Intelligent transformer substation communication method capable of modeling on basis of physical port of Ethernet switch

Abstract

The invention provides an intelligent transformer substation communication method capable of modeling on the basis of a physical port of an Ethernet switch. The intelligent transformer substation communication method is characterized by comprising steps: describing an IEC (international electrotechnical commission) 61850 model of the Ethernet switch by the aid of an RDF (resource description framework) in a form identical to that of an IEC61970CIM (common information model), designing a graphic primitive type model of the Ethernet switch in an AutoCAD (auto-computer aided design), and recording a unique identification of each corresponding resource object in the RDF model via an extended attribute in the Ethernet switch and a port graph; and creating one-to-one corresponding mapping relation between each corresponding resource in the model RDF Schema and each of the Ethernet switch and port equipment of the Ethernet switch, and creating connection relation of a port of an intelligent device and a port of the Ethernet switch by means of drawing connecting lines and folding lines in the AutoCAD. The intelligent transformer substation communication method has the advantages that the physical and logical connection relation between the Ethernet switch and the intelligent device is created and is visually displayed in a graphical manner, and accordingly a design of network communication in a designing process is guaranteed.

Description

technical field [0001] The invention relates to the field of power system design, in particular to an intelligent substation communication method based on physical port modeling of an Ethernet switch. Background technique [0002] For the engineering design of the secondary system of the smart substation, the most influential change is: the smart substation replaces the conventional secondary circuit with the communication network, the virtual digital information in the network replaces the physical electrical signal, and the functional information logic of the secondary system The input and output relationship of the signal and the communication network wiring are no longer in one-to-one correspondence, and the traditional secondary circuit form cannot express the functional logic and signal logic in the smart substation. [0003] At present, the main problems faced in the design process of smart substation are: [0004] 1. Since the design unit lacks a complete graphic su...

AI Technical Summary

Problems solved by technology

Introduced the process of establishing the model file of the secondary circuit in the smart substation. One of the most important devices after networking is the Ethernet switch. In the IEC61850 standard, all intelligent devices such as protection devices and smart terminals are modeled. The network switch is not modeled, which greatly affects the accuracy of the design unit to design a reasonable and accurate network communication
