Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, right below with reference to embodiment and attached drawing
The present invention is described in further details.Here, exemplary embodiment and its explanation of the invention is used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
In the prior art, to string mend protection test result analysis using: will string mend protective device generate message
The switching value received with conventional relay-protection tester compares, and the action behavior for mending protective device to string is analyzed,
To judge the correctness of protection act.Since the analysis of test result is very complicated, the commissioning staff for mending protective device for string comes
It says, need to be familiar with function and principle that string mends protection, the motion analysis for mending protective device to string is more difficult.For above-mentioned existing
The problem of technology, the present invention propose that a kind of string mends protection test result analysis method, apparatus and system.
Fig. 2 is a kind of string benefit protection test result analysis method flow diagram provided in an embodiment of the present invention, as shown in Fig. 2,
The analysis method includes:
Step 201: receiving string benefit protective device and reported according to the SOE that test current signals occur to generate when string mends protection act
Text；
Step 202: the SOE message prestored in SOE message and database is matched；
Step 203: when successful match, generating successful match test result, it is correct to determine that string mends protection act；Work as matching
When failure, it fails to match test result is generated, it is incorrect to determine that string mends protection act.
Wherein, SOE message (Sequence Of Events, sequence of events recording), the time and thing that record failure occurs
The type of part, for example XX divides XX seconds XX milliseconds of what kind of failures of generation etc. when certain switch XX.
It is exemplified below.
In certain test, obtained SOE message (103 message) mends 103 that protective device is sent as shown in table 1, to string
Message is analyzed as follows:
Table 1
By above-mentioned message and its analysis it is known that having occurred which string benefit protection is moved it can be concluded that going here and there and mending protective device
Make, lasting relative time and time of origin that string mends protection act occurs.Wherein, this symbol " B2 80 " (add it is wrong, double under
Scribing line) what is indicated is a certain defencive function；The a certain of defencive function that this symbol " 02 " (adding wrong, single underscore) indicates moves
Make.
By matching the SOE message prestored in above-mentioned action process and database, if successful match, generate
It is correct to determine that string mends protection act at this time for successful match test result；If it fails to match, generate it fails to match test knot
Fruit determines that string benefit protection act is incorrect, can be easy to the correctness that judgement string mends the action behavior of protective device in this way.
The comparison procedure of the SOE message prestored in SOE message and database is as follows:
Still by taking certain phase MOV high temperature protection action process above as an example, it is just correct that action process must satisfy following condition.
1, corresponding phase GAP (forced-triggered puts a gap) trigger command is sent, and sending time and MOV high temperature protection act
Time difference < 2ms；(guaranteeing that GAP order is normal and sends in time)；
2, ABC three-phase breaker coincidence；
3, ABC three-phase breaker quartile, and the difference of ABC breaker quartile time and ABC three-phase breaker coincidence time
As a result error < the 10ms for throwing time definite value again is mended with string.(guaranteeing that string is mended to throw again normally).
It, can be by successful match test result or it fails to match that test is tied when it is implemented, after obtaining test result
Fruit is shown.For example, successful match test result or it fails to match test result can be carried out pictorialization displaying.
Based on the same inventive concept, a kind of string benefit protection test result analysis device is additionally provided in the embodiment of the present invention,
As described in the following examples.It mends the principle that protection test result analysis device solves the problems, such as due to string and goes here and there and mend protection test knot
Fruit analysis method is similar, and therefore ... the implementation of device may refer to the implementation that string mends protection test result analysis method, repetition
Place repeats no more.Used below, the software and/or hardware of predetermined function may be implemented in term " unit " or " module "
Combination.Although device described in following embodiment is preferably realized with software, the group of hardware or software and hardware
The realization of conjunction is also that may and be contemplated.
Fig. 3 is that a kind of string provided in an embodiment of the present invention mends protection test result analysis apparatus structure schematic diagram, such as Fig. 3 institute
Show,

It protects in test result analysis device.
The string is mended the SOE message that protection test result analysis device is used to prestore in SOE message and database and is carried out
Matching generates successful match test result when successful match, and it is correct to determine that string mends protection act；When it fails to match, generate
It is incorrect to determine that string mends protection act for test result that it fails to match.
Wherein, matching module 302 and test result generation module 303 also may be collectively referred to as SOE message analysis judgment module.
When it is implemented, the output switch parameter channel of the relay-protection tester and the switching value that string mends protective device are defeated
Enter channel connection；
The relay-protection tester is used to that switch tool signal to be sent to the string by output switch parameter channel and mends
Protective device；
The string mends protective device and is used to pass through On-off signal channel reception switch tool signal；According to test electric current letter
Number and switch tool signal string occurs and mends protection act, and generate SOE message.
Furthermore it is also possible to which the switching value that protective device is mended in the On-off signal channel of relay-protection tester and string (is jumped
Lock economize on electricity) output channel connection.
The method flow specifically tested using the system are as follows:
1) by relay-protection tester, string mend protective device and string mend protection test result analysis device as shown in Figure 4 into
Row connection.
2) definite value and soft pressing plate that setting in protection needs to test defencive function are mended in string.
3) mending protection test result analysis device setting in string needs defencive function to be tested, as shown in figure 5, in action row
Debugged defencive function option is chosen for the defencive function subpage frame in the analysis page.
4) it allows relay-protection tester to issue specified electric current and/or switching value, protection is mended to string and is tested.
5) by string go here and there mend protection test result analysis device to string mend protective device issue SOE message carry out receive and
It automatically analyzes, judges that string mends the correctness of protection act, to be automatically performed the result of the action assessment.
Test result analysis method, apparatus and system is protected to carry out string benefit in conclusion mending using string proposed by the present invention
It is raw when mending protective device according to test current signals generation string benefit protection act by that will go here and there when protection test result analysis is
At SOE message and database in the SOE message that prestores matched, when successful match, generate successful match test result,
It is correct to determine that string mends protection act；When it fails to match, it fails to match test result is generated, determines that string is mending protection act not just
Really, it can be easy to the correctness that judgement string mends the action behavior of protective device in this way, the debugging people of protective device is mended for string
