Method for detecting position state of valve element of emergency distributing valve of hydraulic turbine unit speed regulator

The invention discloses a hydraulic turbine unit governor accident distributing valve core position state detection method. The method comprises the following steps: step 1, sampling distributing valve core position state data; 2, data preprocessing; step 3, feature coding; step 4, obtaining reconstructed sample features; step 5, model training; step 6, classification detection; step 7, system development; according to the method, through the feature coding of the distributing valve sample and the construction of the reconstruction model, several loss functions such as coding and decoding discriminators are respectively set for mutual restriction, so that the optimal effect is achieved; according to the coding of input sample features, the transformation of sample data is realized by adopting deconvolution operation, the nonlinearity of state sample data is increased, the robustness of model performance is increased, and the influence of noise labels on model training is effectively reduced. 本发明公开一种水轮机组调速器事故配
