Background technology
At present, substation operation state is realized monitor and detection by dynamic simulation test, and this dynamic simulation test is realized by recording and playback protective device.Dynamic simulation test is dynamic analog test; by simulate various operating conditions and the malfunction of actual transformer station on RTDS; the function of the protection moving in electric system and control device and performance are examined in real time, to guarantee the test of protection and control device reliability service at the scene.
But there are the following problems for existing RTDS recording and playback protection equipment: there is no fixing testing failure exam pool, comparison difficulty; Equipment volume is large, and buying, operating cost is high; Because volume is large, cannot in transformer station, realize relevant dynamic simulation test.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of method of utilizing recording and playback to realize protection equipment test is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of method of utilizing recording and playback to realize protection equipment test, comprises the steps:
(1) typical fault waveform exam pool builds
1) protection is pressed to the logic function classification of IEC61850 regulation;
2) with IED equipment Inspection instrument, be that corresponding typical fault waveform is recorded in each type protection, and manually input the expection action generation test exam pool of corresponding failure waveform;
(2) test process
1) the suitable test exam pool of logic function classifying and selecting of the tested protection of foundation;
2) protection is connected to IED equipment Inspection instrument, and accesses synchronous clock;
3) by the playback of IED equipment Inspection instrument, test exam pool, and receive the action output of tested protection;
4) action that contrasts tested protection is judged test result with the expection action in test exam pool.
As preferably, described typical fault waveform is COMTRADE99 wave format shape file.
Adopt after said structure, beneficial effect of the present invention is:
1, can be by automatically detecting, real-time, can monitor the malfunction of substation equipment.
2, cost is low, convenience is strong, and this protective device volume is little, is easy to carry, and is suitable for the site test of all kinds of transformer stations.
3, use simply, only need recall corresponding exam pool and carry out playback and can test, without building its complicated mould shape, easy operating.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of described method of utilizing recording and playback to realize protection equipment test, comprises the steps: as shown in Figure 1, Figure 2
(1) typical fault waveform exam pool builds
First the typical electric network fault of organizing relay protection expert to face with regard to all kinds of protections carries out taxonomic revision, forms a electric pressure of pressing, the typical electric network fault outline of protection classification of type; Then use RTDS real-timedigital simulation instrument to simulate respectively corresponding fault and record into COMTRADE99 wave format shape file by typical electric network fault outline; Be finally the corresponding action of outputing of the pre-configured protection of each fault waveform, the record of this action is to deposit in exam pool in IEC61850 model mode.
(2) test process
1) according to the suitable test exam pool of logic function classifying and selecting of tested protection, before protection test, should first set the class shape electric pressure of protection, more selected test exercise question is tested;
2) protection is connected to IED equipment Inspection instrument, and accesses synchronous clock, the test macro nominative testing mouth that the fault waveform in exercise question is played back to by test, accesses tested relay protection the test port of this system, receives the fault waveform that this system is sent;
3) by the playback of IED equipment Inspection instrument, test exam pool, and receive the action output of tested protection;
4) action that contrasts tested protection is judged test result with the expection action in test exam pool, the problem existing to evaluate this device, and provide accordingly corresponding test report.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
