Collaborative Design Method of Secondary Virtual Circuit Graph Based on Standardized Virtual Terminals

Abstract

The invention particularly relates to a design method for combining files with figures at virtual terminals in an intelligent substation. The design method comprises the steps that a digital substation is divided into a plurality of function areas according to functions by taking the digital substation as a main body; the types of IED equipment required by the function areas are determined according to the function requirements of the function areas; the required virtual terminals are determined according to the logical relationship among IED equipment; the corresponding input virtual terminals and output virtual terminals are connected to form a virtual terminal connecting figure according to the logical connecting relationship among the IED equipment; logical associations of the IED equipment are expressed through the physical relations of the IED equipment, wherein the virtual terminals are described through virtual terminal names and virtual terminal numbers; a virtual terminal connecting chart of the IED equipment is established according to the virtual terminals connected with the IED equipment. Virtual terminal visual display is provided for construction units, owner units, operating maintenance units and equipment integrators, the work efficiency is improved, and the risk that the virtual terminals are wrongly configured is reduced.

Description

technical field [0001] The invention is a novel virtual terminal design method of an intelligent substation system, and specifically relates to an expression method for combining files and graphics of an intelligent substation virtual terminal. Background technique [0002] The configuration file (System Configuration Description, SCD) that reflects the configuration information of the smart substation system is mainly composed of virtual terminal instance configuration, communication parameters, communication configuration between intelligent electronic devices (Intelligent Electronic Devices, IED), and substation primary system structure information. [0003] The virtual terminal instantiation, that is, the virtual terminal connection between smart devices, is one of the important steps in configuring the SCD file. At present, there are two ways to express the virtual terminals of smart substations. One is the virtual terminal connection diagram designed by using AutoCAD t...

Problems solved by technology

The virtual terminal is an abstract concept. The construction, commissioning and operation maintenance personnel cannot intuitively query the output of the IED virtual terminal and where it is connected. They can only inquire whether there is an output of the IED virtual terminal in the associated IED virtual terminal. This method is time-consuming and labor-intensive; and due to the large number of virtual terminals, construction and commissioning personnel and operation and maintenance personnel cannot quickly query the required virtual terminals
