Problems solved by technology

However, SCD files are often huge in size, up to hundreds of MB, and the speed of fully loading the file is slow, and there are disadvantages such as low visibility during configuration, slow configuration speed, and inability to configure in parallel.
The current SCD configuration software adopts single-person manual configuration, which solves the problem of low visibility to a certain extent, but the problem of not being able to be configured by multiple people at the same time still exists

Embodiment 1

[0036] refer to figure 1 As shown, the present invention is based on the SCD file online parallel configuration system of the database interface layer operation flow, and the online configuration group includes a host server connected by a local area network and a plurality of configuration slaves;

[0037] Set the file layer and database layer on the host server, the file layer stores the SCD file to be configured, the host server analyzes the SCD file with configuration, obtains the IED device data and communication subnet data corresponding to the IED model, and stores them in the database layer;

[0038] The application layer is set on each configuration slave to provide users with a configuration interface for SCD file configuration, and the user sends configuration commands through the configuration interface, and the user configuration commands include operation types and configuration parameters;

[0039] The host server and the configuration slave are connect...

Embodiment 2

[0048] refer to Figure 6 As shown, a method for online parallel configuration of SCD files based on database interface layer operation flow, including steps:

[0049] S1, load the SCD file to be configured, and store it;

[0050] S2, analyzing the SCD file, obtaining data related to each IED object model, and generating an IED device database and a communication subnet database;

[0051] S3, obtaining the configuration commands sent by the user, sorting the operation queue according to the order in which the user configuration commands are issued, and then performing configuration operations on the data in the IED database according to the operation type and configuration parameters of each user configuration command in the operation queue;

[0052] S4, updating the SCD file to be configured according to the real-time data in the IED equipment database and the communication subnetwork database at intervals of a set time.

[0053] In step S1, the loading method ...

Embodiment 3

[0056] refer to figure 2 The schematic diagram of the SCD file configuration process shown in the figure, after opening the SCD file stored in the file layer, it is analyzed to obtain the IED device model and communication subnet, and then the IED device model and communication subnet are established with the database entries stored in the database layer Mapping to get the substation secondary IED equipment database and communication subnet database. The communication subnet database includes three subnets of SV, GOOSE, and MMS. After dualization, there are six communication subnet databases in total. The entry information of each database before configuration is incomplete, and what is missing is the configuration information. During the configuration process, the configuration information is written through the interface layer function, and these entries are modified to form a complete IED device database and communication subnet database, that is, a complete substation...

Abstract

The invention discloses an online parallel configuration system and method based on database interface layer operation flow and used for SCD (substation configuration description) files. When the system and the method are applied, SCD files of the whole station are analyzed firstly, IED (intelligent electronic device) models and communication subnets are mapped into an IED database and a communication subnet database, an interface layer is established on a database layer, an interface function is set, a configuration operation interface is arranged on an application layer, so that a user can input configuration commands and configuration parameters through the configuration operation interface, the databases are accessed and modified through the interface function provided by the database interface layer, and the SCD files are configured on the basis of the mapping relation between the databases and the SCD files. During parallel configuration, modification of IED files by the user is processed sequentially in an operation flow manner, data in the databases is modified one by one, and a modification result is returned to a configuration slave through the interface function. With adoption of the system and the method, collaborative configuration of the SCD files by multiple users can be realized, configuration conflict is avoided, configuration efficiency is increased, and configuration errors can be reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent substation data processing, in particular to an online parallel configuration system and method for SCD files based on database interface layer operation flow. Background technique [0002] In a smart substation, the information interaction of various types of intelligent electronic devices (IEDs) depends on the substation configuration description file (SCD). The SCD file is unique in the whole station, contains all the information in the station, describes the instance configuration and communication parameters of all IEDs and the communication configuration between IEDs. However, SCD files are often huge in size, up to hundreds of MB, and the speed of fully loading the file is slow, and there are disadvantages such as low visibility during configuration, slow configuration speed, and inability to configure in parallel. The current SCD configuration software uses manual configuration by one...
