GOOSE virtual secondary circuit patterning method of intelligent substation

Abstract

The invention discloses a GOOSE virtual secondary circuit patterning method of an intelligent substation. The method takes an SCD file as the basis, shows GOOSE information, which is numerous and connection relationships of which are complex, in the file out in a diagram manner according to a concept of a traditional relay protection secondary circuit, and establishes a virtual connection diagram through GOOSE input and output information. The virtual connection diagram is provided with enough optical interfaces, GOOSE information of A and B networks in high, medium and low voltage grades of the substation can be accessed one time, and GOOSE optical interfaces between the A and B networks in the various voltage grades are physically isolated and do not influence each other. The method is advantageous in that working efficiency of debugging and working efficiency of operation maintenance are greatly improved, potential safety hazards are eliminated, power supply reliability is guaranteed, and the levels of related technical staff and the operation management level of the intelligent substation are improved.

Description

technical field [0001] The present invention relates to the technical field of the substation field, and more specifically relates to the technical field of the intelligent substation field. Background technique [0002] The smart substation is built on the IEC61850 architecture, based on a high-speed network communication platform, and realizes information sharing and interoperability between devices by standardizing digital information models and transmission. The data of the smart substation is transmitted through the network. Compared with the secondary system of the traditional substation, the analog signal and cable connection are transformed into digital signal and optical fiber connection, so as to realize the relay protection, monitoring and measurement functions of the substation. [0003] The general object-oriented substation event GOOSE is a mechanism used in the IEC61850 standard to meet the needs of fast transmission of substation automation system messages. T...

AI Technical Summary

Problems solved by technology

The intelligent substation realizes the information interaction between the protection devices according to the GOOSE method, including the tripping and closing commands of the protection and the interlocking signal between the compartments, etc., so that the original traditional terminals and terminal blocks disappear, and the secondary circuit of the protection It does not exist, and it is replaced by digital signals based on network and optical fiber transmission. The existence of this difference makes it difficult for the commissioning and operation and maintenance personnel of smart substations based on the existing knowledge structure, which also causes smart substations. The embarrassing situation in the construction of substations. Compared with traditional stations, the commissioning and maintenance of the secondary system is more complicated, the work efficiency is lower, and the requirements for operation and maintenance personnel are higher. With the increase in the number of smart substations put into operation, the commissioning and maintenance of new substations Maintenance problems of commissioned substations will become increasingly prominent
