Problems solved by technology

This working mode and expression method solves the problem of how to express the virtual circuit, but because the table display is not intuitive enough, the design efficiency is low
At the same time, due to the inconsistent description of virtual terminals in the configuration files of various manufacturers, similar projects cannot be reused, and it is still necessary to pair them one by one and check their correctness

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] The "State Grid Corporation of China 110(66)kV-750kV Smart Substation General Design" of the smart substation has very detailed records about typical technical solutions. like figure 1 As shown, this program establishes a tree-like loop matching model, and its specific process is as follows:

[0027] First, enter the typical technical solutions in the technical manual into the computer to form a tree loop matching model covering voltage level, interval, interval equipment, information flow and regular expression information from top to bottom. like figure 2 The diagram shows the hierarchical relationship of the tree-like loop matching model from the voltage level to the interval equipment. Since the tree-like loop matching model has many branches, the voltage level of this scheme is shown by taking 220kV as an example, and the typical ...

Abstract

The invention relates to the technical field of the design of a virtual circuit of an intelligent substation, and particularly relates to an automatic connecting method for the virtual circuit of the intelligent substation. The automatic connecting method comprises the following steps: typing a typical technical scheme on a technical manual in a computer, and generating a tree circuit matching model comprising voltage class, interval, interval equipment and information flow; generating a regular expression on the bottom layer of the tree circuit matching model according to the information flow and a configuration file described by a manufacturer on a virtual terminal in the interval equipment; creating an intelligent substation secondary design software according to the project of the intelligent substation; traversing the tree circuit matching model layer by layer by utilizing the intelligent substation secondary design software, matching all the regular expressions and the virtual terminal of the intelligent substation secondary design software, and connecting the successfully matched virtual terminal. The tree circuit matching model digitized by the computer is applied to the intelligent substation secondary design software, the corresponding virtual terminal in the intelligent substation secondary design software is automatically connected according to the matching result of the regular expression, and the design efficiency of the virtual circuit is greatly improved.

Description

technical field [0001] The invention relates to the technical field of intelligent substation virtual circuit design, in particular to a virtual circuit automatic connection method of the intelligent substation. Background technique [0002] The application of intelligent substation merging unit and intelligent terminal realizes the digitalization of sampling and tripping signals. The communication relationship originally completed by cable connection is changed to optical fiber connection, and the link carried by optical fiber is called "virtual loop" vividly. The signals at the sending end and receiving end of a "virtual circuit" are called "virtual terminals". Cable connections in conventional substations are connected through real terminals on the back panel of the device, which can be visually expressed through drawings. The virtual circuit is a digital signal circuit, and the virtual terminal is described by the configuration file of the manufacturer's device. The num...
