Embodiment

[0030] Embodiment: Taking the virtual secondary circuit as an example, the whole process is further described.

[0031] Such as figure 1 As shown, step (1): establish a standard equipment library

[0032] Step (1-1): Establish a virtual terminal standard library. Table 1 is the virtual terminal standard library. The "A-phase protection voltage Ua1, A-phase protection voltage Ua2, ..." in the table are all standardized virtual terminal descriptions, which will serve as the basis for building standard secondary equipment element. For the description of virtual terminals, refer to "General Equipment 110 (66) ~ 750kV Smart Substation Secondary Equipment of State Grid Corporation of Power Transmission and Transformation Engineering".

[0033] Table 1 virtual terminal standard library

[0034]

[0035] Step (1-2): Establish a standard secondary equipment library. Table 2 is the standard secondary equipment library. In Table 2, "circuit breaker protection" and "measurement an...

Abstract

The invention discloses a designing method for a virtual secondary circuit and an optical fiber loop of a secondary system of an intelligent substation. The designing method comprises the steps of building a standard secondary equipment library, carrying out designing work, namely choosing equipment from the standard secondary equipment library to be configured, establishing virtual secondary circuit connection and optical fiber circuit connection of secondary equipment, collecting factory information, establishing mapping relation, collecting factory equipment models according to determined equipment factories and determined equipment specifications to finish corresponding relation mapping between a virtual terminal of a secondary equipment embodiment and virtual terminals of factory equipment models and corresponding relation mapping between a back plate port of the secondary equipment embodiment and back plate ports of the factory equipment models, and outputting designing results. The designing method effectively removes strong depend on factories, the designing work is carried out in advance, the designing period is shortened, designing change can be flexibly dealt with, and the designing finished product quality is guaranteed.

Description

technical field [0001] The invention relates to a secondary system design of an intelligent substation, in particular to a design method for a virtual secondary circuit and an optical fiber circuit of the secondary system of an intelligent substation. Background technique [0002] By adopting advanced, reliable, integrated and environmentally friendly intelligent primary and secondary equipment, the intelligent substation has realized the digitalization of the whole station information, the networking of the communication platform and the standardization of information sharing. At present, the design of the virtual secondary circuit of the secondary system of the smart substation mainly depends on the ICD configuration file of the secondary equipment of the manufacturer. Due to differences in the understanding and application of the IEC61850 standard among different equipment manufacturers, the problem of multiple changes and iterations of the ICD configuration file occurred...
