Integrated simulation adjusting-testing system and simulation adjusting-testing method for intelligent substation

Abstract

The invention discloses an integrated simulation adjusting-testing system for an intelligent substation, comprising a digital physics hybrid simulation system, an information recording and analyzing system and a user operation interface, which are integrated together, and a physical intelligent device according with the IEC61850 (International Electrotechnical Commission) communication protocol is adjusted and tested through a physical network port by utilizing the communication network; the digital physics hybrid simulation system and the information recording and analyzing system share data with the user operation interface, the digital physics hybrid simulation system is communicated with the physical intelligent device via a physical interface to adjust and test the physical intelligent device, the digital physics hybrid simulation system simulates to generate an electrical condition of a power primary system and transmits the information representing the electrical condition to the physical intelligent device as the third party in the form of IEC61850 standard message; and the information recording and analyzing system records the whole information interaction process of the digital physics hybrid simulation system and the physical intelligent system in real time, analyzes the received information in real time and reports the analysis result, and the result is displayed by the user operation interface.

Description

technical field [0001] The invention relates to a simulation commissioning system and a simulation commissioning method, in particular to an integrated intelligent substation simulation commissioning system and a simulation commissioning method for an intelligent substation. Background technique [0002] The formulation of the IEC61850 standard has been gradually improved since 2000. After nearly ten years of research, study and exploration, the intelligent substation established based on this standard is becoming more and more mature, and the construction of intelligent substation will enter a stage of rapid growth. The introduction of the standard makes it possible to exchange information between different manufacturers and different types of smart devices in a standard model through a dedicated data communication network. However, due to differences in the understanding of standards by different manufacturers, communication or intelligent equipment failures, and complex ...

Problems solved by technology

However, this approach makes the configuration and coordination of the entire system too complicated, and increases the difficulty of understanding and analyzing the results.

Moreover, because the above-mentioned recording and analyzing instruments lack the predictive understanding of the meaning of the real electrical information represented by the monitored messages, they can only analyze and interpret the communication status and message format in the station without human intervention. , but cannot really combine the simulation system to conduct an in-depth analysis of the overall site response behavior at the application logic level
