Research on modeling and application of test signal

Aimed at the problems that the model of test signal was difficult to set and the measurement was hard to achieve in signal-oriented ATS, the way modeling test signal based on STD were introduced and the model of three-phase AC signal which had current limit attribute was built. Furthermore, the principle of intrinsic measurement and generic measurement which would be both used in the later test example was analyzed. At last not only the correctness of the three-phase AC signal model was verified, but also the application of test signals in signal-oriented ATS was showed by the test example.
