Embodiment
For ease of the understanding of the present invention, first brief description is carried out to the relational language used in execution mode below.
SCD file: the abbreviation of Substation Configuration Description, represents substation configuration description file, the configuration information of integrated whole transformer station.
IED equipment: the abbreviation of Intelligent Electronic Device, represents intelligent electronic device.Comprise one or more processor, the data from external source can be received, or externally send data, or carry out the device that controls.
ICD file: the abbreviation of IED Capability Description, represents IED capacity of equipment description document.
CID file: the abbreviation of Configured IED Description, represents configuration IED device description file, stores the configuration information needed for the operation of IED equipment.
CRC code: the abbreviation of Cyclic Redundancy Check, represents cyclic redundancy check (CRC) code, whether is unanimously usually used in analyzing content of text.
Fig. 1 is the applied environment Organization Chart of the better embodiment of the network analysis system that SCD of the present invention checks online.The network analysis system 100 that this SCD checks online is applied in the network analyzing apparatus 10 that SCD checks online, in present embodiment, the network analyzing apparatus 10 that this SCD checks online comprises processor (CPU) 11, memory 12, display 13, mainboard 14, keyboard 15, mouse 16, optical-electrical converter 17, output device 18.The network analyzing apparatus 10 that this SCD checks online, by the heartbeat message of the multiple IED equipment 20 of network reception, connects SCD configuration tool 30 by network simultaneously and downloads SCD file.
SCD file is that the configuration of all IED equipment 20 of whole transformer station becomes file with the general collection that substation network configures.Need the IED capacity of equipment description document (ICD) first importing full station during field conduct, then configure the network information of all IED equipment 20, form original SCD version by SCD configuration tool 30.
Again consult Fig. 1, the initialization procedure of IED equipment 20 is: imported to by ICD file in SCD configuration tool 30, generate SCD file after configuration, the key message of each IED equipment 20 is verified simultaneously, generate the 2nd corresponding CRC code and be stored in SCD file; Being extracted the IED device core information (comprising the 2nd CRC code generated) in SCD file by IED configuration tool 40, is then the CID configuration file of correspondence that each IED equipment 20 generates, and under install in corresponding IED equipment 20.In present embodiment, this CID configuration file comprises the CRC code generated according to the 2nd CRC code.
Under normal workflow, a CRC code because of CID comes from the 2nd CRC code of SCD file, then a CRC code of IED equipment 20 and SCD the 2nd CRC code of network analyzing apparatus 10 of checking online is completely equal, but because lower dress SCD file and lower dress CID file are two different operations, and also through human configuration between two different operatings, therefore may cause CID file and the not corresponding problem of former SCD file, need when substation operation to be verified by further method.
The network analysis system 100 that the operating system that this processor 11 carries for the network analyzing apparatus 10 performing this SCD and check online, this SCD check online and all kinds of software that Qi Nei installs and application program etc.This memory 12 can be internal memory, hard disk, or the storage card of other types or memory device.This memory 12 is for storing Various types of data.This display 13 is for showing all kinds of visualized data and user interface (UI).
