Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0056] like figure 1 As shown, a method for establishing a virtual-real link mapping relationship in a smart substation includes the following steps:

[0057] Step 1. According to the actual situation of the smart substation, use a system configuration tool (such as NARIConfiguration Tool of Guodian NARI) to complete the system configuration, including configuring the port number and all virtual terminal connections, generate an SCD file, and use the system configuration tool to configure the physical link of the substation Information, generate SPCD file.

[0058] Step 2, extract the physical link in the SPCD file.

[0059] The process of extracting the physical link in the SPCD file is as f...

Abstract

The invention discloses a method and system for establishing a virtual-real link mapping relationship in an intelligent substation. Based on SPCD files and SCD files, the invention obtains physical link information by extracting and numbering independent physical port information in SPCD, and converts physical The link information is extended to the SCD file to establish a mapping relationship with the cable element in the SCD file, and then use the association relationship between the cable element and the virtual link to establish a mapping relationship between virtual and real links, which is convenient for operation and maintenance personnel to implement according to the virtual link. The fault information quickly locates the fault location of the physical link, and provides a feasible method for solving the whole station information visualization of the smart substation.

Description

technical field [0001] The invention relates to a method and system for establishing a virtual-real link mapping relationship in an intelligent substation, belonging to the field of electric power automation. Background technique [0002] The SPCD (Substation Physical Configuration Description) file describes the physical circuit configuration of the whole station, including configuration information such as cells, screen cabinets, optical distribution, optical cables, and fiber cores, and completely represents all physical port information through which signals are transmitted in the intelligent station. Smart substations usually only use SCD (Station System Configuration File) files to describe substation information. SCD mainly describes substation secondary circuit configuration information and device port information, and lacks description of physical link information. When a communication failure occurs on the site of a smart substation, engineers can only determine th...
