Abstract

The invention relates to a virtual terminal connection imaging method based on a security coding device (SCD) document. The imaging method includes the following steps that a virtual terminal in the SCD document and a virtual terminal connection relation are pre-configured; imaging processing is conducted on the virtual terminal, and the SCD document is imported by using a virtual terminal connection imaging tool; imaging processing results are output and combined to obtain an IED complete virtual terminal drawing. By means of the imaging method, the important virtual terminal connection relation of an intelligent substation is displayed to users visually in a mode easy to read, verification of the intelligent substation is facilitated, and operation and maintaining requirements are met.

Description

Technical field

[0001] The invention relates to the field of auxiliary operation and maintenance of a smart grid, and in particular to a virtual terminal connection graphical method based on SCD files. Background technique

[0002] Beginning in 2005, new technologies, international standards, power company standards, and power industry standards for domestic intelligent substations have all developed in an all-round way. If virtual terminals are used in the design stage, the model implementation follows the GDW396-2009 configuration specification, the process layer networking adopts the point-to-point mode (GDW441-2010), static multicast and dynamic multicast between switches and IEDs, GOOSE and SV for communication between IEDs Technology, intelligent terminals and merging units at the process level, redundant dual network technology at the station control level and process level, etc. These new technologies pose a huge challenge to the operation and maintenance of power compan...
