A smart substation message simulation test and correlation analysis system and simulation method

Abstract

The invention discloses an intelligent substation message simulation test and association analysis system, and a simulation method. The intelligent substation message simulation test and association analysis system comprises a hardware-in-the-loop simulation system, an information record simulation and analysis system, a SCD (substation configuration description) file parsing module parsing a SCD file, a configuration reading module extracting basic configuration information needed by a related test use case, a template and use case management module for collecting and managing test use cases and standard response templates for the test use cases, and an intelligent device interface simulation module for sending a related message meeting IEC 61850 specifications in a simulation mode. An intelligent test result analysis method based on message response templates is adopted to introduce artificial intelligence to quick result analysis, the message simulation ability of the system is used, a test case is flexibly designed, intelligent organization is carried out, test conditions are realized, and test and analysis efficiency and accuracy are greatly improved.

Description

technical field [0001] The invention relates to a debugging system, in particular to an intelligent substation message simulation test and correlation analysis system and simulation method. Background technique [0002] IEC61850 is the latest "Substation Communication Network and System" series standards formulated by the TC57 working group of the International Electrotechnical Commission to solve the interoperability problems faced by the substation automation system. And the substation automation system, laid the foundation for the "unified standard, unified model, interconnected and open" pattern of power system automation products. 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] The formulation of the IEC61850 standard has been gradually improved since 2000. After nearly ten years of research, study and exploration, ...

Problems solved by technology

[0014] However, the simulation system itself, especially the simulation system mixed with physical IEDs, has only limited data analysis capabilities because it cannot fully record the responses of all the secondary devices involved.

In order to have a panoramic understanding of the response in the entire system, it is usually necessary to supplement it with various recording and analysis instruments including fault recorders, which makes the configuration and coordination of the entire system too complicated and increases the understanding of the results. difficulty of analysis

[0015] 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.
