Fuzzy diagnosis method for electro-hydraulic regulating system of hydro-generating unit
Shuming Li · Water Resources and Hydropower Engineering · 2006
So far as the diagnosis on the failures of the electro-hydraulic regulating system is concerned, the membership functions of different parts of the system are obtained with the application of the fuzzy mathematics theory based on both the operation mechanism and operation experiences, and then the features of the failures for the system are got on the basis of the functions as well. At last, the binary tree of the possible maximum failure is made according to the calculated information from the features of the failures, by which the sources of the failures concerned are determined.
