the number of the control blocks is started from 1, and the SVin, Gin and Gout control blocks are independently numbered; the channel number is the sequential number of the channel under the control block and starts from 1; tester channel ID, for the SVin control block, the delay channel is named DelayTRtg, and the voltage current channel ID corresponds to Ia1, Ib1, Ic1, Ua1, Ub1, Uc1, Ia2, Ib2, Ic2, Ua2, Ub2, Uc2, Ia3, Ib3, Ic3, Ua3, Ub3, Uc3, Ia4, Ib4, Ic4, Ua4, Ub4, Uc 4; gin control block channel IDs correspond to Bin1, Bin2, Bin3, Bin4, Bin5, Bin6, Bin7, Bin8, respectively; the Gout control block channel IDs correspond to Bout1, Bout2, Bout3, Bout4, Bout5, Bout6, Bout7, and Bout8, respectively.
The intelligent generation process of the standard model file is as follows:
the model file name is the same as the configuration file name, the extension names are different, different test functions correspond to different test function data sets, and the generation of the data sets in the standard model file is mainly divided into 3 types:
1) for a data set irrelevant to a control block in actual tester configuration, a fixed generation mode is adopted;
2) for a data set related to the actual tester configuration control block part, a semi-dynamic generation mode is adopted, a fixed generation mode is adopted for part of data in the data set, and a dynamic generation mode is adopted for the part related to the control block;
3) a full-automatic generation mode is adopted for a data set completely related to the actual tester configuration control block;
the second step is that: development digital tester check template
1) Adding a communication command test item for downloading a configuration file of the detection device, wherein the communication command parameter is a sub-configuration file ID in the configuration file of the tester;
2) adding a testing functional electric quantity testing item of 'tester configuration' for setting the voltage-current transformation ratio output by the tester;
3) adding an 'IEC 61850 configuration' test function electric quantity test item for setting download of a configuration file of the digital tester;
4) adding a 'start recording' communication command test item, and recording by using a start detection device;
5) adding a 'voltage current test' test function electric quantity test item for controlling the digital tester to output voltage and current with fixed values according to test requirements, wherein a 'read measurement value' communication command sub item is added to the test item for acquiring the currently measured voltage and current values output by the digital tester;
6) adding a 'stop recording' communication command test item to stop the recording of the detection device;
the third step: creating automatic detection task for automatic detection
1) Loading a calibration template of a digital tester and testing and compiling a model file of the tester;
2) selecting different tester interface modules according to tester manufacturers, and selecting a semi-automatic test interface for a digital tester which is not developed and corresponds to a tester interface;
and starting an automatic detection process, and controlling the tester interface module and the detection device interface module to finish automatic detection by the automatic detection module according to the detection process in the verification template, and automatically generating a detection report.
