Method for realizing visualization of intelligent substation IEC61850 communication message

Abstract

The invention discloses a method for realizing the visualization of an intelligent substation IEC61850 communication message, and relates to the technical field of IEC61850 communication. At present,service information contained in the communication process cannot be visually displayed to operation and maintenance technicians, and the manual analysis of communication faults and the technical training of communication protocols cannot be efficiently supported. The method comprises the steps of loading and parsing a substation configuration definition file; generating an information model of anIED and an information model of a data object; establishing an association relationship between a data set contained in the IED and the information model of the data object; obtaining an MMS or GOOSEmessage; matching the information model of the IED; generating original packet information of the communication message; generating a service name of the communication message; generating service data information of the communication message; and displaying the service information of the communication message. The method disclosed by the invention improves the readability of the communication message, and solves a problem that the displayed information is too abstract and not conducive to manual reading, understanding and analysis because the traditional network packet analysis software doesnot endow service data semantics to the MMS message and GOOSE.

Description

technical field [0001] The invention relates to the technical field of IEC61850 communication, in particular to a method for realizing the visualization of IEC61850 communication messages in intelligent substations. Background technique [0002] The IEC61850 standard is the latest and most complete communication standard in the field of substation automation. Due to its outstanding performance in improving equipment interoperability, as well as its openness and scalability for future needs, the IEC61850 standard has been recognized worldwide Widely used, it has become one of the core standards in the field of smart substations, including China's smart grid construction. In the substation adopting the IEC61850 standard, various devices in the substation exchange data through the network, and the information transmission method has undergone fundamental changes. In the subsequent accident analysis, the actual application of standards such as the capture and analysis of commun...

Problems solved by technology

This kind of software usually includes the packet analysis of the GOOSE protocol and MMS protocol supporting the IEC61850 standard, and can display the data structure contained in the IEC61850 communication message in a visual way according to the packet standards of the GOOSE protocol and the MMS protocol. The model configuration file of IEC61850 is not read, and the mapping relationship between the object information of IEC61850 and the variables of MMS and GOOSE messages is established. Therefore, the operation and maintenance technicians cannot intuitively follow the information model of IEC61850 when using such tools for message analysis. Understand the business data contained in the communication message, and cannot intuitively understand the main control process according to the control logic defined by IEC61850, such as remote control process, remote adjustment process, etc.

[0004] Another type of tool is a network communication recording and analysis system specially designed for digital substations. In addition to monitoring and recording the network communication process, this type of system also provides the visualization function of communication packet information similar to Wireshark. The system can read the IEC61850 model configuration file, but it is mainly for the purpose of enhancing network analysis. It does not establish a mapping relationship between the business information contained in the model configuration file and the data structure of the communication message. Therefore, the communication process cannot be intuitively The included business information is displayed to the operation and maintenance technicians, which cannot efficiently support the manual analysis of communication faults and the technical training of communication protocols
