| Abstract | ||
| This paper will working on the control valve main signal( demand) and the vibration of the steam turbine .will be putting condition to limiting the vibration increase in the turbine and generator, then when resolved the problem caused the turbine or generator vibration the main demand will return to normal value or normal turbine speed . This paper will take the power plant install from the Ansaldo company to work on this type of power plant . In this paper will us three type of circuit,this circuit contain op-amplifier us as comparator and the electronic relay to be isolate the signal in the circuit used and PNP &NPN transistor, by this working can be avoid the damage in turbine or generator result from vibration of the power plant. | ||
