To control the initial run up and synchronization of the machine To assist in matching the power generated to that demanded by responding to the network frequency changes. Two governors, electro-hydraulic and hydraulic are incorporated.
Both the governors are connected in parallel.
FUNCTIONS OF THE GOVERNING SYSTEM
Only one governor can be selected at a time through the process of hydraulic minimum selection. The control valve opening depends on secondary oil pressure and there is a definite relationship between the opening of HP control valve and IP control valve.
Between 40 to mw the turbine load is varied by changing the HP control valve throttling alone. HG consists of mechanical arrangement of spring and bellow. Machine speed is measured and indicated as primary oil pressure.

Range of speed control is rpm. HG acts as a back-up to the EHG. Faster response and precise frequency control.
Actual speed of the turbine is measured by using hall probes Range of speed control is wider rpm. Speed regulation Droop can be changed from 2. EHG can be mechanically isolated by closing the secondary oil line from the local.
