TABLE 1
If the operation parameters are detected not to be in accordance with the preset conditions, the protective shutdown is not caused by the operation under the severe working conditions, is caused by the self factors of the system, can be operated according to the normal shutdown fault reporting, and thus, the timely maintenance when the fault occurs can not be influenced.
And if the operation is judged to be stopped without protection, comparing the operation parameters with the parameters in the special parameter storage library, and judging whether the operation frequency and the frequency change rate need to be corrected according to preset judgment conditions. Here, the determination conditions are: if Tout ∈ (ToutN-2, ToutN + 2); and Tin is an element (TinN-2, TinN + 2); and Fin belongs to (FinN-1, FinN +) 1; and Fout ═ FoutN; and ftm is more than or equal to ftN-5.
