Brief description of the drawings

Fig. 1 the present invention is based on the flow chart that IEC61850 replaces the electric power telemechanical device method of testing of service;

Fig. 2 is that IEC61850 replaces service principle realization figure.

Embodiment

As shown in Fig. 1 replaces the electric power telemechanical device method of testing of serving flow chart based on IEC61850, technical solution is described in detail as follows: set up the main website test macro that possesses the IEC61850MMS client that replaces service function by computer software technology, receive the information of sending on the IED equipment of emulation, set up the IED equipment of emulation simultaneously, support to replace service function.IEC61850MMS client is served remote measurement and the remote signalling data value of establishing to emulation IED equipment by replacement, IED analog simulator is accepted the MMS client value of establishing, and support periodicity, data variation, always call together etc. in data and send mode, to delivering to electric power telemechanical device to be measured in substituted data.Compare by the value of sending on the original value to IEC61850 replacement service configuration and electric power telemechanical device to be measured, verify that device to be measured receives and the correctness of forwarding data.

Testing process is mainly divided into following five steps:

(1) main website test macro is set up IEC61850 communication connection to emulation IED equipment, and tested electric power telemechanical device is set up to IEC104 communication connection.The communication connection that tested electric power telemechanical device is also set up IEC61850 with emulation IED equipment.So the data of tested electric power telemechanical device should be consistent with the data of emulation IED equipment corresponding points.

(2) this testing scheme is compared to the data of the data that gather from IEC104 and IEC61850 collection by main website test macro, with correctness and the real-time of verification equipment under test (tested electric power telemechanical device) data processing.

(3) correctness comparison: by data value comparison inspection, owing to may adopting different data transmission formats, data allow to have a less transformed error, by default.

(4) real-time comparison: test by delta data, obtain time difference of new data more with IEC61850 passage and IEC104 passage and obtain the result of the real-time of equipment under test.

(5) output test result, form test report.

For realizing the correctness of test, need the data of comparison automatically to set by this test macro, this programme adopts the substitution value model realization of IEC61850.Be convenient to like this test function and the performance of equipment under test under various value conditions.Fig. 2 is that IEC61850 replaces service principle realization figure, and in the replacement service model of IEC61850, subEna is mainly used in replacing and enables.As this attribute is made as TRUE, the data attribute of the value of representative data example will be set as the same value of the data attribute of storing data instance substitution value always; As this attribute is made as FALSE, the data attribute of the value of representative data example will be based on process values.For different CDC, subEna is used for lower Column Properties:

CDC Data attribute subEna is applied to SPS StVal and subVal, q and subQ DPS StVal and subVal, q and subQ INS StVal and subVal, q and subQ MV InstMag and subMag, q and subQ CMV InstCVal and subCVal, q and subQ SPC StVal and subVal, q and subQ DPC StVal and subVal, q and subQ INC StVal and subVal, q and subQ BSC ValWTr and subVal, q and subQ ISC ValWTr and subVal, q and subQ
