Embodiment Construction

[0036] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] An embodiment of an automatic connection method for a virtual terminal of a secondary circuit of a smart substation according to the present invention:

[0038] Define each signal in the secondary circuit as a characteristic word with a unique identifier to form a mapping table file of the signal and the corresponding characteristic word. The signal referred to here includes the GOOSE internal and external signals of the protection device, the merging unit, and the intelligent terminal. As well as SV internal and external signals, the characteristic words of these signals are the unique identifiers for distinguishing these signals from each other. The format of the characteristic words is Chinese character strings, English character strings, or Chinese character strings and English character strings The combination of characters, the ...

Abstract

The invention relates to an automatic line-connecting method and apparatus for a virtual terminal of a secondary loop of an intelligent substation. An interval line-connecting template with character word information is established; by performing comparison between the character word of the interval line-connecting template and two obtained character word mapping tables, a reference with an SV or GOOSE external signal of the character word in one character word mapping table, and the other reference with an SV or GOOSE internal signal of the character word in the other character word mapping table are found; and the two references are connected so as to form the virtual terminal connecting line. According to the automatic line-connecting method and apparatus, virtual terminals in an interval layer apparatus and a process layer apparatus are automatically correlated in an information configuration process according to the character word in the interval line-connecting template and the two mapping tables with the character word, and configuration of the virtual terminals in an SCD file by the conventional manpower way is replaced, so that automatic configuration is realized, a troublesome connecting process of a secondary virtual terminal line connection is simplified, workload of system configuration is reduced, working efficiency of a construction process of the virtual secondary loop is improved, and the working period is shortened.

Description

technical field [0001] The invention belongs to the technical field of relay protection of intelligent substations, in particular to a method and device for automatic connection of virtual terminals of secondary circuits of intelligent substations. Background technique [0002] The secondary circuit and secondary circuit terminal cable connection design of traditional substations is usually realized by AutoCAD tools, and the construction personnel carry out the on-site secondary cable connection construction according to the design drawings. Compared with conventional substations, the smart substation has many advantages in the secondary circuit. Compared with the traditional substation, the secondary circuit of the smart substation and the terminal connection in the secondary circuit have undergone great changes. The digital virtual circuit of the smart substation has replaced the traditional substation. The physical secondary circuit, the virtual terminal of the secondary ...
