However when load on generator varies there will be corresponding variation of load on turbine also if the I/P to the turbine remains same, the speed of the turbine tends to increase or decrease depending on whether there is decrease or increase in load. This will cause speed of generator also vary. In order to maintain constant speed, the steam flow through turbine need to be regulated.Such an operation of speed regulation is known as GOVERNING.It is done automatically by means of Governor. All TG sets have got Hydraulic Governor.ELEMENTS OF SPEED GOVERNER PILOT BLOCK LOAD/SPEED CONTROL PILOT VALVEFOLLOW-PILOT VALVESUMMATION PILOT VALVESPEED GOVERNERINTERMEDIATE-PILOT VALVE) CONTROL VALVE SERVOMOTOR 7) DIFFERENTIATOR (ANTICIPATORY GEAR) 8) LOAD LIMITER9)ELECTROHYDRAULIC TRANSDUCER (EHT)10) CONTROL VALVE SERVOMOTORELEMENTS OF PROTECTION SYSTEM
