Index display method and system for IED messages of intelligent substation

Abstract

The invention discloses an index display method and system for IED messages of an intelligent substation, and the method comprises the steps: analyzing SCD file collection message feature informationto form a mapping dictionary, traversing message file collection message classification feature information to form a message classification index, constructing an annular cache space of a message, and preloading message detailed information dynamically analyzed by a background thread; and realizing index display of brief information and detailed information of the messages according to the classification of the messages. The message information can be visually and quickly browsed and displayed, and when a user browses brief message information, the background thread performs dynamic analysisand preloading, so that the memory space is remarkably saved, and the operation efficiency is improved. By reasonably setting the number of messages dynamically analyzed by the background thread, thephenomena of delay, blockage and the like of a display interface are avoided. And for personnel performing debugging or detection on the engineering site, the dependence on the IEC61850 standard and other related regulation specifications is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the application field of electric power engineering, and more specifically relates to an index display method and system for intelligent substation IED messages. Background technique [0002] The IEC61850 standard is the only global common standard in the field of power system automation, which realizes the standardization of engineering operation of smart substations and makes the engineering implementation of smart substations standardized, unified and transparent. The Intelligent Electronic Device (IED) in the smart substation uniformly sends and receives messages according to the IEC61850 standard, forming a cooperative communication system among the smart devices. In the project, when debugging and configuring the smart device, in order to avoid misjudgment or false normal operation of other devices due to the error of the message content, it is necessary to verify whether the communication information of a single smart de...

AI Technical Summary

Problems solved by technology

In a substation environment with many IEDs, when checking the IED modeling information in the message, it is necessary to search in tens or even hundreds of megabytes of SCD files. This operation is quite cumbersome and error-prone

When the equipment is configured and debugged, the devices in the factory station are running continuously. The tracking of some problems needs to record the messages in the long-term copying. At this time, the message files are very large, and the query and browsing will become very difficult. slow
