A Master-Substation Integrated Information Interaction Intelligent Gateway Machine

Abstract

The present invention relates to a master and sub station integrated information exchange intelligent gateway machine. The master and sub station integrated information exchange intelligent gateway machine is characterized in that the master and sub station integrated information exchange intelligent gateway machine comprises an integrated configuration module, a local communication module, a remote communication module, and a database module; the integrated configuration module carries out data exchange with the local communication module, the remote communication module, and the database module; the local communication module carries out data exchange with the integrated configuration module and the database module; the remote communication module carries out data exchange with the integrated configuration module and the database module; and the database module carries out data exchange with the integrated configuration module, the local communication module, and the remote communication module. The master and sub station integrated information exchange intelligent gateway machine is used as a client to carry out IEC61850 communication with each bay level IED equipment of an intelligent substation and is used as a server to carry out IEC61850 communication with a dispatching master station, the human intervention is not needed, the flexible selection and setting of multiple communication protocols can be realized through configuration, and the integrated maintenance function of an intelligent substation bay level equipment model to a dispatching master station model is realized.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, in particular to a master-substation integrated information interaction intelligent gateway machine. Background technique [0002] With the rapid construction of smart grids and UHV interconnected large grids and the promotion of the State Grid Corporation's "three sets and five majors" strategy, the modern power system has put forward a lot of challenges for the integration, standardization, refinement, adaptability and flexibility of power grid operation control. high demands. The automation technology and level of control centers and smart substations have been significantly improved and advanced. However, the integrated operation management of the interaction between the control center and the substation is far from enough. [0003] The International Electrotechnical Commission has successively formulated IEC61970 and IEC61850 respectively for internal system interc...

AI Technical Summary

Problems solved by technology

[0004] At present, the smart substation gateway mainly focuses on the transmission of real-time data, and mainly uses 101, 104, DL476 and other communication methods to communicate with the dispatching master station, and has less support for IEC 61850 communication between master and sub-stations. The integrated configuration function of the system is relatively weak, especially the integrated configuration from the intelligent substation interval equipment model to the dispatching master station model cannot be realized, and the demand for integrated information interaction between the master and substations cannot be met.
