Derive transfer function for speed response for load change in turbine generator set in the absence of governor. Also explain how isochronous governor can be incorporated together with turbine and generator with block diagram.

What do you mean by Isochronous Governor? What will be the problem if two hydropower plants with isochronous governor are operated in parallel to supply a common load?

Two generators of 250 MW and 500 MW capacities respectively are operating in parallel and connected to a common bus. When each generator is half loaded, they operate at a common frequency of 50 Hz. Their droop characteristics are 4% and 2% respectively. When the system load is increased, the frequency decreases to 49.5 Hz. Calculate the increase in system load and load shared by each generator.
