Embodiment Construction
[0052] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0053] This application discloses a hydroelectric unit degradation prediction method based on Ensemble Empirical Mode Decomposition (EEMD) and Long Short Term Memory Network (LSTM), such as figure 1 shown, including:
[0054] S101, according to the historical health data of the hydroelectric unit during the non-fault period, construct a characteristic parameter health standard model about the working condition parameters. Specifically, the characteristic parameter health standard model is constructed through the following steps:
[0055] (11) Partition the collected historical health data during the non-fault period according to the preset sub-interval length to obtain multiple sub-intervals; the health data includes working condition parameters and characteristic parameters; working condition parameters include working water head and active power; for examp...
