Description
Technical field
The present invention relates to a kind of methods of calibration about file more particularly to a kind of based on cyclic redundancy check review technology
Configuration file consistency management-control method, belongs to power system automation technology field.
Background technique
Intelligent substation is the key components of smart grid, and the core standard of intelligent substation is IEC61850, and
SCD file is exactly the descriptive file of system configuration of the intelligent substation generated according to IEC61850 standard, and CCD file is used as back
Road exemplary configuration file, this document are only capable of exporting from SCD file.The cyclic redundancy check of virtual terminator configuration includes in SCD file
IED virtual terminator configures cyclic redundancy check and whole station virtual terminator configures cyclic redundancy check, is respectively used to single device configuration management and SCD text
Part configuration management.The consistency for how guaranteeing the configuration information filled under scene and control platform archive file configuration information is real
Now to the key point of control platform core control.In order to guarantee that the configuration information filled under scene and control platform archive file are matched
The consistency of confidence breath takes a variety of key technology means, including configuration file consistency desired result, handheld device detection knot
The methods of fruit, " configuration conformance guaranty " and technological means.
Configuration file consistency desired result refers to circuit exemplary configuration the file information and whole station SCD configuration text in control platform
The consistency of corresponding virtual terminator configuration information in part, main application to technology be CCD file extraction and CCD file
The calculating of cyclic redundancy check.
Handheld device testing result, be by handheld device from control platform download SCD file, imported into handheld device into
Row field-checking, and check results are uploaded into control platform, the purpose is to the configuration information for guaranteeing to fill under scene and control are flat
Archive file accordant configuration information in platform.
" configuration conformance guaranty " is that the verification guarantee property file that SCD file generates is parsed by control platform, in
Appearance includes: intelligent station description information, and device cyclic redundancy check code verifies personal information.The purpose is to guarantee the CRC of field device
Check code is consistent with the cyclic redundancy check in " configuration conformance guaranty ".
Extracting rule about CCD file is as follows:
QGDW 11471-2015 is proposed, in addition to IED is described, FCDA is described, intAddr is described specified in CCD file format,
Remaining descriptive attributes desc, dU element does not extract in CCD file in SCD file.All daughter elements for extracting elements should be with
Sequence consensus in SCD file；All extraction attributes of an element are arranged from the sequence of a-z in alphabetical order；There is no daughter element
It should be using "/> " ending with the element of assignment.
Cyclic redundancy check computation rule about CCD file is as follows:
QGDW 11471-2015 is proposed, should reject desc attribute, IED in CCD file in the sequence for calculating cyclic redundancy check
Attribute of the element in addition to name, GOOSE and SV between attribute of the FCDA element in addition to bType, CRC element, element and belong in subscribing to
Property between space, newline, carriage return character, list symbol, be converted into UTF-8 sequence after retaining the space in element value and attribute value,
Nybble CRC-32 check code is calculated, the nybble CRC-32 check code of calculating is discontented with nybble, and high byte mends 0x0.
The above-mentioned prior art is only capable of realizing the extraction of CCD file and the CRC check of CCD file by tool at present；In
In practical application, it not can guarantee due to artificial origin, mistake caused by being modified to file that is extracted and having verified；
The present invention is the means extracted and verified by automation during file uploads, to guarantee the consistency of configuration file；
Can reduce the cost of desk checking through the invention, improve production efficiency, and can be to avoid being slipped due to personnel caused by
Mistake guarantees the consistency on messaging of configuration file.
