Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The visual comparison method in the empty loop of a kind of intelligent substation based on three layer patterns that the present invention relates to, the method from device, link and link channel three aspects, with the top-down comparison progressively realizing empty loop of patterned way.Comprise following three steps:
1) based on the ground floor comparison of device empty loop CRC check code:
As Fig. 1, the calculating of empty loop CRC check code, mainly to the SCD file of input, for devices all in this file, by extracting all information relevant to the empty loop of device, and is that each device generates unique empty loop CRC check code according to this information; Contrast empty loop CRC check code, whether the empty loop configuration information that can compare each device fast changes, and determines the device changed.
Comparison two steps of generation and the empty loop CRC check code relating generally to empty loop CRC check code are compared in this step specifically in the ground floor based on device empty loop CRC check code.
Wherein, the generation of empty loop CRC check code comprises following two steps;
Step (1): extract the empty loop configuration information relevant to this IED device in units of IED device.Empty loop reaction between IED device be the sending/receiving corresponding relation of GOOSE and SV control information transmission in communication network.And SCD file is as the integrated product of system configuration, contain the system configuration information that full station is all, comprise the messaging parameter that IED device sends GOOSE/SV control information, the acceptable GOOSE/SV message content etc. coming from other device of IED device.What can extract from SCD file specifically will comprise GOOSE transmission information, GOOSE reception information, SV transmission information and SV reception information in order to describe the empty loop configuration information spinner of single IED device.
Step (2): adopt the CRC algorithm of 32 to generate the identifier of CRC check code as empty loop configuration information after step (1).First, empty for the IED device extracted loop configuration information can be expressed with the form of binary stream, binary stream can be one section of internal storage data in computer program or the binary data file on disk, and concrete form can be selected voluntarily by computer program.Secondly, generator polynomial can be selected to be widely used and standardized 32 CRC generator polynomials, such as, x32+x26+x23+...+x2+x+1 or x32+x28+x27+...+x8+x6+1.Certainly, also CRC generator polynomial can not be specified, as long as safeguard that the computer program of check code adopts same generator polynomial.Finally, CRC algorithm has been very ripe checking algorithm, by 32 of binary data and agreement for CRC generator polynomial is applied in algorithm, corresponding CRC check code, and identify the empty loop configuration information of IED with this.
The contrast of empty loop CRC check code is by the CRC check code of its empty loop configuration information of IED device generating identification each in the SCD file for two different editions, with IED device name for coupling keyword, by graphical list mode, and the IED device of different CRC check code is marked with color, compare the device that empty loop configuration information changes on the whole fast.
2) based on the second layer comparison of device link information:
As Fig. 2, device link information reflects by the information that GOOSE and SV exchanges between device, by carrying out link information contrast to the device changed in step 1), from the situation of change of device mutual angle determination link.
Link information contrast comprises following aspect: newly-increased link, minimizing link and link data change.By with single IED device for visual angle, show the link relation of IED device and outer device with patterned way, and marked the change information of the link of two version apparatus by patterned symbol.
Here patterned way specifically adopts following scheme:
(1) on respective links figure with this link of "+" symbol logo for newly-increased link;
(2) on respective links figure with this link of "-" symbol logo for reduce link;
(3) on respective links figure with "! " this link of symbol logo for exist link data change.
3) based on the third layer comparison of link channel information:
As Fig. 3, the channel data of actual transmissions in link between link channel message reflection device, be embodied in transmit leg to be connected with a pair empty terminal of recipient, by to step 2) in have the link of data variation to carry out channel information contrast, determine the situation of change in empty loop from the mutual angle of empty terminal.
Link channel contrast comprises following aspect: newly-increased passage, minimizing passage, channel data change.By with single link for visual angle, show the change of described link channel with graphical forms mode, and mark two version chain paths change informations by patterned symbol.
Here concrete patterned way is as follows:
(1) on respective channel figure with this passage of "+" symbol logo for newly-increased passage;
(2) on respective channel figure with this passage of "-" symbol logo for reduce passage;
(3) on respective channel figure with "! " this passage of symbol logo for exist channel data change.
The method that the present invention adopts is passed through visual for the comparative pattern in empty for intelligent substation loop, real-time monitoring comprises the change of empty loop configuration information in the SCD file that reorganization and expansion process causes, ensure the fail safe of empty loop configuration information, integrality, consistency to greatest extent, change and rely on manpower to ensure the empty poor efficiency of loop configuration correctness and the present situation of fragility, thus ensure and promote intelligent substation safety operation level, put into operation time, mitigation system of shortening system puts into operation pressure, reduces the maintenance cost in intelligent substation life cycle management.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
