Embodiment Construction

[0039] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] A method and tool for automatically checking the correctness of a secondary virtual circuit in an SCD file, the method comprising the following steps:

[0041] Step 1. This tool selects the SCD file to be checked for the correctness of the secondary virtual circuit, analyzes it, and displays the secondary equipment list, IED instance configuration, IED virtual terminal connection relationship, etc. in a graphical interface, and at the same time obtains the contents of the SCD file , stored locally in json text format.

[0042] Step 2. The tool is designed with a dedicated interface channel to obtain the SCD information in the json text, and store the information in the memory of the inspection tool for real-time SCD correctness inspection and analysis.

[0043] Step 3. The tool checks the correctness of the secondary virtual circuit...

Abstract

The invention relates to a method and a tool for automatically checking correctness of a secondary virtual loop of an SCD file, and belongs to the field of power grids. According to the method, SCD analysis can be carried out, and correctness inspection can be carried out on the secondary virtual loop of the SCD file. By analyzing the SCD file, information is displayed according to categories in graphical forms such as graphs, tables and the like, such as secondary equipment tables, IED instance configurations, communication configuration information, GOOSE / SV configurations and IED virtual terminal connection relationships, so that a convenient and visual viewing means is provided for on-site analysis. In addition, after the SCD is analyzed, the content of the SCD file can be stored locally in a json text format, a special interface is designed, text information is obtained and stored in an inspection tool memory, real-time SCD correctness inspection and analysis are carried out, andan analysis result is displayed.

Description

technical field [0001] The invention belongs to the field of power grids, and relates to a method and a tool for automatically checking the correctness of a secondary virtual circuit of an SCD file. Background technique [0002] SCD is the abbreviation of substation configuration description in the substation IEC61850 standard, that is, the system configuration file of the whole station. With the rapid development of smart substation technology, smart substation has entered the stage of large-scale practical use. Compared with conventional substations, the secondary circuit of smart substations has changed from cable connection to optical fiber connection, and the secondary cable circuit has become a "virtual circuit". The design, commissioning and operation and maintenance methods of smart substations have undergone major changes. As the core configuration file of smart substation SCD, the secondary virtual circuit includes the sampling circuit and the circuit breaker trip...
