figure 2 , a progressive automatic generation method for the visual layout of transmission network power station nodes, including the following steps:

[0035] Step 1: Obtain all plant and station nodes that need to be laid out from the database, a total of n nodes, and the node set is recorded as Ni.

[0036] Step 2: Check whether there is a line between every two nodes Ni and Nj, if it exists, set it to Lij, if it does not exist, this Lij does not exist.

[0037] Step 3: Randomly generate the x-coordinates and y-coordinates of all nodes, denoted as Ni(x, y). The value range of x and y is an integer between 0 and 1000.

[0038] Step 4: Set node traversal count i=1.

[0039] Step 5: Set the moving components of the node Ni on the x-axis and y-axis as dix=0 and diy=0.

[0040] Step 6: Set node traversal count j...

Abstract

The invention relates to a method for progressively and automatically generating a visual layout of nodes of a power transmission network plant. The method comprises the following steps of: (1) initializing node information and randomly arranging for the first time; (2) automatically arranging the nodes, namely setting a node traversing count i as 1 (traversing from 1 to n), setting moving components of a node Ni on an x axis and a y axis as dix which is equal to 0 and diy which is equal to 0 before traversing, and performing the following operation during traversing: setting a node traversing count j and traversing from 1 to n, and correcting the dix and the diy according to coordinates of Ni and Nj; judging whether connection Lij between the nodes Ni and Nj exists or not, if the connection Lij exists, correcting the dix and the diy according to the connection of the Ni and the Nj; and modifying Ni(x,y) according to the dix and the diy; and (3) finishing the automatic generation process and outputting results, namely the coordinates (x,y) of all nodes. The method has better layout effect, improves the calculation speed effectively, and can meet a visual habit of dispatching personnel.

Description

technical field [0001] The invention relates to the technical field of automatic layout of transmission network power station nodes in an electric power system, in particular to a progressive automatic generation method for transmission network power station node layout. Background technique [0002] With the continuous expansion of the transmission network in the power system, the operation department needs to monitor and inspect thousands or even tens of thousands of grid nodes. For such a huge number of nodes, the power grid automatic control center must be able to clearly display a large number of plant nodes and the line connections between them on the computer, so as to facilitate the query and analysis of dispatchers. [0003] To date, a large number of transmission network plant and station structures have been manually drawn by dispatchers. Manually drawing transmission grid station layouts has the following advantages: [0004] 1. The layout conforms to the usage...
