Graphical generation method of equipment input virtual terminal in smart substation scd

Abstract

The graphical generation method of the input virtual terminal of the equipment in the smart substation SCD first automatically searches for the internal virtual terminal of an IED, and then uses the graphical technology to graphically display the associated internal input virtual terminal and its transmission source information on the interface in partitions and columns , Internal virtual terminal to be associated. Then use graphical drag and drop to specify the corresponding sending virtual terminal for an internal virtual terminal, and form a virtual connection through two-stage submission. Beneficial effects of the present invention: 1) automatically search and display all internal virtual terminals of the local IED; 2) divide and display all internal virtual terminals of the device in upper and lower halves; 3) give and display the information of each input virtual terminal in columns Sending source information, its description and data reference; 4) Quickly and accurately find each sending virtual terminal of a sending IED as a candidate sending virtual terminal of a local IED; 5) Generate or update virtual terminals through graphical drag-and-drop operations and two submissions Connection, the operation process is intuitive and convenient.

Description

technical field [0001] The invention relates to the technical field of commissioning, operation, maintenance, and equipment research and development of intelligent substations, and specifically relates to a graphical generation method for virtual terminal input of equipment in the SCD of an intelligent substation. Background technique [0002] The smart substation based on IEC61850 is an important part of the smart grid. The substation configuration description SCD (System Configuration Description) file reflects the configuration information of the smart substation automation system and describes all instances of intelligent electronic devices (IEDs) in the smart substation. Configuration and communication parameters and other information. At present, the ExtRef node under the Inputs node under the Inputs node of each subordinate node logic device LD (Logic Device) of each IED is usually used to represent the input virtual terminal of each LD. A typical ExtRef node content...

However, this form-based configuration operation is very complicated, and the configuration efficiency is very low, and the information displayed on the internal virtual terminal and input virtual terminal is limited. The input virtual terminal of the

At present, there is no literature that uses graphical display to input virtual terminal detailed information, partition display to associate and to-be-associated internal virtual terminals, and uses graphical drag-and-drop operations to assist in the rapid generation of virtual terminals.
