Abstract

The invention relates to a method for determining the connection correctness of virtual terminals of an intelligent transformer station. The method forms two virtual terminal relation tables by using a standard virtual terminal relation table format and importing a virtual terminal relation table into a SCD model file, and compares the input correctness of external short addresses by means of a character comparison way. The method may realize automatic comparison of the information in a SCD file, effectively avoids erroneous manual virtual terminal connection, and remarkably improves the debugging efficiency of the intelligent transformer station.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, and specifically relates to a method for judging the correctness of virtual terminal connection in an intelligent substation, which is mainly used in the debugging, maintenance, transformation, expansion process of the intelligent substation, virtual loop transmission and verification. Background technique [0002] Smart substations use digital quantities to transmit sampling value information and switch quantity information. The original hard-wired secondary loop wiring form is replaced by optical fiber transmission of digital quantities. The existing secondary loops rely on virtual loop technology to achieve connections. The connection of the virtual circuit is realized by the connection of the virtual terminal. The connection of the virtual terminal is issued by the design institute in the form of the contact list of the virtual terminal before debugging, and then ...
