Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As mentioned above, a method for accurately identifying configuration changes of smart devices mainly includes the following steps:

[0034] Step (1): Start by selecting two versions of the SCD file; the two versions of the SCD file include the latest version of the SCD file and the previous version of the SCD file; respectively compare the three core parts of the two versions of the SCD file ;According to the IEC61850-6SCL standard, the three core parts of the SCD file include the smart device data template part (DataTypeTemplates element), the smart device data model instance and the relationship part (IED element), and the smart device communication part (Communication element); version The comparison work step (2-1) and step (2-2) are carried out synchronously;

[0035] Step (2-1): Compare the smart device data templates of...

Abstract

The invention discloses a method for precisely identifying configuration change of an intelligent device. The method includes selecting two versions of SCD (substation configuration description) files; respectively using an intelligent device data template comparison module, an intelligent device data model example, a correlation comparison module and an intelligent device communication comparison module to compare three core parts of the two versions of SCD files with one another, synchronously performing version comparison; acquiring a LnodeType element list with difference by the intelligent device data template comparison module; operating the intelligent device communication comparison module; acquiring an IED (intelligent electronic device) list with difference in a communication address; and operating the intelligent device data model example and the correlation comparison module to acquire a newly added IED list, an IED list with difference in a data model and an IED list with difference in a data template, merging the acquired IED lists, and figuring out an union to acquire an IED list required to be re-configured. The problem that change of the SCD versions cause re-configuration of the intelligent devices of a whole substation is solved, and work load of joint debugging and debugging of the intelligent substation is reduced greatly.

Description

technical field [0001] The invention relates to a method for accurately identifying configuration changes of intelligent devices. Background technique [0002] Compared with conventional substations, the secondary system of smart substations adopts the latest communication technology and information processing technology. The deployment of functions and the communication relationship between functions must be described and carried by configuration data (in the SCL format of IEC61850). Configuration data is also the core information of common concern in all aspects of the smart grid. The IEC61850 standard recommends an engineering implementation process based on configuration files (that is, SCD files). At present, domestic smart substations are basically implemented according to this mode, that is, using SCD files as an interface to run through the design, joint debugging, commissioning, and acceptance of the secondary system of smart substations. Wait for the construction ...
