Problems solved by technology

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.

Embodiment Construction

[0036] The implementation steps of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] The present invention comprises the steps:

[0038] 1. Read and parse an SCD file, obtain the information of each intelligent electronic device IED and its subordinate logic device LD in the SCD, and construct a list of IED objects.

[0039] Among them, the members of each IED object include the IED name, the IED description, the list of LD objects owned by the IED, and so on. The members of each LD object include LD name, LD description, virtual connection object List linked list contained in the LD, send control block object List linked list contained in the LD, logical node LN object List linked list contained in the LD, etc.

[0040]2. Select an IED as the local IED. Search the logical node LN nodes of the LD nodes subordinate to the local IED in the SCD, find several special logical node LNs named GGIO, CSWI, XSWI, XCBR, etc....

Abstract

The invention provides an imaging generation method for an input virtual terminal of an intelligent substation SCD (System Configuration Description). The imaging generation method comprises the following steps: firstly, automatically searching an inner virtual terminal of a certain IED (Intelligent Electronic Device); utilizing an imaging technology to display a related virtual terminal, the input virtual terminal and sending source information thereof, and an inner virtual terminal to be related on an interface in a partition and column graphing manner; applying imaging dragging and dropping to appointing the corresponding input virtual terminal to the inner virtual terminal; submitting in two phases to officially form the input virtual terminal. The imaging generation method has the beneficial effects that (1) all the inner virtual terminals of the local IED are automatically searched and displayed; (2) all the inner virtual terminals of equipment are displayed in upper and lower regions in a partitioning manner; (3) the sending source information of each input virtual terminal and description thereof and data citing are given in columns and displayed; (4) all sending virtual terminals sent by the certain IED can be found rapidly and accurately to be used as standby input virtual terminals of the local IED; (5) the input virtual terminal is generated or updated through dragging and dropping operation and two times of submitting; the operation process is direct and convenient.

Description

Technical field [0001] The invention involves the field of commissioning, operation, maintenance, and equipment R & D technology of smart substation. Specifically, it is a graphical generation method for the device input of the device in the SCD of the SCD of the smart substation. Background technique [0002] The intelligent substation based on IEC61850 is an important part of the smart grid. The transformation station configuration description SCD (System Configuration Description) file reflects the configuration information of the automated system of the smart substation, describing the examples of all smart electronic devices IED (INTELLIGENT ELECTRONICES) in the smart substation in the smart substation.Configuration and communication parameters and other information.At present, each subordinate node logic device LD (logic device) of each IED is usually used in the Extref node under the Inputs node under the Inputs node of each LD to indicate the input of the LD.A typical Ext...
