Embodiment
The online proofreading method and the system of relay protection constant value of the present invention; Earlier the parameter of relay protection constant value list and protective device is mated; Again the definite value in the relay protection constant value list after the coupling and the on-the-spot definite value of protective device are proofreaded, thereby realize the purpose that automatic on-line is proofreaded.Below in conjunction with accompanying drawing and the present invention of embodiment illustrated in detail.
The online proofreading method of a kind of relay protection constant value of the present invention, as shown in Figure 1, comprise step:
Step S1, read and resolve the relay protection constant value list from safety three districts;
Step S2, said relay protection constant value list is sent to safety one district from safety three districts, and below safety one district carries out, operates:
Step S3, said relay protection constant value list is generated the secondary device model;
Step S4, the secondary device model and the primary equipment model that generate are shone upon;
Step S5, model after the mapping and secondary model and protective device are carried out parameter matching;
The on-the-spot value data of step S6, calling protective device according to said parameter matching result, is proofreaded the on-the-spot definite value of protective device and the definite value in the said relay protection constant value list.
The relay protection constant value list belongs to management data; Therefore place electrical network production system safety three districts; The data of protective device then belong to power grid control safety one district; In order to realize the online in real time check and correction, must the relay protection constant value single-pass be crossed reverse physical isolation and be synchronized to safety one district, and generate the secondary device model.
To different needs, power department has disposed various information system, like dispatch automated system, electrical power distribution automatization system, information management system, comprehensive automation system of transformer substation etc.In order to accomplish information sharing, these systems all follow IEC61970 or IEC61850 international standard, but the object that these two standards are suitable for is different.Dispatching automation adopts the IEC61970 standard, and the smart machine of comprehensive automation system of transformer substation then adopts the IEC61850 standard, and there is the problem of model mapping and coupling in the system of two standards of employing.
One of core of protection definite value check and correction is exactly model mapping and model parameter coupling.After the present invention generates the secondary device model with the relay protection constant value list; Carry out the mapping of secondary device model and primary equipment model; Again the parameter of first and second device model and protective device is mated; Comprising transformer station, primary equipment and protective device type, software version, definite value title or the like, purpose is to make various device object and parameter corresponding one by one, the intelligent matching process that adopts accurately and merge based on the keyword fuzzy matching.Each matching result is preserved automatically, can seek the matching result of last time when mating once more automatically, has avoided the duplication of labour of coupling once more.Protect the automatic verification of definite value at last, the definite value in the fixed value list is proofreaded with the field device definite value, preserve collation, for inquiry.
Owing to pay much attention to and long-term endeavour; The protection definite value information of power department is standard comparatively all, and the definite value title of some fixed value list and the definite value title of protective device are consistent, can adopt the method for accurate coupling; For not satisfying accurate information matching, adopt fuzzy intelligent matching process.Accurately coupling adopts the specialized designs matching process, and it is fast to have speed, the characteristics of algorithm simple and clear; The intelligent matching algorithm of string is then adopted in fuzzy matching.
Various models and parameter after the correspondence, are then proofreaded supplemental characteristic one by one, promptly the on-the-spot definite value of protective device and the definite value in the said relay protection constant value list are proofreaded, and collation can be published to safety three districts.
As a preferred embodiment, the information of relay protection constant value list and secondary device model comprises numbering and title, definite value title, definite value, unit, current transformer and voltage transformer no-load voltage ratio, software version of the device type of protective device, primary equipment or the like.
The online critique system of relay protection constant value of the present invention is the system corresponding with said method, and is as shown in Figure 2, comprising:
The fixed value list acquisition module is used for reading and resolve the relay protection constant value list from safety three districts;
Reverse delivery module is used for said relay protection constant value list is sent to safety one district from safety three districts;
Secondary device model generation module is used for said relay protection constant value list is generated the secondary device model;
The model mapping block is used for the secondary device model and the primary equipment model that generate are shone upon;
The Model Matching module is used for model after the mapping and secondary model and protective device are carried out parameter matching;
Definite value is proofreaded module, is used to call the on-the-spot value data of protective device, according to said parameter matching result, the on-the-spot definite value of protective device and the definite value in the said relay protection constant value list is proofreaded.
Can know by Fig. 2, but above-mentioned module links to each other successively.Wherein, the operation of secondary device model generation module, Model Matching module, model mapping block, definite value check and correction module is all carried out in safety one district.
The other technologies characteristic of this device is identical with said method, does not repeat them here.
The online proofreading method of relay protection constant value of the present invention is used in combination with online critique system, can realizes the purpose of relay protection constant value automatic on-line check and correction of the present invention.
The above embodiment has only expressed several kinds of execution modes of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with accompanying claims.
