Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
It is of the present invention it is a kind of based on three layer patterns intelligent substation void circuit visualization comparison method, this method from
Three device, link and link channel levels, with the top-down comparison that empty circuit is done step-by-step of patterned way.Including as follows
Three steps：
1）First layer based on device void circuit cyclic redundancy check compares：
Such as Fig. 1, the calculating of empty circuit cyclic redundancy check is mainly to the SCD file of input, for all dresses in this document
It puts, is unique empty time of each device generation by extracting all and relevant information in device void circuit, and according to the information
Road cyclic redundancy check；Empty circuit cyclic redundancy check is compared, can quickly compare the empty loop configuration letter of each device
Whether breath changes, and determines changed device.
In this step specifically empty circuit is relatively related generally in the first layer based on device void circuit cyclic redundancy check
The generation of cyclic redundancy check and two steps of comparison of empty circuit cyclic redundancy check.
Wherein, the generation of empty circuit cyclic redundancy check includes following two steps；
Step（1）：It is extracted in units of IED devices and the relevant empty loop configuration information of the IED devices.IED devices
Between the reaction of empty circuit be GOOSE in communication network and SV transmission control information transmission/reception correspondence.And SCD
The product that file is integrated as system configuration contains all system configuration informations of whole station, and GOOSE/ is sent including IED devices
The messaging parameter of SV control information, the acceptable GOOSE/SV message contents for coming from other devices of IED devices etc..It is specific next
Say that can be extracted from SCD file mainly includes GOOSE transmission letters to describe single IED devices void loop configuration information
Breath, GOOSE receive informations, SV send information and SV receive informations.
Step（2）：In step（1）Afterwards using the CRC algorithm generation cyclic redundancy check of 32 as empty loop configuration information
Identifier.First, the IED device void loop configuration information extracted can be expressed in the form of binary stream, binary system
Stream can be the binary data file on one section of internal storage data or disk in computer program, and concrete form can be by computer
Program voluntarily selects.Secondly, 32 CRC generator polynomials that generator polynomial may be selected to be widely used and have been standardized, for example,
X32+x26+x23+...+x2+x+1 or x32+x28+x27+...+x8+x6+1.It is of course also possible to do not provide that CRC generations are more
Item formula, as long as safeguarding that the computer program of check code uses same generator polynomial.Finally, CRC algorithm right and wrong
Often ripe checking algorithm is applied to the 32 of binary data and agreement for CRC generator polynomials in algorithm, you can must be right
The cyclic redundancy check answered, and IED void loop configuration information is identified with this.
The comparison of empty circuit cyclic redundancy check passes through each IED devices generation mark in the SCD file for two different editions
The cyclic redundancy check of its empty loop configuration information, using IED device names as matching keyword, by graphical list mode, and with face
Colour code notes the IED devices of different cyclic redundancy checks, quickly compares the empty changed device of loop configuration information on the whole.
2）The second layer based on device link information compares：
Such as Fig. 2, device link information reflects the information exchanged between device by GOOSE and SV, by step 1）In
Changed device is compared into downlink message, from the situation of change of device interaction angle-determining link.
Link information comparison includes following aspect：Newly-increased link reduces link and link data variation.By with single
IED devices are visual angle, with the link relation of patterned way displaying IED devices and outer device, and pass through patterned symbol mark
The change information of the link of two version apparatus of note.
Here patterned way specifically uses following scheme：
（1）Using the "+" symbol logo link as newly-increased link on respective links figure；
（2）Using the "-" symbol logo link as reduction link on respective links figure；
（3）On respective links figure with "！" the symbol logo link is there are link data variations.
3）Third layer based on link channel information compares：
Such as Fig. 3, the channel data of actual transmissions, is embodied in hair in the link between link channel message reflection device
A pair of of virtual terminator of the side of sending and recipient connect, by step 2）In have data variation link carry out channel information comparison,
Situation of change from virtual terminator interaction angle-determining void circuit.
Link channel comparison includes following aspect：Newly-increased passage reduces passage, channel data variation.By with single chain
Road is visual angle, and the variation of the link channel is shown with graphical forms mode, and marks two versions by patterned symbol
This link channel change information.
Here specific patterned way is as follows：
（1）Using the "+" symbol logo passage as newly-increased passage on respective channel figure；
（2）Using the "-" symbol logo passage as reduction passage on respective channel figure；
（3）On respective channel figure with "！" the symbol logo passage is there are channel data variations.
By the way that the comparative pattern in intelligent substation void circuit is visualized, real time monitoring includes changing the method that the present invention uses
The variation of empty loop configuration information in SCD file caused by including enlarging process, ensures empty loop configuration information to greatest extent
Security, integrality, uniformity, change by manpower to ensure the poorly efficient and fragile present situation of empty loop configuration correctness,
So as to ensure and be promoted intelligent substation safety operation level, put into operation time, mitigation system of shortening system puts into operation pressure, reduces intelligence
Maintenance cost in energy substation life cycle management.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
