Intelligent substation message simulation testing and association message analysis system and method

Abstract

The invention discloses an intelligent substation message simulation testing and association message analysis system and method. The system comprises an SCD (Security Coding Device) file analysis module, a configuration reading module, a template and case management module, an intelligent device interface simulation module, a message recording module and a user interface module, wherein the SCD file analysis module is used for analyzing the configuration descriptive SCD files of a substation; the configuration reading module is used for extracting basic information required by cases of relevant tests; the template and case management module is used for collecting and managing test cases and standard response templates aiming at the test cases; the intelligent device interface simulation module simulates and sends relevant messages accordant with the IEC61850 standard; the message recording module is used for capturing or responding to the sent messages and generated events and alarming; and the user interface module is used for collecting the test cases and the templates and displaying analysis results. According to the invention, artificial intelligence is introduced in rapid analysis on results through a template method, the message simulation capability of the system is used for flexibly designing test cases, intelligently recognizing and realizing test conditions, thus greatly improving the test and analysis efficiency and accuracy.

Description

technical field [0001] The invention relates to an associated message analysis system and method, in particular to an intelligent substation message simulation test and associated message analysis system and method. Background technique [0002] IEC61850 is the latest "Substation Communication Network and System" series standards formulated by the International Electrotechnical Commission TC57 working group to solve the interoperability problems faced by the substation automation system. This standard is supported by most mainstream manufacturers at home and abroad, and has become a global unified information exchange standard in the field of power system substation automation. [0003] In a substation using IEC61850 standard communication, there are usually three types of interactive messages between smart devices: [0004] GOOSE (Generic Object Oriented Substation Events) message, and general object-oriented substation event message. It is mainly used to send status and ...

AI Technical Summary

Problems solved by technology

[0010] At present, it is difficult to verify whether the devices in the entire system communicate with each other according to the association configured in the SCD, and the device communication process and steps are not clear

Taking the intelligent electronic devices widely used in digital / intelligent substations for system protection as an example, the general protection tester tends to establish one-to-one interconnection with the device under test, lacking the configuration information of the entire system, and unable to monitor the overall system Response to recording and inspection

It is difficult to efficiently test the protection, and it is impossible to analyze the linkage interaction process between the various devices in the smart substation

[0011] In the past, the network communication record analysis system and method for IEC61850 substation automation system can only simply and isolatedly judge whether the format of the message conforms to the configuration based on the interpretation of the system configuration, and cannot analyze the business logic of the system under test. Quickly analyze the relationship between messages

At the same time, the previous systems and methods lack the ability to simulate the interface of smart devices, which greatly affects the efficiency and results of testing and analysis.
