Problems solved by technology

[0008] 2. The information display hierarchy of the existing virtual terminal connection visualization method is not enough, and it is difficult to display the connection characteristics and mutual connection characteristics of each voltage level of the entire station
In addition, it is difficult to show the characteristics and connection relationship of the dual configuration for the 220kV part
It is also difficult to reflect the characteristics of the connection relationship between different IEDs
[0009] 3. The existing virtual terminal information connection visualization cannot realize the automatic visual layout based on the whole station
For the display of hundreds of IEDs in the whole station, the connection relationship will be chaotic if the fixed layout method is used, and the connection relationship and connection characteristics of each IED cannot be well reflected

Embodiment 1

[0067] Such as image 3 As shown, an information flow layout method of a smart substation virtual terminal based on an improved force guide algorithm in the present invention includes an SCD file, and also includes the following information flow layout method: S1, analyzing the SCD file; S2, building information flow and network diagrams of the virtual terminal S3, forming node table and branch connection table; S4, performing IED layout according to force-guiding algorithm; S5, automatic layout optimization and adjustment of connection lines.

[0068] Described S1, the analysis of SCD file: adopt existing SCD file analysis tool, can export SCD file and generate Excel file, export each IED table, include IED name and IED description; Each information flow table includes source IED, accepts IED, Type etc.

[0069] The above S2, information flow and network graph modeling of virtual terminals, including the visual display modeling of information flow in the whole station, consi...

Embodiment 2

[0074] This embodiment makes the following further limitations on the basis of Embodiment 1: the specific execution steps in S2 include:

[0075] S21, set attributes for each IED recorded in the SCD file according to the IED device type, voltage level, and manufacturer information; S22, set the attributes for each IED recorded in the SCD file according to the Goose signal, SV signal, and mms signal that represent the connection relationship between IEDs The IED in the set property. For IED nodes, three attributes are mainly considered. First, according to the type of node IED equipment: protection, measurement and control, merging unit, intelligent terminal, and others. Second, it is classified according to voltage level: 110kV, 220kV, 10kV, main transformer node; third, if you get manufacturer information, it can be displayed according to the type of manufacturer, so that you can analyze the connection and cooperation between different manufacturers. For the connection betwe...

Abstract

The invention discloses an intelligent substation virtual terminal information flow layout method based on improved force guiding algorithm, which relates to a multi-source data association analysis,graph data visualization and visualization analysis technology used in the intelligent substation, comprising the following steps: S1, analyzing SCD file; S2, modeling of information flow and networkdiagram of virtual terminal; 3, forming a node table and a branch connection table; S4, carrying out the IED layout according to the force guiding algorithm; S5, performing automatic layout optimization adjustment of connecting lines. The invention can automatically visualize the layout of the IED and the connection relationship of the whole station of the intelligent substation connected by the double bus bars, and the layout speed is fast and the layout is beautiful. The improved force guidance algorithm is used to make the layout more in line with the habits of operation and maintenance personnel, retaining the characteristics of double-bus connection, which can better reflect the various characteristics of information flow of double-bus connection intelligent substation; the method easily reveals the characteristics of IED and related connection relations in the form of double busbar connection, and to find the characteristics of virtual terminal information flow.

Description

technical field [0001] The invention relates to multi-source data association analysis, graph data visualization and visualization analysis technology for smart substations, in particular to an information flow layout method for virtual terminals of smart substations with improved force guide algorithm. Background technique [0002] At present, the visualization of virtual terminal information flow in smart substations mainly focuses on the visualization of IED's own virtual terminal information or interval related virtual terminal information, but the display of virtual terminal connection relationship information flow between IEDs in the whole station is not comprehensive and intuitive. There are many ways to realize the virtual terminal visualization of information flow in smart substation according to different purposes, and the display methods are also different. At the same time, for the visual layout method, the currently adopted method is mainly based on manual layou...
