Method for rapidly initializing client communication of IEC61850 intelligent device

Abstract

The invention discloses a method for rapidly initializing client communication of an IEC61850 intelligent device. The method comprises the following steps of: analyzing an scd file according to an IEC61850 standard through a guide library subsystem, processing a data object model of an intelligent device model, saving a data object type and a corresponding index to a client communication configuration file, reading the client communication configuration file through the client, establishing and saving a data structure of the data object through the client, finishing initialization of the data object until the processing of all data objects is finished, and finishing the initialization process of the client. Aiming at the problem that the conventional IEC61850 intelligent device client is low in initialization speed in the process of processing lots of data, the trouble that the model needs to be continuously modified and the client needs to be restarted in the processes of mounting and debugging the system, the problem that the data is lost caused by switching of the master and slave intelligent device clients due to various factors in the process of operating the system, and other problems caused by the reason that the restoration of intelligent device and client communication needs to be reinitialized are caused.

Description

technical field [0001] The invention belongs to the field of MMS communication processing between an intelligent device adopting the IEC61850 protocol and a client terminal at the station end, and in particular relates to a method for rapidly initializing the client terminal communication of the IEC61850 intelligent device. Background technique [0002] The International Electrotechnical Commission TC57 formulated the IEC61850 communication standard on the basis of summarizing the previous communication protocols. Through the unified modeling of the objects in the substation automation system, the communication standard adopts object-oriented technology and an object communication service interface independent of the network structure, which enhances the interoperability between devices, and can realize wireless communication between devices of different manufacturers. seam connection. This standard has the characteristics of flexible configuration, high reliability, and st...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem of slow communication initialization speed of the IEC61850 intelligent device client. When digital substations, smart substations, and energy storage stations collect a large number of data object instances, the initialization time of the client using traditional processing methods is particularly long. It makes it difficult to debug the system, and when it is difficult to switch between the active and standby systems, important monitoring data will be lost, and other problems will occur when the communication is interrupted and then restored.
