Intelligent substation integrated intelligent unit

Abstract

The invention discloses an integrated intelligent unit of an intelligent substation. The device includes the following eight modules: SMV sampling processing module, GOOSE processing module, station control layer module, state monitoring processing module, main function module, man-machine interface module and power supply module, Open the module. Through the above modules, the present invention integrates the protection, fault recording, measurement and control, measurement, merging unit, intelligent operation box, and state monitoring functions in the intelligent substation, effectively guarantees the safe operation of the primary equipment and the safe operation of the power grid, and reduces the cost of the equipment. Maintenance costs, which are of great significance to the operation of the power grid and the lean management of equipment.

Description

technical field [0001] The invention relates to an integrated intelligent unit of an intelligent substation, which belongs to the technical field of electric engineering. Background technique [0002] As the smart grid construction enters the practical stage, a new smart substation model has gradually formed for the substation as the supporting node of the smart grid, and many new technologies and new equipment related to smart substations have been produced. The specific contents include: [0003] 1. The electronic transformer is used to unify and simplify the acquisition source. In traditional substations, electromagnetic transformers and cables are used as the main information transmission channels, and there are many defects and technical bottlenecks. Electronic transformers essentially solve these problems, and combine units with IEC61850-9-2 And the standard form of IEC60044-8 is transmitted to other intelligent units to further improve the reliability of the second...

AI Technical Summary

Problems solved by technology

[0008] 1. The addition of merging units and intelligent operation box devices will inevitably lead to a very high cost of secondary equipment;

[0009] 2. The IEC6150 standard is used to share information between each device. The data exchange network is relatively complex, and each device needs to carry out information modeling, which increases the amount of system maintenance;

[0010] 3. There must be a certain network delay for information exchange between various devices, which prolongs the fault removal time of protection to a certain extent
