Mainly hydraulic turbines are used to drive the electrical alternators which require maintaining the peripheral speed constant even at part load conditions to avoid the change in frequency of electric power. The governing of the hydraulic turbine is done by
  • a)
    controlling the flow area
  • b)
    controlling the velocity
  • c)
    using the fly wheel
  • d)
    combined control of flow area and velocity
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Mainly hydraulic turbines are used to drive the electrical alternator...
As the turbines are required to run at a constant speed (because they are attached to electrical alternators) the speed of the water can’t be altered and hence the head developed by the turbine stays the same. Then the only other factor that can be changed is the discharge of water to control the power, and to do that the area of the flow needs to be controlled. Flywheel is only used to store energy, not governing.
