Abstract: 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.

Key words: magnetic stripe encoder, unit creep, creep monitoring device
