Application of Creep Monitoring Device of Hydropower Unit Based on Magnetic Stripe Encoder
Based on the creeping phenomenon of hydraulic turbine generator set
this paper designs a set of creep monitoring device based on magnetic stripe encoder
which can sense the magnetic stripe through the encoder and send out pulse signals.After the PLC controller collects this pulse signal
it carries out PLC program processing and logic judgment.It can realize the creep signal monitoring of water turbine generator set with high cost performance
high precision and high reliability.At the same time
the protection program after unit creep is designed
to ensure the safe and stable operation of the unit.
