Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing,The present invention is described in further details. At this, exemplary embodiment of the present invention and explanation thereof are used for explaining thisBright, but not as a limitation of the invention.
In prior art, the analysis of string being mended to protection test result adopts: string is mended to the message that protective device generatesThe switching value of receiving with conventional relay-protection tester contrasts, and the action behavior of string being mended to protective device dividesAnalyse, judge the correctness of protection action. Because the analysis of test result is very complicated, mend the tune of protective device for stringExamination personnel, need to be familiar with string and mend function and the principle protected, string are mended to the comparatively difficulty of motion analysis of protective device.For above-mentioned problems of the prior art, the present invention proposes a kind of string and mends protection test result analysis method, deviceAnd system.
Fig. 2 is that the one string that the embodiment of the present invention provides is mended protection test result analysis method flow diagram, as shown in Figure 2,This analytical method comprises:
Step 201: reception string is mended the SOE generating when protective device, according to test current signals, string benefit protection action occursMessage;
Step 202: SOE message is mated with the SOE message prestoring in database;
Step 203: in the time that the match is successful, generate the match is successful test result, determine that string is mended protection action correct; WhenWhen it fails to match, generate it fails to match test result, determine that string is mended protection action incorrect.
Wherein, SOE message (SequenceOfEvents, sequence of events recording), record trouble occur time andThe type of event, during such as certain switch XX, XX divides XX XX second millisecond that fault of what type etc. occurs.
Illustrate below.
In certain test, the SOE message (103 message) obtaining is as shown in table 1, string is mended to protective device and send out103 messages that send are analyzed as follows:
Table 1
Can be learnt by above-mentioned message and analysis thereof, can show string benefit protective device which string benefit has occurred and protected movingDo, string occurs and mend lasting relative time and the time of origin of protection action. Wherein, " B280 " of this symbol (addsWrong, double underline) what represent is a certain defencive function; This symbol " 02 " (adding mistake, single underscore) representsThe a certain action of defencive function.
By above-mentioned course of action is mated with the SOE message prestoring in database, if the match is successful,Generate the match is successful test result, now determine that string is mended protection action correct; If it fails to match, generate coupling and loseLose test result, determine that string benefit protection action is incorrect, can be easy to like this action row of judgement string benefit protective deviceFor correctness.
The comparison procedure of the SOE message prestoring in SOE message and database is as follows:
Still taking certain phase MOV high temperature protection course of action above as example, course of action just just must meet below conditionReally.
1, corresponding phase GAP (forced-triggered is put a gap) trigger command sends, and transmitting time and MOV high temperatureOperating time of protection is poor < 2ms; (ensureing that GAP order normally and in time sends);
2, ABC three-phase breaker co-bit;
3, ABC three-phase breaker divides position, and ABC breaker divides bit time and ABC three-phase breaker co-bit timeThe result of difference mend and heavily throw the error < 10ms of time definite value with string. (heavily throwing is normal to ensure string benefit).
When concrete enforcement, after obtaining test result, can the match is successful test result or it fails to match that test is tiedFruit is shown. Such as, can by the match is successful test result or it fails to match test result is carried out pictorialization displaying.
Based on same inventive concept, in the embodiment of the present invention, also provide a kind of string to mend protection test result analysis device,As described in the following examples. Mend owing to going here and there the principle and string benefit protection survey of protecting test result analysis device to deal with problemsTest result analytical method is similar, therefore ... the enforcement of device can be mended referring to string the reality of protection test result analysis methodExecute, repeat part and repeat no more. Following used, term " unit " or " module " can realize predetermined meritThe software of energy and/or the combination of hardware. Although the described device of following examples is preferably realized with software,Be hardware, or the realization of the combination of software and hardware also may and be conceived.
