Study on Dynamic Alarm Curve of Condition Monitoring Parameters of Hydropower Unit

The hydropower condition monitoring alarm value ere studied in the paper, due to the change of operation conditions, the monitoring parameters of the unit had a huge impact, if the alarm value was too small, the hydropower alarm value cannot achieve full condition; if the alarm value is too big then it had no use in the good condition, In this article, A dynamic alarm curve model is proposed, take the head cover vertical vibration as an example, establish dynamic alarm curve model, GA-BP neural network model was established, the head cover vertical vibration is obtained by training and output dynamic curve of alarm.
