A method and device for generating a primary topology connection diagram of a smart substation

Abstract

The invention relates to a method and device for generating a one-time topology connection graph of an intelligent substation. By introducing a concept of interval styles, one-time intervals and styles are combined; according to practical layout characteristics of one-time intervals of the substation, device layouts in the intervals are flexibly adjusted to form interval styles of different styles, and finally a one-time interval style library is formed. During generation of the one-time interval styles, the interval style is subjected to topology connection verification, topology connection results are presented in an imaged mode, visualization and verification of topology connection in the intervals are achieved, and the probability of one-time device leak connection and wrong connection in the intervals is effectively reduced. The one-time interval styles serve as the basis for generating the total-station one-time topology connection graph, the total-station topology connection graph can be formed only by a small amount of topology connection operation, manual intervention is reduced on the premise of guaranteeing one-time topology connection accuracy, and working efficiency is improved.

Description

technical field [0001] The invention relates to a method and a device for generating a primary topology connection graph of an intelligent substation, and belongs to the technical field of comprehensive automation of an intelligent substation in a power system. Background technique [0002] With the promotion of smart substations, the primary system topology model as the basic model of the substation has been increasingly valued by the main station side and the plant side, and higher requirements have been put forward for the standardization of the primary topology model. [0003] In the application of substation engineering, the generation of the topology model of the substation primary system usually needs to go through two stages: the drawing of the topology connection diagram and the generation of the topology model. The drawing of topological connection graph is the basis of model generation, and the drawing quality of topological connection graph will directly affect t...
